Under System --> Preferences there is an option called "Network Proxy" where you can set the proxy that is used by most applications. This includes the package management tools.

Have you mount your network devices?

System -> Administration -> Networking

Yeah.The firefox works perfectly. But I can not download package information from or other sites.
And in System -> Administration -> Network Tools

I tried to ping, but packets losses is 100%.

Somehow ubuntu setting proxy isn't so easy, what I find so far is
To synaptic PM, setting the system/preference/network proxy works for me
To use terminal such as apt-get, you need set proxy in bash shell,
add a line export http_proxy='proxy address' into ~/.bashrc, for example, if the proxy is http proxy, it will be 'http://proxy_address:proxy_port'

I haven't figure out how to get the proxy working for dictionary and im (pidgin/gaim) at work.

good luck!

For pidgin i use the tsocks application, and it works fine (apt-get install tsocks, then edit the /etc/tsocks.conf file, the run the pidgin this way: tsocks pidgin)

Tsocks homepage is:

@Lorant: Do you use the standard version of tsocks? Any custom settings?

I find that launching `tsocks pidgin` causes my CPU usage to hit 100% until I close pidgin. I think it's some sort of DNS leaking issue or something, I'm not sure. Pidgin invariably causes my SSH tunnel (dynamic port forward for a SOCK proxy) to lose connections.

Can you help with this problem?
