4 Novell is a company any seasoned IT manager has to admire. It has become increasingly
5 Linux-friendly and is emerging out of a deep regression that almost saw the company
6 disappear into obscurity. Novell's SUSE Linux hosts the NetWare server and it is the
7 platform of choice to which many older NetWare servers are being migrated.
8 It will be interesting to see what becomes of NetWare over time.
9 Meanwhile, there can be no denying that Novell is a Linux company.

15 Whatever flavor of Linux is preferred in your environment, whether Red Hat, Debian,
16 Gentoo, Mandrake, or SUSE (Novell), the information in this chapter should be read with
17 the knowledge that file locations may vary a little; even so, the information
18 in this chapter should provide something of value.
19 </p><p>

21 Contributions to this chapter were made by Misty Stanley-Jones, a UNIX administrator of many
22 years who surfaced on the Samba mailing list with a barrage of questions and who
23 regularly helps other administrators to solve thorny Samba migration questions.

29 One wonders how many NetWare servers remain in active service. Many are being migrated
30 to Samba on Linux. Red Hat Linux, SUSE Linux 9.x, and SUSE Linux Enterprise Server 9 are
31 ideal target platforms to which a NetWare server may be migrated. The migration method
32 of choice is much dependent on the tools that the administrator finds most natural to use.
33 The old-hand NetWare guru will likely want to use tools like the NetWare NLM for
34 <code class="literal">rsync</code> to migrate files from the NetWare server to the Samba server.
35 The UNIX administrator might prefer tools that are part of the Mars_NWE (Martin Stovers' NetWare
36 Emulator) open source package. The MS Windows network administrator will likely make use of the
37 NWConv utility that is a part of Windows NT4 Server. Whatever your tool of choice,
38 migration will be filled with joyous and challenging moments though probably not
39 concurrently.
40 </p><p>
41 The priority that Misty faced was one of migration of the data files off the NetWare 4.11
42 server and onto a Samba-based Windows file and print server. This chapter does not pretend
43 to document all the different methods that could be used to migrate user and group accounts
44 off a NetWare server. Its focus is on migration of data files.
45 </p><p>
46 This chapter tells its own story, so ride along. Maybe the information presented here
47 will help to smooth over a similar migration challenge in your favorite networking environment.
48 </p><p>
49 File paths have been modified to permit use of RPM packages provided by Novell. In the
50 original documentation contributed by Misty, the Courier-IMAP package had been built
51 directly from the original source tarball.

54 Misty Stanley-Jones was recruited by Abmas to administer a network that had
55 not received much attention for some years and was much in need of a makeover.
56 As a brand-new sysadmin to this company, she inherited a very old Novell file server
57 and came with a determination to change things for the better.
58 </p><p>
59 A site survey turned up the following details for the old NetWare server:
60 </p><table class="simplelist" border="0" summary="Simple list"><tr><td>200 MHz MMX processor</td></tr><tr><td>512K RAM</td></tr><tr><td>24 GB disk space in RAID1</td></tr><tr><td>Novell 4.11 patched to service pack 7</td></tr><tr><td>60+ users</td></tr><tr><td>7 network-attached printers</td></tr></table><p>
61 The company had outgrown this server several years before and was dealing with
62 severe growing pains. Some of the problems experienced were:
63 </p><div class="itemizedlist"><ul type="disc"><li><p>Very slow performance</p></li><li><p>Available storage hovering around the 5% range</p><div class="itemizedlist"><ul type="circle"><li><p>Extremely slow print spooling.</p></li><li><p>
64 Users storing information on their local hard
65 drives, causing backup integrity problems
66 </p></li></ul></div></li></ul></div><p>
67 <a class="indexterm" name="id2606123"></a>
68 At one point disk space had filled up to 100 percent, causing the payroll database
69 to become corrupt. This caused the accounting department to be down for over
70 a week and necessitated deployment of another file server. The replacement
71 server was created with very poor security and design considerations from
72 a discarded desktop PC.
73 </p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id2606137"></a>Assignment Tasks</h3></div></div></div><p>
74 Misty has provided this summary of her migration experience in the hope
75 that it will help someone to avoid the challenges she faced. Perhaps her
76 configuration files and background will accelerate your learning as you
77 grapple with a similar migration challenge. Let there be no confusion,
78 the information presented in this chapter is provided to demonstrate
79 how Misty dealt with a particular NetWare migration requirement, and
80 it provides an overall approach to the implementation of a Samba-3
81 environment that is significantly divergent from that presented in
82 <a class="link" href="happy.html" title="Chapter 5. Making Happy Users">&#8220;Making Happy Users&#8221;</a>.
83 </p><p>
84 The complete removal of all site-specific information in order to produce
85 a generic migration solution would rob this chapter of its character.
86 It should be recognized, therefore, that the examples given require
87 significant adaptation to suit local needs and thus
88 there are some gaps in the example files. That is not Misty's fault;it
89 is the result of treatment given to her files in an attempt to make
90 the overall information more useful to you.

