Hostname and Domain name

| When I change my hostname and domain name using the hostname [localname] and the domainname [nisname] commands, it changes it only for that session. So when I reboot and come back it's back to where it was before. Is there some configuration file I need to put this in to make the change permanent? | |

| Use linuxconf or netconf to change the hostname permanently. | |

| You could also edit /etc/hosts | |

| What would I put in /etc/hosts?
What I did was put the following:
127.0.0.1 host.domain.net host
Not host.domain.net host literally. I replaced that with what I wanted my host and domain to be.
Now if this IS right and it should work - which it don't - it's possible this loopback address could be blocked. I installed portsentry rececntly and to play with it I have nmap'ed myself which may have blocked 127.0.0.1. Or maybe my /etc/hosts file is wrong. Opinions? | |

| Correction: That did change my hostname but not my domain-name. | |

| Nevermind, after some research I got it by editing /etc/sysconfig/network. | |

| Hehe, glad to hear you got everything working.
Btw, portsentry has a config file (can't recall the name off the top of my head) where you can list IPs and/or subnets that you don't want blocked. By default 127.0.0.1 is listed. It would be a good idea to list the rest of the addresses used by your interfaces as well as other important addresses like your DNS servers to prevent someone from DOSing you with spoofed packets. |
