42 Patching is done in the standard linux way ...
46 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.

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

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

\bt_

107 which case you simply type ..

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