Greetings, all.
I'm running 2.2r3, and I'm having some difficulties setting my FQDN. My IP
address is assigned via DHCP from a server here at work; I'm using pump.
The DHCP server is set up such that when it assigns an IP address, it
automatically updates the DNS tables on that server according to the
hostname that my machine supplies during the DHCP operation. However, I'm
still having some problems:
[rcclinux:~]$ hostname
rcclinux
[rcclinux:~]$ hostname --fqdn
rcclinux
[rcclinux:~]$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:03:47:87:B5:44
inet addr:172.16.116.195 Bcast:255.255.255.255 Mask:255.255.255.0
UP BROADCAST RUNNING MTU:1500 Metric:1

[rcclinux:~]$ nslookup 172.16.116.195
Server: moe.inetint.com
Address: 172.16.99.20
Name: rcclinux.inetint.com
Address: 172.16.116.195
My /etc/hosts file doesn't have anything except localhost and entries for
the various NIS servers, not all of which are in DNS. (I use NIS only for
password and group lookups; host lookups are entirely DNS.)
I really don't want to edit /etc/hosts every time my IP address changes,
and I don't know that there's a way to get pump to do this for me
automatically. Is there another way to set the FQDN?
I know that dhcpcd, in the dhcp-client package, allows you to run an
arbitrary script whenever the IP address changes, but I'm not sure how to
use this instead of pump. If I simply uninstall pump and replace it with
dhcp-client, will ifup automatically switch over? How do I specify
arguments (like the script to be run) to dhcpcd, given that it would be
invoked by ifup?
My /etc/resolv.conf file (which I think is created by pump) contains a
search line, but no domain line. I don't want to edit this, because pump
will overwrite it the next time it grabs an address.
Any suggestions would be most welcome.
Thanks in advance,
Richard
