When I originally set-up the server I gave it a static IP address and all worked fine, i.e. I could ping by IP or DNS name.

However last week we moved a group of servers onto a different domain and these now need to use dynamic IP addresses. Now, I have set it so that it knows where the DHCP / DNS server is and it obtains an IP address with no problems, however I can't get it to register its hostname with the DNS server so that I can ping by DNS name.

It seems that when I go through the networking part I need to pass in a dotted IP address, which would be fine if the server was never rebooted, but this won't work in the real world.

Can anyone help please?

Thanks

1. Make sure bos.net.tcp.client is installed
2. Add this line to the end of /etc/dhcpcd.ini:
   
   updateDNS "/usr/sbin/dhcpaction '%s' '%s' '%s' '%s' A NONIM >> /tmp/updns.out 2>&1 "
   
   If you are using NIM, you need to do two things:
   • Change NONIM to NIM
   • http://www.pseriestech.org/forum/pse...-to-nim-9.html

Hi Fred,

I don't believe I'm using NIM (after reading your other thread) so I don't need to worry about this.

How can I tell whether the bos.net.tcp.client is installed - I already have an IP address so does this mean that it's installed?

I'll try changing the dhcpcd.ini file.

Thanks
Nick

I do:

lslpp -ch | egrep bos.net.tcp

The official way is:

lslpp -ch bos.net.tcp.client
