[E3-hacking] Running an IRC bot on the E3

Hi, I'm something of a Linux newbie so be generous. :) I'm running busybox on my E3 as per the wiki and I also have a Pegasus USB Ethernet adapter working with a static IP on my LAN.

Can anyone tell me: - What is the command to auto-configure the E3's IP address via dhcp? - Can I turn off the E3's LCD screen and just enter commands via telnet? - How can I compile and run Energymech (an IRC bot)? - How can I run dircproxy (a caching IRC proxy server)?

In the case of dircproxy, I already transferred an ARM binary to the E3 via wget, chmod 777 and tried to run it, but I just got a 'permission denied' error.

Would be grateful for any info. Thanks :)
