Shell accounts, advantages:
1) A shell account allows you to examine your networks from the other side
of the router (the internet) while being on this side of the router.
2) Access to compilers and other programs, and to bitching hardware. If you
are a student, with no computer, a shell account gets you compilers and
other tools. I'm a sys op for an ISP with a multi-city MAN and WAN. A
bitching Linux box, dual P III with a gig of memory came with the small ISP
we acquired recently. I often use a shell and ftp to upload and run big
builds and other jobs, it will do them in less than half the time the local
servers would take.
3) SSH and others make a remote shell reasonably secure.
4) Remote shells mean I can telnet into the servers from home and fix things
while still
in my PJ's. I can check my mail anywhere in the world I can get a telnet
session. I can fix things at night so I am not pounded by user complaints in
the AM.