92 <a class="indexterm" name="id2606174"></a>
93 After management reviewed a cost-benefit report as well as an estimated
94 time-to-completion, approval was given proceed with the solution proposed.
95 The server was built from purchased components. The total project cost
96 was $3,000. A brief description of the configuration follows:
97 </p><table class="simplelist" border="0" summary="Simple list"><tr><td>
98 3.0 GHz P4 Processor
99 </td></tr><tr><td>
100 1 GB RAM
101 </td></tr><tr><td>
102 120 GB SATA operating system drive
103 </td></tr><tr><td>
104 4 x 80 GB SATA data drives (RAID5 240 GB capacity)
105 </td></tr><tr><td>
106 2 x 80 GB SATA removable drives for online backup
107 </td></tr><tr><td>
108 A DLT drive for asynchronous offline backup
109 </td></tr><tr><td>
110 SUSE Linux Professional 9.1
111 </td></tr></table><p>
112 The new system has operated for 6 months without problems. Over the past months
113 much attention has been focused on cleaning up desktops and user profiles.

119 A decision to use LDAP was made even though I knew nothing about LDAP except that
120 I had been reading the book &#8220;<span class="quote">LDAP System Administration,</span>&#8221; by Gerald Carter.
121 LDAP seemed to provide some of the functionality of Novell's e-Directory Services
122 and would provide centralized authentication and identity management.
123 </p><p>
124 <a class="indexterm" name="id2606276"></a>
125 <a class="indexterm" name="id2606282"></a>
126 <a class="indexterm" name="id2606289"></a>
127 Building the LDAP database took a while and a lot of trial and error. Following
128 the guidance I obtained from &#8220;<span class="quote">LDAP System
129 Administration,</span>&#8221; I installed OpenLDAP (from RPM; later I compiled
130 a more current version from source) and built my initial LDAP tree.

139 <a class="indexterm" name="id2606360"></a>
140 <a class="indexterm" name="id2606367"></a>
141 The first challenge was to create a company white pages, followed by manually
142 entering everything from the printed company directory. This used only the inetOrgPerson
143 object class from the OpenLDAP schemas. The next step was to write a shell script that
144 would look at the <code class="filename">/etc/passwd</code> and <code class="filename">/etc/shadow</code>
145 files on our mail server and create an LDIF file from which the information could be
146 imported into LDAP. This would allow use of LDAP for Linux authentication, IMAP, POP3,
147 and SMTP.
148 </p><p>
149 Because a decision was made to use Courier-IMAP the schema &#8220;<span class="quote">authldap.schema</span>&#8221;
150 from the Courier-IMAP source, tarball is necessary to resolve Courier-specific LDAP directory
151 needs. Where the Courier-IMAP file provided by SUSE is used, this file is named
152 <code class="filename">courier.schema</code>.
153 </p><p>
154 Looking back, it would have been much easier to populate the LDAP directory using a convenient
155 tool such as <code class="literal">phpLDAPAdmin</code> from the outset. An excessive amount of time was
156 spent trying to generate LDIF files that could be parsed using the <code class="literal">ldapmodify</code>
157 so that necessary changes could be written to the directory. This was a learning experience!
158 </p><p>
159 An attempt was made to use the PADL POSIX account migration scripts, but I gave up trying to
160 make them work. Instead, even though it is most inelegant, I wrote a simple script that did
161 what I needed. It is enclosed as a simple example to demonstrate that you do not need to be
162 a guru to make light of otherwise painful repetition.

