Finding out IPs from dhcp logs.

[Guest frew]

Right, often at lan parties we need to know a few people's IP addresses and I was wondering what log would have that information. I have seen it before in /var/log/info I think, But I dont want to wade through something like that. Thx in advance. btw if there is a better way to find out ips tell me. also, I know how to get peoples IPs on their own computer, but at a lan party people don't want to close a game to run ipcfg or something like it. whatever.

It's probably better to set up DDNS, so that you have working reverse lookups, and the machines will get whatever name is set, then you can just ping the name.

 

Otherwise, just run:

 

# tail -f /var/log/syslg|grep DHCP

 

and you will see all the DHCP traffic. Windows machines should normally send their name in the DHCPREQUEST

 

There are probably also some simple apps which will show you all the current leases, you may want to search on freshmeat.net
