I have about 120 machines on a off site location, with a 40mbit connection to the home office. Most of the internet usage should be connections to other companies networks via web + citrix but i know many ppl so surf the internet (Plus the usual copying between different file servers), so im wondering if i should install a proxy server for web traffic.
I have been checking out the network traffic with ProCurve Manager and i can see at times our traffic is using the entire connection but i have not been able to to see what kind of traffic or who is making the traffic ( Source IP that is).
so i was planning to the following:
1) Install a windows machine in between the ProCurv switch and the cirix thing that routes between this office and main office.
2) Find some sort of software that can monitor the traffic types and see if a proxy server would be helpfull.
3) Install proxy if that would help
On a side note this office has ppl from almost the entire world so everyone is not going to visit the same "news" page and so on.
Im wondering what kind of software would you guys recommend for checking the traffic over the 40mbit line? Im sure a lot of linux solutions exist, but im not that familular with the os. I found Capsa from the internet searching, and it seems to be able to do what i want, but its a bit overkill i think and a bit expensive for my usage ( considering im only gonna use it to check if i need a proxy )
EDIT: Spare machine is not a problem.
