13 1.1 Where do I get DXSpider?
14 1.2 How do I use the patches?
15 1.3 If I use a tarball to overwrite my installation, what happens to my configuration?
16 1.4 I am running RedHat 5.2 and I am getting strange errors, what is wrong?
20 2.1 How can I get Spider to restart automatically if it crashes?
21 2.2 How can I monitor traffic to and from a node or user?
22 2.3 My neighbouring node cannot use the RCMD command to me, he just keeps getting the "tut tut" message.
23 2.4 I do not seem to be sending any bulletin mail to my link partners, what is wrong?
24 2.5 How can I automatically limit the amount of debug logfiles that are stored?
25 2.6 I updated my Linux distribution and now Spider cannot read the users file or the dupefile, what is the problem?
26 2.7 Since I last updated I seem to be getting duplicate spots appearing.

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

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

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

101 There are 2 ways to achieve this. You can use the _
\bt_
\ba_
\bi_
\bl command like
106 tail -f /spider/data/debug/167.dat |grep G0VGS
111 or in later versions of Spider, there is a command called _
\bw_
\ba_
\bt_
\bc_
\bh_

112 which case you simply type ..

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

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

166 Almost certainly this is a change in the db format of perl. Follow
167 these few steps to correct the problem.
170 +
\bo stop the cluster (disable any autostart in inittab)
174 +
\bo issue the command perl user_asc
176 +
\bo restart the cluster
178 That should solve the problem.

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