Red Hat Bugzilla – Bug 202847
Client initscript doesn't work for netconsole
Last modified: 2014-03-16 23:01:28 EDT
Description of problem: Intial problems found: 1) [ "mac_ip" .. on line 130 ... shouldn't that be [ "$mac_ip" .. 2) still doesn't resolve the address/arp right 3) when I hardcode it in the initscript: initializing netconsole: netconsole: Unknown parameter 'netlog' Version-Release number of selected component (if applicable): netdump-0.7.16-5
the mac_ip line should definately have a $ in front of it, and there also needs to be an extra equals sign. Thats fixed in release -6. As for your other problems, those sounds like they might be config related. Please give the attached patch a try and see if it fixes your problem. If not, please reply with your netdump setup, as well as a details description of your network topology (including mac and ip addresses) between your client and server. Thank you!

(Aside from this, the fact is that most of the netdump package is obsolete. :) ) [root@apone ~]# grep -v "^#" /etc/sysconfig/netdump NETLOGADDR=nostromo.devel.redhat.com NETLOGPORT=6666 [root@apone ~]# service netdump start netdump: cannot arp on eth0 inicializuji netconsole FATAL: Error inserting netconsole (/lib/modules/2.6.18-1.2708.fc6/kernel/drivers/net/netconsole.ko): Unknown symbol in module, or unknown parameter (see dmesg) [SELHALO] (ignore the czech) So, looking some more: - the parameter to the kernel is netconsole; the script has netlog - the traceroute awk line is: trc_output="$(traceroute -i $DEV -n -m 1 $host_ip 2> /dev/null)" if [ $? -eq 0 ]; then trc_output="$(echo $trc_output | grep '^1 ' | awk '{print $2}')" except that the '1' in the traceroute output has a space preceeding it. Oh, and the whole sequence is probably better replaced with something like: ip -o route get to $host_ip dev $DEV | awk '{ print $1 }' :) Patch attached.

bill makes a good point in that FC6 will be using kdump moving forward, but I'll check this in just to make sure we have the fix in place should we need it.

netdump-0.7.16-13 has been pushed for fc6, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
