Finger? Who still uses Finger these days? I haven't seen that since my college Unix lab days. Glad they killed that one off too.

Haha, I bet the network admin is feeling pretty smug about this one. 'No more bootp server for you, network devices!' *cracks knuckles*

Wait, they disabled SNMP too? Oh no, how am I going to remotely monitor the router now? Time to break out the CLI, I guess.

Looks like the code disables some basic services on the router. BootP, DNS, and NTP are all turned off. Good security practice to limit exposed services.
