Blocking ports
Tuesday, July 11, 2006
Working in the Autonomous University of Guadalajara….
Why does anyone find it necessary to block any port other than 25? I mean I’m grateful that I’m able to access the network at all, but why do they find it necessary to block access to AIM, iTunes downloads, podcast downloads, etc? I just don’t see how it’s necessary when they’ve got sufficient bandwidth.
The hotel we’re staying in blocks port 25…understandable. Their wireless network is completely open with no passwords so spammers could go crazy. My solution was simply to open an alternate port for smtp connections to my own server and to use that. Alternatively, I could have created an ssh tunnel to port 25 on my server, and that would be more secure, but more trouble.
Stupid—I can’t update my podcasts or communicate with my students…
