I also see this problem, between openssh on RedHat 7.2, and a Datafellows SSH2 server on IRIX. Furthermore, I received reports from a user that using ssh to connect to a CVS server now also stalls. I can reproduce the problem 100% with using ssh to pull a remote CVS repository (i.e., using CVS_RSH=ssh, and using an :ext:<host>:<path> address). The file in question is approximately 10 MB. CVS *always* stalls at this point, somewhere between the first 100 and 300K. The exact stalling point seems to be random. The -q and -v options made no difference. I tried it with different kernel versions, same problems. I compiled OpenSSH 3.1p1 from source with gcc 2.96 and gcc 3.0.4, same problems. Only compiling OpenSSH 3.0.2p1 from source made the problems go away. This makes it look increasingly likely that the cause is a bug in OpenSSH 3.1, plain and simple. Unfortunately, it is a showstopper type bug for me. I just installed version 3.1p1-3.i386.rpm, and the problem SEEMS to be fixed. At least I could download files that I could not download yesterday. Jon Baron I can also reproduce similar problems: - I experience frequent stalls when I log from a Red Hat 7.2 + openssh-3.1p1-2 client into an OpenLinux-2.4-7 + openssh-2.3.0p1-2 server and tunnel Perforce (a CVS-like commercial program) and HTTP. - I havne't seen that when I log from the same Red Hat 7.2 + openssh-3.1p1-2 client into a Red Hat 7.2 + openssh-3.1p1-2 server and tunnel Perforce. I am stracing ssh and should be able to provide a stack trace and an strace trace next time SSH hangs. I can't produce a stack trace as I don't know how to debug a program with SUID set. Debugger won't attach to such a process. I can show strace output though. I don't know how to attach it to this report. Tell me how to send it if you believe it can help. I also should be able to provide verbose openssh output if it helps. This bug could be a duplicate of 40912, or at least it may be related. Please test with the current Fedora Core. For me this has not been a problem for quite a while (with FC3). I forgot about it. OK, thanks. |
