12 1.1 Where do I get DXSpider?
13 1.2 How do I use the patches?
14 1.3 If I use a tarball to overwrite my installation, what happens to my configuration?
15 1.4 I am running RedHat 5.2 and I am getting strange errors, what is wrong?
18 2.1 How can I get Spider to restart automatically if it crashes?
19 2.2 How can I monitor traffic to and from a node or user?
20 2.3 My neighbouring node cannot use the RCMD command to me, he just keeps getting the "tut tut" message.
21 2.4 I do not seem to be sending any bulletin mail to my link partners, what is wrong?
22 2.5 How can I automatically limit the amount of debug logfiles that are stored?
23 2.6 I updated my Linux distribution and now Spider cannot read the users file or the dupefile, what is the problem?
24 2.7 Since I last updated I seem to be getting duplicate spots appearing.
25 2.8 I have deleted a message but it is still there, why?

44 Patching is done in the standard linux way ...
48 zcat /tmp/patch-1.40 | patch -p0
52 assuming the patch version you are using is 1.40 and resides in /tmp!
55 Be aware that each patch assumes the previous patch has been applied.
56 That is to say if you are patching from version 1.38 to 1.40 you would
57 first need to apply patch-1.39 and then patch-1.40.

63 The tarballs are designed to not overwrite your existing configuration
64 and can be used at any time to update your Spider software. All the
65 key files have the suffix .issue (eg. DXVars.pm.issue) at default.

71 The version of Perl that comes with 5.2 seems to be some kind of pre-
72 release and is broken. You can get a new version of perl from
73 www.dxcluster.org or ftp://updates.redhat.com. Don't forget to patch
74 it with the CPAN modules.

\ba_

\bl command like
101 tail -f /spider/data/debug/167.dat |grep G0VGS
105 or in later versions of Spider, there is a command called _

117 Assuming that the permissions are set correctly (perm level 5
118 required), it could be that the home_node is set incorrectly. You can
119 reset the home_node using the _
\bs_
\bp_
\bo_
\bo_
\bf command like this ..
123 spoof gb7adx set/home gb7adx
127 Assuming that the node_call you are changing is gb7adx.

142 Use the tmpwatch command. Create a file in /etc/cron.daily/
143 containing the line ...
147 /usr/sbin/tmpwatch -f 240 /spider/data/debug
151 Remember to make it executable!
153 This will limit your debug data down to the last 10 days

159 Almost certainly this is a change in the db format of perl. Follow
160 these few steps to correct the problem.
163 +
\bo stop the cluster (disable any autostart in inittab)
167 +
\bo issue the command perl user_asc
169 +
\bo restart the cluster
171 That should solve the problem.

177 What has probably happened is that the dupefile has got corrupted in
178 some way. Simply delete the /spider/data/dupefile and restart the
179 cluster. It may take a little time to become fully functional but
180 should solve your problem.

185 This is now the way messages are handled for deletion in Spider. If
186 you look closely you will see a 'D' following the message number.
187 This message is marked for deletion and will be deleted in 2 days if
188 nothing further is done. Optionally you can use the command
