Comment 1 Mark Watts 2009-09-29 06:07:59 EDT
This problem "goes away" with Fedora 11 - openssh-clients-5.2p1-1.fc11.i586 so backporting this version to F10 would probably do it.
Comment 2 Bug Zapper 2009-11-18 07:15:56 EST
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Re-opening, its back again on Fedora 12. $ rpm -q openssh-clients openssh-clients-5.2p1-31.fc12.i686 $ ssh netscreen@ssg-140 netscreen@ssg-140's password: Remote Management Console ssg-140-> buffer_get_ret: trying to get more bytes 4 than in buffer 0 buffer_get_int: buffer error
Comment 4 Jan F. Chadima 2010-03-16 12:44:00 EDT
can you test the latest version openssh from f-13? there is openssh-5.4p1 which has rewritten the transport layer and message multiplex.
Comment 5 Mark Watts 2010-03-19 10:29:24 EDT
OK, I still see the same issue with openssh-clients-5.4p1-1.fc13.i686.rpm However, I think it may be related to the following section I have in my users ~/.ssh/config file: Host * ServerAliveCountMax 4 ServerAliveInterval 15 As another user (root in this case) I do _not_ see the disconnect, so I think I've actually found a bug in ScreenOS on Juniper firewalls, not a bug in SSH itself. As a result, I'm closing this again.
