RE: [cobalt-security] No telnet on saturdays??

["Ervin Tarkhanian" <ervin@xxxxxxxxxx>]

Hi Robbert,

I spoke with my provider, and the ports in question should be open.  Even if
this was the case, that would not explain why other ports open up.

I'm wondering if anyone else has experienced anything like this before.

TIA
Ervin.

Where are your servers located ??? If you use for example datapipe in the US
they closed some ports for security reasons. Perhaps other colocation
providers did the same.