188 The PADL MigrationTools are recommended for migration of the UNIX account information into
189 the LDAP directory. The tools consist of a set of Perl scripts for migration of users, groups,
190 aliases, hosts, netgroups, networks, protocols, PRCs, and services from the existing ASCII text
191 files (or from a name service such as NIS). This too set can be obtained from the <a class="ulink" href="http://www.padl.com" target="_top">PADL Web site</a>.

194 The following software must be installed on the SUSE Linux Enterprise Server to perform
195 this migration:
196 </p><table class="simplelist" border="0" summary="Simple list"><tr><td>courier-imap</td></tr><tr><td>courier-imap-ldap</td></tr><tr><td>nss_ldap</td></tr><tr><td>openldap2-client</td></tr><tr><td>openldap2-devel (only for Samba compilation)</td></tr><tr><td>openldap2</td></tr><tr><td>pam_ldap</td></tr><tr><td>samba-3.0.20 or later</td></tr><tr><td>samba-client-3.0.20 or later</td></tr><tr><td>samba-winbind-3.0.20 or later</td></tr><tr><td>smbldap-tools Version 0.9.1</td></tr></table><p>
197 Each software application must be carefully configured in preparation for migration.
198 The configuration files used at Abmas are provided as a guide and should be modified
199 to meet needs at your site.

421 In my setup, users authenticate via PAM and NSS using LDAP-based accounts.
422 The configuration file that controls the behavior of the PAM <code class="literal">pam_unix2</code>
423 module is shown in <a class="link" href="nw4migration.html#sbepu2" title="Example 10.3. The PAM Control File /etc/security/pam_unix2.conf">&#8220;The PAM Control File /etc/security/pam_unix2.conf&#8221;</a> file.
424 This works out of the box with the configuration files in this chapter. It
425 enables you to have no local accounts for users (it is highly advisable
426 to have a local account for the root user). Traps for the unwary include the following:

432# which will be used for authentication, account management and

436# At first, pam_unix2 will read this file and then uses the local

479 Having gained a solid understanding of LDAP and a relatively workable LDAP tree
480 thus far, it was time to configure Samba. I compiled the latest stable Samba and
481 also installed the latest <code class="literal">smbldap-tools</code> from

496 Note: During the process of building the new server, I kept data files
497 up to date with the Novell server via use of <code class="literal">rsync</code>.
498 On a separate system (my workstation in fact), which could be rebooted
499 whenever necessary, I set up a mount point to the Novell server via
500 <code class="literal">ncpmount</code>. I then created a
501 <code class="filename">rsyncd.conf</code> to share that mount point out to my
502 new server, and synchronized once an hour. The script I used to synchronize
503 is shown in <a class="link" href="nw4migration.html#sbersync" title="Example 10.9. Rsync Script">&#8220;Rsync Script&#8221;</a>. The files exclusion list I used
504 is shown in <a class="link" href="nw4migration.html#sbexcld" title="Example 10.10. Rsync Files Exclusion List /root/excludes.txt">&#8220;Rsync Files Exclusion List /root/excludes.txt&#8221;</a>. The reason I had to have the
505 <code class="literal">rsync</code> daemon running on a system that could be
506 rebooted frequently is because <code class="constant">ncpfs</code>
507 (part of the MARS NetWare Emulation package) has a nasty habit of creating stale
508 mount points that cannot be recovered without a reboot. The reason for hourly
509 synchronization is because some part of the chain was very slow and
510 performance-heavy (whether <code class="literal">rsync</code> itself, the network,
511 or the Novell server, I am not sure, but it was probably the Novell server).

553 After Samba was configured, I initialized the LDAP database. The first
554 thing I had to do was store the LDAP password in the Samba configuration by
555 issuing the command (as root):
556</p><pre class="screen">
557<code class="prompt">root# </code> smbpasswd -w verysecret
558</pre><p>
559 where &#8220;<span class="quote">verysecret</span>&#8221; is replaced by the LDAP bind password.
560 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
561The Idealx smbldap-tools package can be configured using a script called
562<code class="literal">configure.pl</code> that is provided as part of the tool. See <a class="link" href="happy.html" title="Chapter 5. Making Happy Users">&#8220;Making Happy Users&#8221;</a>
563for an example of its use. Many administrators, like Misty, choose to do this manually
564so as to maintain greater awareness of how the tool-chain works and possibly to avoid
565undesirable actions from occurring unnoticed.
566</p></div><p>
567 Now Samba was ready for use and it was time to configure the smbldap-tools. There are two
568 relevant files, which are usually put into the directory
569 <code class="filename">/etc/smbldap-tools</code>. The main file,
570 <code class="filename">smbldap.conf</code> is shown in <a class="link" href="nw4migration.html#ch8ideal" title="Example 10.11. Idealx smbldap-tools Control File Part A">&#8220;Idealx smbldap-tools Control File Part A&#8221;</a>.

