I have three BSD machines running 6-Stable, all of them only recently upgraded from 5-STABLE. Ever since the upgrades, I cannot get remote hosts to which I've ssh'd to connect to the tunneled X server. For example: hostb> ssh -X hostA hosta> echo $DISPLAY localhost:10.0 hosta> xev Xlib: connection to "localhost:10.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key xev: unable to open display 'localhost:10.0' hosta> exit hostb> ssh -Y hostA hosta> echo $DISPLAY localhost:10.0 hosta> xev Xlib: connection to "localhost:10.0" refused by server Xlib: Invalid MIT-MAGIC-COOKIE-1 key xev: unable to open display 'localhost:10.0' If hosta is not a FreeBSD machine, the *OPPOSITE* attempt works fine. For example, if hosta is my linux laptop: hosta> ssh -X hostb hostb> echo $$DISPLAY localhost:10.0 hostb> xev [... xev starts up just fine and displays on the laptop...] But if the machine from which I'm sshing is one of my 6-stable BSD machines, it never works. All the 6-stable machines are running the latest ports, as I keep my ports tree csup'd and portupgrade regularly. I've googled the issue and the only thing I ever find is people answering "you should use -Y instead of -X to enable 'trusted' forwarding." This clearly doesn't work for me, either. Since I am not seeing tons of recent references to this all over the net, I am pretty much concluding that I must have some kind of configuration mistake on my BSD machines' X or ssh setups, but I don't immediately see one. I thought I left my sshd config pretty much as it was out of the box, but perhaps I screwed something up. Can anyone suggest a place to start looking for the error? -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 AHTB#1 http://kevan.org/brain.cgi?DDTNM "And, isn't sanity really just a one-trick pony anyway?
