Re: [opensuse] Can't get remote kernel logging working.

Do you see anything on local console? If not, you may need to increase verbosity (dmesg -n). Отправлено с iPhone

I'm trying to log kernel messages on another machine to log a possible kernel crash. I got this working about two months ago on these same machines, running 13.1, but now it fails.

On the receiving machine I run as root:

netcat -u -l 6666 | tee -a remote_log

On sending machine I do, for testing:

netcat -u 192.168.1.15 6666 Hello world ^C

And it is duly printed on the other side. So far, so good.

I verify remote machine data:

# ifconfig eth0 Link encap:Ethernet HWaddr 00:03:0D:05:17:FC inet addr:192.168.1.15 Bcast:192.168.1.255 Mask:255.255.255.0 ...

Now I do:

modprobe netconsole cd /sys/kernel/config/netconsole/ mkdir target1 cd target1/

echo "00:03:0D:05:17:FC" > remote_mac echo 6666 > remote_port echo 192.168.1.15 > remote_ip cat dev_name echo 1 > enabled

I get this response in the log, verifiying that it is enabled:

<0.6> 2016-01-22 04:42:57 Telcontar kernel - - - [191845.722453] console [netcon0] enabled <0.6> 2016-01-22 04:42:57 Telcontar kernel - - - [191845.722456] netconsole: network logging started <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577279] netpoll: netconsole: local port 6665 <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577283] netpoll: netconsole: local IPv4 address 0.0.0.0 <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577284] netpoll: netconsole: interface 'eth0' <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577285] netpoll: netconsole: remote port 6666 <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577287] netpoll: netconsole: remote IPv4 address 192.168.1.15 <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577288] netpoll: netconsole: remote ethernet address 00:03:0d:05:17:fc <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577291] netpoll: netconsole: local IP 192.168.1.14 <0.6> 2016-01-22 04:43:05 Telcontar kernel - - - [191854.577293] netconsole: network logging started

Then I cause an event, like plugin in/out an USB stick, to cause messages to be printed - but nothing gets on the remote. Why? I must have done something wrong, but I can't see it.
