Hello, list,
I have a little problem, with netconsole.
It does not work for me.
On the "client":
modprobe netconsole netconsole=@/,514@192.168.2.100/
dmesg:
netconsole: local port 6665
netconsole: interface eth0
netconsole: remote port 514
netconsole: remote IP 192.168.2.100
netconsole: remote ethernet address ff:ff:ff:ff:ff:ff
netconsole: local IP 192.168.2.50
netconsole: network logging started
(kernel: 2.6.15-rc5, and 2.6.16-rc1,2)
On the server:
]# netcat -u -l -v -s 192.168.2.100 -p 514
192.168.2.100: inverse host lookup failed: Unknown host
listening on [192.168.2.100] 514 ...
And nothing comes.
The firewall is off on both system.
The ping comes from any direction.
If i try the remote and local syslog, it works well, two.
And in this case, the netlog only displays what the syslog is sends.
What can be the problem?
Thanks,
Janos

Perhaps your console log level is set too low. Fedora for instance is
very quiet by default.

Netconsole logging level is based off the _console log level_, which
defaults to quiet on recent Redhat releases. If it doesn't show up on
the console, netconsole doesn't see it either.

Sorry, i was not clear enough....
The system, what i want to debug is RedHat 9.0, with kernel 2.6.15, 2.6.16-*
The syslog server is Fedora, and the syslog to syslog messages is works, but
netconsole to syslog (and netconsole to netcat) is the problem, including
the init-message!
At this time i try to receive with another redhat 9, but it looks like the
netconsole did not working properly for me. :(
Thanks,

via Magic Sysrq + number (e.g., alt-sysrq-9)
or via (as root) "echo 9 > /proc/sysrq-trigger"
or via (as root) "echo 9 4 1 7 > /proc/sys/kernel/printk"
(first "cat /proc/sys/kernel/printk" and increase the first value).
For the first one, you need a kernel that has
CONFIG_MAGIC_SYSRQ=y
and also has /proc/sys/kernel/sysrq = 1
(echo 1 > /proc/sys/kernel/sysrq # to enable it)
