Hi,
I have just upgraded one server from 2.4.20 (with grsec) to latest WOLK-4.6s.
All seems to be working fine, however there is very strange issue with
network interfaces & MRTG.
Here is my problem in detail:
Server is runnig latest WOLK-4.6s, with GRSecurity ACLs enabled. Server has
one NIC, which is eth0, and 6 aliased IPs (let's say eth0 has IP 192.168.0.1,
while aliases (eth0:{0-5}) are IPs from 192.168.0.2 to 192.168.0.7). I
noticed that MRTG stopped working with SNMP, so I decided to check where the
problem is. I have looked over all MRTG's & SNMP's configs, and everything is
correct. The problem is that SNMP saying that "noSuchName", and MRTG fails to
work.
Now the interesting stuff happens - I tried to run MRTG's cfgmaker to
re-create mrtg.cfg. All went smooth, BUT when I opened mrtg.cfg to check eth0
params, I found that eth0 has IP 192.168.0.5, which is obviously pretty wrong
(eth0 is 192.168.0.1, while 192.168.0.5 is eth0:3 alias).
I do not know how come SNMP or/and MRTG think that my eth0 is 192.168.0.5. I
tried to SSH from the box to another box, and remote IP shown correctly -
192.168.0.1, but somehow locally, main IP is 192.168.0.5. I have tried to
disable GRSecurity - but still no luck..
Any ideas what it could be? I can send my .config, if anyone is interested.
thanks,
Mikhail.