766masterPw="verysecret"
767</pre><p>
768 </p><p>
769 The next step was to run the <code class="literal">smbldap-populate</code> command, which populates
770 the LDAP tree with the appropriate default users, groups, and UID and GID pools.
771 It creates a user called Administrator with UID=0 and GID=0 matching the
772 Domain Admins group. This is fine because you can still log on as root to a Windows system,
773 but it will break cached credentials if you need to log on as the administrator
774 to a system that is not on the network.
775 </p><p>
776 After the LDAP database has been preloaded, it is prudent to validate that the
777 information needed is in the LDAP directory. This can be done done by restarting
778 the LDAP server, then performing an LDAP search by executing:
779</p><pre class="screen">
780<code class="prompt">root# </code> ldapsearch -W -x -b "dc=abmas,dc=biz"\
781 -D "cn=Manager,dc=abmas,dc=biz" \

783Enter LDAP Password:

821 With the LDAP directory now initialized, it was time to create the Windows and POSIX
822 (UNIX) group accounts as well as the mappings from Windows groups to UNIX groups.
823 The easiest way to do this was to use <code class="literal">smbldap-groupadd</code> command.
824 It creates the group with the posixGroup and sambaGroupMapping attributes, a
825 unique GID, and an automatically determined RID. I learned the hard way not to
826 try to do this by hand.
827 </p><p>
828 <a class="indexterm" name="id2609570"></a>
829 <a class="indexterm" name="id2609577"></a>
830 <a class="indexterm" name="id2609584"></a>
831 After I had my group mappings in place, I added users to the groups (the users
832 don't really have to exist yet). I used the <code class="literal">smbldap-groupmod</code>
833 command to accomplish this. It can also be done manually by adding memberUID
834 attributes to the group entries in LDAP.
835 </p><p>
836 <a class="indexterm" name="id2609604"></a>
837 <a class="indexterm" name="id2609611"></a>
838 <a class="indexterm" name="id2609618"></a>
839 The most monumental task of all was adding the sambaSamAccount information to each
840 already existent posixAccount entry. I did it one at a time as I moved people onto
841 the new server, by issuing the command:
842</p><pre class="screen">
843<code class="prompt">root# </code> smbldap-usermod -a -P username
844</pre><p>
845 <a class="indexterm" name="id2609640"></a>
846 <a class="indexterm" name="id2609647"></a>
847 <a class="indexterm" name="id2609654"></a>
848 I completed that step for every user after asking the person what his or her current
849 NetWare password was. The wiser way to have done it would probably have been to dump the
850 entire database to an LDIF file. This can be done by executing:
851</p><pre class="screen">
852<code class="prompt">root# </code> slapcat &gt; somefile.ldif
853</pre><p>
854 <a class="indexterm" name="id2609678"></a>
855 <a class="indexterm" name="id2609684"></a>
856 Then update the LDIF file created by using a Perl script to parse and add the
857 appropriate attributes and objectClasses to each entry, followed by re-importing
858 the entire database into the LDAP directory.
859 </p><p>
860 Rebuilding of the LDAP directory can be done as follows:
861</p><pre class="screen">
862<code class="prompt">root# </code> rcldap stop
863<code class="prompt">root# </code> cd /data/ldap
864<code class="prompt">root# </code> rm *bdb _* log*
865<code class="prompt">root# </code> su - ldap -c "slapadd -l somefile.ldif"
866<code class="prompt">root# </code> rcldap start
867</pre><p>
868 This can be done at any time and for any reason, with no harm to the database.
869 </p><p>
870 I first added a test user, of course. The LDIF for this test user looks like
871 this, to give you an idea:
872</p><pre class="screen">
873# Entry 1: cn=Test User,ou=people,ou=corp,dc=abmas,dc=biz

