I am facing same issue on bsnl . visited bsnl exchange today . J.E / J.T.O replied that yes they read ssh/sftp in books but they don't know how to block unblock these ports . what the hell is going with digital India. what the bloody f**k
This is Rajakumar from Karnataka, 6 years user of BSNL.
All of sudden i got this issue and surprised to see the same working in other connections.
Wasted lot of time to check all the VPS.
No idea about the Geevi who taken the decision.
But definitely they need to reconsider.
This could be against net freedom to block a commonly used port.
They may have the rights to control the inbound,
but for sure they are not in the position to decide which port i am connecting outbound.
Sadly today Facebook even isn't working !
