I am quite sure that this is a problem introduced in OpenSSH v2.5 or earlier. When I upgraded a FreeBSD 4.2 box from OpenSSH v2.2.0 to a newer version (I don't remember exactly which one now) I noticed this stalling which had never appeared before. If I used SSH Inc ssh-2.4 there was no stalling. It's not FreeBSD-specific either: I am trying this now on a NetBSD 1.5.1 that has OpenSSH v2.5.2 and if I do ten ls -l as fast as I can, I get 14 retransmitted packets and stalling. If I try the same with SSH Inc ssh-3.0.0 I get no retransmitted packets. Strangely enough I get no stalling on either sshd if I cat a 3 megabyte text... -Tomas To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
