AIX

>where are these so called config files in aix? All i know was linux,solaris and HP.

Sprellarinn has just told you that, and this is the main difference with the 2 other OS you mentionned: AIX uses an ODM stored in NVRAM...
You ca go and modify the data in the ODM if you wish, but my experience is a corrupted ODM can be HELL...

Sorry, but: no. The ODM is stored not in NVRAM, but in the directories /etc/objrepos and /usr/lib/objrepos for the standard AIX part, some middleware extensions have their own ODM, for example HACMP in /usr/es/sbin/cluster/etc/objrepos and /etc/es/objrepos.

To clear the confusion about lasting/nonlasting IP changes up:

To change the IP adress until the next reboot use "ifconfig". To change routing accordingly in the same non-permanent way use "route delete ..." and "route add ...".

To change IP adressses permanently use "chdev", as Sprellarinn has said. To change the routing accordingly you will have to use "chdev ... inet0" as the routes are stored in the inet0 pseudodevice.

I hope this helps.

ifconfig -a | grep inet
inet 10.118.5.43 netmask 0xffffff00 broadcast 10.118.5.255 inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255

Could you please help me, how to change IP permanently using command line.

output:

inet 10.118.6.43 netmask 0xffffff00 broadcast 10.118.6.255
inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255

Use the "chdev" command on the device en0. You can find out how to use "chdev" by issuing "man chdev" on the commandline and you can get the names of the attributes to change from the output of "lsattr -El en0".

I hope this helps.
