SSH: Corrupted MAC on input

[Vishu]

hi Guys,

While doing login through SSH, i am getting the following error.

Password:
debug1: Authentication succeeded (keyboard-interactive).
debug1: Login completed
debug1: Cleanup PKI subsystem
debug1: PKI_DestroySession called. Session id: 1130489669
debug1: PKI_Cleanup called. Reference count: 1

debug1: channel_free: channel 0: client-session, nchannels 1
debug1: Calling cleanup 0x40daa0(0x0)
Connection Failure.

Telnet/ftp is working very fine.

Please suggest on it.

Thanks

Hello,

a) The Corrupted MAC is a checksum. It is a
more accurate than the standard TCP checksum.

That means you have a data corruption
somewhere. Some culprits to investigate:

* Firewall;
* Network address translation;
* Network congestion;
* Network device driver;
* NIC settings (speed, duplex mode,...);
* NIC faulty;
* Switch/router;
* Something else that corrupted the
data between the two SSH clients.

b) You did not specify the version of
HP-UX, the SSH client you use (is
it by any chance putty?), and SSH version
itself.

There are buggy versions of SSH too.

Cheers,
