New X11 trouble
I have three hosts on my home network, hosta, hostb & hostc, and I'm having connection troubles amongst some of them.
Again, your computer (buttuming it is running Linux) has its internal time, the so called system time, running on UTC which has no concept either of timezones or of Daylight...
hosta can run remote X11 applications on either hostb or hostc without issue. hosta can run multiple applications at the same time variously on hostb or hostc.

hostb can run X11 applications on hosta. hostb can only intermittently run applications on hostc. For instance, when I try to start up an xterm, running on hostc and displaying on hostb, then most of the time the start-up will fail with this message:
X connection to hostc.mydom.com:10.0 broken (explicit kill or server shutdown).
On the occbuttions when the xterm does start, then I can launch more X applications in that xterm.
hostc can't run X11 applications on either of the other two hosts.
Now, here's where I'm really confused. All three hosts have identical sshconfig files, have identical sshdconfig files, have identical ~-.ssh-config files, and have identicaletc-hosts files.
sshconfig contains:
Host * ForwardAgent yes ForwardX11 yes ForwardX11Trusted yes Protocol 2 StrictHostKeyChecking ask
sshdconfig contains:
Protocol 2 HostKeyetc-ssh-sshhostkey HostKeyetc-ssh-sshhostrsakey HostKeyetc-ssh-sshhostdsakey PermitRootLogin no X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost no UsePrivilegeSeparation no MaxStartups 3 Subsystem sftp usr-lib-ssh-sftp-server
~-.ssh-config contains:
On 12 Apr 2006, in the Usenet newsgroup comp.os.linux.misc, in article That might be pushing the numbers a bit. And Vancouver isn't that much...
Compression yes ForwardX11 yes ForwardAgent no ForwardX11Trusted yes
For a short time I had a problem withetc-hosts on hostc in that it had 127.0.0.1 listed as one of the addresses of hostc, causing me to groometc-hosts until they looked good, and look identical across the hosts.
All 3 hosts are running OpenSSH 4.3p1. hosta is a Mandrake 10.1 system. hostb is a Mandrake 9.0 system. hostc is a Mandriva 2006.0 system.
I'm thinking of going back to OpenSSH 3.7.1p2, which ran without fail ever since I installed it shortly after its release. The Mandriva 2006.0 system ran without fail with OpenSSH 4.2p1. Maybe that would be a good choice. I'd rather fix the 4.3p1 implementation tho, since it includes improved security over prior versions.
Any advice? Thanks....
