Setting AIX system name to FQDN

[Scott Lopez]

Set it using smit. Updating it from the command line does NOT update the
underlying database files where everything is stored. I learned this the
hard way, use smit for all system configuration.

How, if possible, can one permamently set the AIX system to use the FQDN
(fully qualified doamin name) convention.

I tried changing it using the uname command but it gets reset after a reboot.
For example:

# uname -n
myhost

# uname -S myhost.mydomain

# uname -n
myhost.mydomain

# /etc/reboot

# uname -n
myhost

I don't have this problem with other OS's (eg solaris, ultrix, osf1). Is
there away around this with AIX or is it not supported for some reason?

I think you have to wrestle with smit to change the name in the TCP/IP
Minimum Configuration & Startup menu.

The command smit runs starts with:
mktcpip -h'myname.my.fully.qualified.domain.name'

I suspect this name is kept somewhere in the ODM database, but I haven't
found it (yet:-).

Hope this helps,

The way around this is to modify the following line in /etc/rc.net
from:

/bin/uname -S`hostname|sed 's/\..*$//'` >>$LOGFILE 2>&1

to:

/bin/uname -S`hostname` >>$LOGFILE 2>&1

By default (not sure why) IBM strips the anything after the first "." in a
hostname set FQDN style (eg via mktcpip) when setting the uname.

Thanks to Bjorn Roden for pointing out the neccessary update.

If you have a DNS at your site, set the file /etc/resolv.conf with these
two lines:
domain <domain_name>
nameserver <ip address of the DNS>