937 So now I could log on with a test user from the machine w2kengrspare. It was all well and
938 good, but that user was in no groups yet and so had pretty boring access. I fixed that
939 by writing the login script! To write the login script, I used
940 <a class="ulink" href="http://www.kixtart.org" target="_top">Kixtart</a> because it will work
941 with every architecture of Windows, has an active and helpful user base, and was both
942 easier to learn and more powerful than the standard netlogon scripts I have seen.
943 I also did not have to do a logon script per user or per group.
944 </p><p>
945 <a class="indexterm" name="id2609813"></a>
946 I downloaded Kixtart and put the following files in my netlogon share:
947</p><pre class="screen">
948KIX32.EXE
949KX32.dll
950KX95.dll &lt;-- Not needed unless you are running Win9x clients.
951kx16.dll &lt;-- Probably not needed unless you are running DOS clients.
952kxrpc.exe &lt;-- Probably useless as it has to run on the server and can
953 only be run on NT. It's for Windows 95 to become group-aware.
954 We can get around the need.
955</pre><p>
956 </p><p>
957 <a class="indexterm" name="id2609844"></a>
958 I then wrote the <code class="filename">logon.kix</code> file that is shown in
959 <a class="link" href="nw4migration.html#ch8kix" title="Example 10.15. Kixtart Control File File: logon.kix">&#8220;Kixtart Control File File: logon.kix&#8221;</a>. I chose to keep it all in one file, but it

