[Bug 300151] Re: ssh slow during logon, when ENTERING INTERACTIVE SESSION
I think that I have a track. Based on similar su problems, I decided to explore the possibility that it is the fault of dbus. Based on results below, I believe it to be the case and I reassign this issue to dbus. Restarting dbus fixes this issue. So I did: 1) time how long ssh to localhost takes: ==time ssh localhost date Thu Nov 20 22:55:54 CST 2008 real0m0.248s user0m0.000s sys 0m0.004s 2) Restarted dbus as root: root:~ ###/etc/init.d/dbus restart * Stopping System Tools Backends system-tools-backends ...done. * Stopping bluetooth ...done. * Stopping Hardware abstraction layer hald ...done. * Stopping system message bus dbus ...done. * Starting system message bus dbus ...done. * Starting Hardware abstraction layer hald ...done. * Starting bluetooth ...done. * Starting System Tools Backends system-tools-backends ...done. (this killed gnome-panel and stuff also, no biggy) 3) tried ssh again: ==time ssh localhost date Thu Nov 20 22:56:06 CST 2008 real0m0.268s user0m0.000s sys 0m0.008s So restarting dbus fixed this issue. ** Also affects: openssh Importance: Undecided Status: New -- ssh slow during logon, when ENTERING INTERACTIVE SESSION https://bugs.launchpad.net/bugs/300151 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 300151] [NEW] ssh slow during logon, when ENTERING INTERACTIVE SESSION
Public bug reported:
I am using a Ubuntu Intrepid 32 bit server with all latest patches.
Logging on via ssh (USING KEYS) is incredibly, painfully slow.
I have done some investigation.
1. Slowness is mild after a reboot and, as time goes on, it becomes
progressively slower and sloowweerr and ssslllooowwweee.
2. If I run ssh -v, then I can see that the ssh process is stuck for
many seconds after saying entering interactive session.
3. This even happens if I do, from that server, a command ssh
localhost.
4. Disabling GSSAPI authentication, as well as saying UseDNS no, in
sshd_config, does not help.
5. A similar problems applies to use of su and can be more easily
debugged. If, as root, I say su - username date, it is also
incredibly slow. If I debug that with
strace -o q -f su - myuserid date
then I see that su tries to connect to UNIX socket
/var/run/dbus/system_bus_socket, and then it is stuck doing poll(),
which remains unfinished. Not sure if it is related, but it could be.
