Stories similar to Updating hostname in DNS with dyn. IP address

Hi all,

I am trying to exchange hostname and IP address of two AIX machines.

But i am confused as how to change it ? do i need to use "smitty mktcpip" or "smitty tcpip" ?

what is the difference between smitty mktcpip and smitty tcpip ?

Also anymore steps to follow or just updating using smitty is enough (hoping that no reboot is required)

Also below is the proce

So I noticed when you change your hostname, the hostname does not change in the dns entries..

Hostname not resolving.. 31 weeks 2 days ago

I recently began having issues with my Arch box not allowing connections based on hostname.  Not sure whats going on I can SSH into the box, view the webserver, ftp, etc assuming I am using the IP address.  If I use the hostname, nothing works.I can nslookup from a Windows machine and see the IP is resolved..

Before the switch to systemd, I was able to ssh between my two machines via user@hostname but now I get a "could not resolve hostname" error and have to use the IP address instead.

I have a problem that I'm dealing with from a long time... I'm creating an Android app that will get info of devices that are in the same subnet as an Android device. For example I give it ip address 192.168.0.3 and it shows that its hostname is xxxx and MAC Address xx:xx:xx... .

I tried to change my hostname according to this guide for Debian based system:

I edited /etc/hostname file run /etc/init.d/hostname start

Though there are errors. Always when I write a sudo command it tells me it can't recognize hostname. After I restarted the system, graphical environment wasn't working, startx command wasn't successful.

Propogating hostname to router 14 weeks 4 days ago

How do you propagate changes to your hostname from your Linux machine (I am using Linux Mint 13) to your router (I am using DG834Gv2)?

I changed the hostname in /etc/hostname and restarted. The router still resolves the old hostname to my IP address.

Thanks.

Repair DNS Hostname mac server 1 year 13 weeks ago

I am getting this problem when checking the hostname of my server

Primary address = 176.16.1.227

Current HostName = grandcentral.xx.xx.xx

The DNS hostname is not available, please repair DNS and re-run this tool.

dirserv:success = "success"

How can I repair the DNS to ensure I get a result like

Primary address = 10.20.30.3

Current HostName = host.example.com DNS HostName

I'm making some large-scale system hostname changes and this got me thinking...
