Normal workload, X-windows, a few xterms, editor, mozilla, etc. (host A) I have a NFS/SAMBA-mount (both show the problem) to host B. Host B runs 2.4.19rc5aa1. I can get a xterm, in which i have a ssh-connection to a third host C 'stuck' by simply cat'ing a large file from the NFS/SAMBA server to /dev/null. The xterm/ssh seems stuck, that is no key i press is received on the other end, but output of the program running on host C is updated in the xterm. I checked with tcpdump: the keypress does not generate a packet, my host only sends ACK's on that ssh connection to host C. The ssh-connection is not unstuck by stopping the data transfer from host B. I checked that plain 2.5.42 and 2.5.43-mm1 do not have this problem: here my input goes through to C. At least for small amounts of input, i did not test anything beyond typing a few hundret chars. recap: "mount /mnt/hostB" "ssh hostC" -> type random stuff in that connection at the same time do "cat /mnt/hostB/bigfile > /dev/null" ssh gets stuck. hardware: PIII/600, 3c905B on 10baseT half-duplex I'm sorry i cant do any further checks until Friday afternoon (MET). /B. --------------- quote ends --------------- --=20 Sebastian Benoit My mail is GnuPG signed -- Unsigned ones are bogus -- http://www.gnupg.org/ GnuPG 0x5BA22F00 2001-07-31 2999 9839 6C9E E4BF B540 C44B 4EC4 E1BE 5BA2 2= F00 Oxymoron #633: Mutual Differences --WIyZ46R2i8wDzkSu Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iEYEARECAAYFAj2v5rUACgkQTsThvluiLwCu1QCgi38mkGpDNKO8kw/N1BWikRsg HR0AoIKi8Mfuf/7X27opcDoedwFOn1JN =rhqg -----END PGP SIGNATURE----- --WIyZ46R2i8wDzkSu--
