[R] Ports

[Thomas]

I realise this isn't exactly an R query, but does anyone know what  
ports I need to open in order to get the install package function  
working? It's blocked by our University firewall.

I have been asked for the following info and I don't know where to  
find it or how to get it. I guess my computer knows this info - it  
knows where it's trying to connect to - but I don't know how to get at  
it.

Source IP addresses (I know this one)
Destination IP addresses
Protocols and ports

Any advice/info appreciated.
