Out of no where, I can no longer download or upload anything utilizing Transmission or BitTorrent clients. Also, I decided to try the mail.app and it will not connect to either of my email servers (which are fine, setup just fine on other computers). Also, I tried thunderbird thinking it was a mail.app problem, but won't work there either. I thought perhaps I needed to check my airport extreme, but the utility app can not find it? Any suggestions on what to check? Something surely is odd. I do have little snitch installed, but looks to be OK, but perhaps I'm missing a setting. Leopard 10.5.8.
