what file contains IP info?

[inkedmn]

when a machine recieves an IP address, netmask, etc from a dhcp server (or when it's statically assigned), which would contain that information?

also, does one file contain all of the following? :
-IP address
-Subnet mask
-Default Gateway
-DNS server(s)
-Whether the info is from DHCP or manual entry?

the reason i ask, is i'm going to attempt to code a small GUI app in python that's akin to the output of "winipcfg" in windows 95.

thanks for all your help!

A lot of that information can be gotten from ifconfig and/or netstat, but I'm not sure what file it might reside in. That's an interesting question...I wonder if it's on the /proc filesystem...hmmm :confused:

Check out the following files:
/etc/sysconfig/network gives host & domain name
/etc/sysconfig/network-scripts/ifcfg-eth0 (assuming your network interface is ethernet) gives boot protocol (static IP or DHCP), netmask and interface device (eth0)
/etc/resolv.conf gives dns servers


I'm not sure about the gateway - the "route" command will give you that!

cool, thanks for the replies!

Those files are distribution-specific, and as such, should not be used.

Let me also note that the /proc filesystem is kernel-dependent, and therefore should also not be used.
