Changing server ip address

I setup the Debian perfect setup and now I am setting up ipcop. I want to change the ip address to the box. anyone know how to do this? thanks.

 

ifconfig eth0 192.168.1.102 netmask 255.255.255.0 broadcast 192.168.1.255

 

changing ip address

I tried to change the ip address by modifying vi /etc/network/interfaces. Then I went into ipsconfig and changed the ip address to my static ip in the managment area. then I changed the ip addresses on the sites I had setup to the static ip for my server. Then I changed the dns to the new static ip. I changed all sites ips to point to my server. I am having mail issues. Can I run this command to maybe fix what I shuld have waited for an answer for or what? here is the error log from my mail log.

Do you have valid nameservers in /etc/resolv.conf?
Does

Code:

dig google.com

work?

 

Yes dig google worked. however I have another thread you are helping me with. I do not know to continue this one. the resolv.conf is here. search domain_not_set.invalid
nameserver 192.168.1.1
I guess that might be the issue.How can I chage that back? or do I enter the domain for my box there?

 

You can leave out the search line, it's optional.
