Bug#283107: kernel-image-2.4.27-1-sparc64-smp: telnet-connections to some hosts fail
Package: kernel-image-2.4.27-1-sparc64-smp
Version: 2.4.27-1
Severity: important
After upgrading one of our Ultra 2 from woody to sarge telnet-connections
to some hosts fail with kernel-image-2.4.27-1-sparc64-smp.
Here is what I get with kernel-image-2.4.19-sun4u-smp fom woody:
---------------------------------------
raoul@dns1:~$ telnet m-nas1
Trying 188.1.74.38...
Connected to muenchen-nas1.shuttle.de.
Escape character is '^]'.
(m-nas1.shuttle.de) Enter password:
Incorrect password.
(m-nas1.shuttle.de) Enter password:
Incorrect password.
(m-nas1.shuttle.de) Enter password:
Authentication failed. Closing telnet session.
Connection closed by foreign host.
raoul@dns1:~$
---------------------------------------
With kernel-image-2.4.27-1-sparc64-smp I get:
---------------------------------------
raoul@testsparc:~$ telnet m-nas1
Trying 188.1.74.38...
Connected to muenchen-nas1.shuttle.de.
Escape character is '^]'.
(m-nas1.shuttle.de) Enter password:
---------------------------------------
After that the session is 'frozen'. It's not possible to type
anything else than '^]' and make the telnet-client quit the session.
Could it be related to the known problems with the onboard 100 Mbit/s
interface on these old SBUS-Ultra-2s? If I use an 10 Mbit/s sbus-card
everything works fine.
Also this problem does not show up on our other Ultras (which all have
only 10 Mbit/s interfaces).
I have attached tcpdump-output for both kernels to this email and hope
that this gives someone any idea what's going on.
I'd be happy to help in testing kernel-patches...
Thanx for any help
Raoul
