+ | ====== Linux kernel netconsole setup with LILO and netcat ====== | ||
+ | Here's a tested combination of settings, assuming that the kernel has netconsole support compiled in (not a module): | ||
+ | |||
+ | In ''/etc/lilo.conf'', the section may look like: | ||
+ | |||
+ | <code> | ||
+ | image=/boot/vmlinuz-2.6.18-194.8.1.el5.028stab070.2.owl3 | ||
+ | label=070.2.owl3 | ||
+ | append="panic=10 netconsole=444@192.168.xxx.src/eth1,666@192.168.xxx.dst/00:11:22:33:44:55" | ||
+ | </code> | ||
+ | |||
+ | Of course, proper source IP address, interface name, and destination IP address and MAC address (same Ethernet segment/VLAN) need to be substituted. | ||
+ | |||
+ | On the temporary logging server, run (preferably under ''screen''): | ||
+ | |||
+ | nc -vul 666 | tee -a netcons-srcservername | ||
+ | |||
+ | Tested with OpenBSD-derived netcat that we have in [[http://www.openwall.com/Owl/|Owl]]. |