1117 As you can see in the script, I redirected the My Documents to the user's home
1118 share if he or she were not in the Laptop group. I also added printers on a
1119 group-by-group basis, and if applicable I set the group printer. For this to
1120 be effective, the print drivers must be installed on the Samba server in the
1121 <code class="filename">[print$]</code> share. Ample documentation exists about how to
1122 do that, so it is not covered here.
1123 </p><p>
1124 I call this script via the logon.bat script in the [netlogon] directory:
1125</p><pre class="screen">
1126\\corpsrv\netlogon\kix32 \\corpsrv\netlogon\logon.kix /f
1127</pre><p>
1128 I only had to fully qualify the paths for Windows 9x, as Windows NT and
1129 greater automatically add [NETLOGON] to the path.
1130 </p><p>
1131 Also of note for Win9x is that the drive mappings and printer setup will not
1132 work because they rely on RPC. You merely have to put the appropriate settings
1133 into the <code class="filename">c:\autoexec.bat</code> file or map the drives manually.
1134 One option is to check the OS as part of the Kixtart script, and if it
1135 is Win9x and is the first login, copy a premade
1136 <code class="filename">autoexec.bat</code> to the <code class="filename">C:</code> drive. I
1137 have only three such machines, and one is going away in the very near future,
1138 so it was easier to do it by hand.
1139 </p><p>
1140 <a class="indexterm" name="id2610141"></a>
1141 At this point I was able to add the users. This is the part that really falls
1142 into upgrade. I moved the users over one group at a time, starting with the
1143 people who used the least amount of resources on the network. With each group
1144 that I moved, I first logged on as a standard user in that group and took
1145 careful note of the environment, mainly the printers he or she used, the PATH,
1146 and what network resources he or she had access to (most importantly, which ones
1147 the user actually needed access to).
1148 </p><p>
1149 I then added the user's SambaSamAccount information as mentioned earlier,
1150 and join the computer to the domain. The very first thing I had to do was to
1151 copy the user's profile to the new server. This was very important, and I really
1152 struggled with the most effective way to do it. Here is the method that worked
1153 for every one of my users on Windows NT, 2000, and XP:
1154 </p><div class="procedure"><ol type="1"><li><p>
1155 Log in as the user on the domain. This creates the local copy
1156 of the user's profile and copies it to the server as he or she logs out.
1157 </p></li><li><p>
1158 Reboot the computer and log in as the local machine administrator.
1159 </p></li><li><p>
1160 Right-click My Computer, click Properties, and navigate to the
1161 user profiles tab (varies per version of Windows).
1162 </p></li><li><p>
1163 Select the user's local profile <code class="constant">(COMPUTERNAME\username)</code>,
1164 and click the <code class="literal">Copy To</code> button.
1165 </p></li><li><p>
1166 In the next dialog, copy it directly to the profiles share on the
1167 Samba server (in my case \\PDCname\profiles\user\&lt;architecture&gt;.
1168 You will have had to make a connection to the share as that
1169 user (e.g., Windows Explorer type \\PDCname\profiles\username).
1170 </p></li><li><p>
1171 When the copy is complete (it can take a while) log out, and log back in
1172 as the user. All of his or her settings and all contents of My Documents,
1173 Favorites, and the registry should have been copied successfully.
1174 </p></li><li><p>
1175 If it doesn't look right (the dead giveaway is the desktop background),
1176 shut down the computer without logging out (power cycle) and try logging
1177 in as the user again. If it still doesn't work, repeat the steps above.
1178 I only had to ever repeat it once.
1179 </p></li></ol></div><p>
1180 Words to the Wise:
1181 </p><div class="itemizedlist"><ul type="disc"><li><p>
1182 If the user was anything other than a standard user on his or her system
1183 before, you will save yourself some headaches by giving him or her identical
1184 permissions (on the local machine) as his or her domain account <span class="emphasis"><em>before</em></span>
1185 copying the profile over. Do this through the User Administrator
1186 in the Control Panel, after joining the computer to the domain and
1187 before logging on as that user for the first time. Otherwise the user will
1188 have trouble with permissions on his or her registry keys.
1189 </p></li><li><p>
1190 If any application was installed for the user only, rather than for
1191 the entire system, it will probably not work without being reinstalled.
1192 </p></li></ul></div><p>
1193 After all these steps are accomplished, only cleanup details are left. Make sure user's
1194 shortcuts and Network Places point to the appropriate place on the new server, check
1195 the important applications to be sure they work as expected and troubleshoot any problems
1196 that might arise, and check to be sure the user's printers are present and working. By the
1197 way, if there are any network printers installed as system printers (the Novell way),
1198 you will need to log in as a local administrator and delete them.
1199 </p><p>
1200 For my non-laptop systems, I would then log in and out a couple times as the user
1201 to be sure that his or her registry settings were modified, and then I was finished.
1202 </p><p>
1203 Some compatibility issues that cropped up included the following:
1204 </p><p>
1205 Blackberry client: It did not like having its registry settings moved around
1206 and so had to be reinstalled. Also, it needed write permissions to a portion of
1207 the hard drive, and I had to give it those manually on the one system where
1208 this was an issue.
1209 </p><p>
1210 CAMedia: Digital camera software for Canon cameras caused all kinds of trouble
1211 with the registry. I had to use the Run as service to open the registry of
1212 the local user while logged in as the domain user, and give the domain user
1213 the appropriate permissions to some registry keys, then export that portion
1214 of the registry to a file. Then, as the domain user, I had to import that file
1215 into the registry.
1216 </p><p>
1217 Crystal Reports version 7: More registry problems that were solved by recopying
1218 the user's profile.
1219 </p><p>
1220 Printing from legacy applications: I found out that Novell sends its jobs to
1221 the printer in a raw format. CUPS sends them in PostScript by default. I had
1222 to make a second printer definition for one printer and tell CUPS specifically
1223 to send raw data to the printer, then assign this printer to the LPT port with
1224 Kixtart's version of the net use command.
1225 </p><p>
1226 These were all eventually solved by elbow grease, queries to the Samba mailing
1227 list and others, and diligence. The complete migration took about 5 weeks.
1228 My userbase is relatively small but includes multiple versions of Windows,
1229 multiple Linux member servers, a mechanized saw, a pen plotter, and legacy
1230 applications written in Qbasic and R:Base, just to name a few. I actually
1231 ended up making some of these applications work better (or work again, as
1232 some of them had stopped functioning on the old server) because as part of
1233 the process I had to find out how things were supposed to work.
1234 </p><p>
1235 The one thing I have not been able to get working is a very old database that
1236 we had around for reference purposes; it uses Novell's Btrieve engine.
1237 </p><p>
1238 As the resources compare, I went from 95 percent disk usage to just around 10 percent.
1239 I went from a very high load on the server to an average load of between one
1240 and two runnable processes on the server. I have improved the security and
1241 robustness of the system. I have also implemented
1242 <a class="ulink" href="http://www.clamav.net" target="_top">ClamAV</a> antivirus software,
1243 which scans the entire Samba server for viruses every 2 hours and
1244 quarantines them. I have found it much less problematic than our ancient
1245 version of Norton Antivirus Corporate Edition, and much more up-to-date.
1246 </p><p>
1247 In short, my users are much happier now that the new server is running, and that
1248 is what is important to me.
