Damien, Sorry about distributed context. Those discussions told me about the new ObscureKeystrokeTiming argument to the ssh command. One reply suggested I try that because it is easy to test. Most of my xterm ssh command combinations in fvwm configuration file are expressed 'Exec exec xterm -title ... -e ssh <user>@<host>' and do not have a noticable delay. One is expressed 'Exec exec ssh -Y opendev xterm -title roger@opendev', which you mention, and does have a noticable delay. It seemed far easier to find out what was going on by asking about this command rather than the formally identical 'ssh -Y <hostname> idle3.n' command: xterm is in OpenBSD base so asking a Python question on ports@ was probably too wide. It is the 'ssh -Y <hostname> idle3.n' command that worries me, and two scripts with 'ssh -vvv -Y ...' traces follow. The first is for starting idle, and the second is for invoking the open file dialogue. Adding '-o "ObscureKeystokeTiming no"' into the command gets rid of the delay: but I count this as a workaround unless told this is how the command is supposed to be done at OpenSSH 9.5 compared with OpenSSH 9.3.

The plan is to keep the OpenBSD Xserver box at 7.3 until the next upgrade of the FreeBSD 13.2 box when 14.0 is released (it's well into release candidates right now) and hope it has OpenSSH 9.4 and fixes the problem. > > > > On the FreeBSD 13.2 box 'ssh -V' says OpenSSH_9.3p1 and 'sshd -V' says OpenSSH_9.3, while both say OpenSSH_9.3 on the OpenBSD 7.3 box. > > > > I would rather not be relying on hope. > > > > Roger > > _______________________________________________ > > openssh-unix-dev mailing list > > openssh-unix-dev@xxxxxxxxxxx > > https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev > > > _______________________________________________ > openssh-unix-dev mailing list > openssh-unix-dev@xxxxxxxxxxx > https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
