They send BREAK on power-up so if you ever have to power cycle one you're gonna halt all of your other boxes.
manual escape to debugger on serial console not working?
Hello, While investigating a problem with one server i installed a serial console on it. The machine has a supermicro board with console redirection enabled on the same port, and everything seems ok, i.e. when the machine panics i get a debugger on the serial console, but when i try to manually escape to the debugger with BREAK (~#) i get this on the screen : The following connections are open: #0 client-session (t4 r0 i0/0 o0/0 fd 4/5 cfd -1) Manual enter to the debugger works only if i go physically to the keyboard and do a CTRL-ALT-ESC, then i get KDB: enter: manual escape to debugger on the serial console. i have this added to my kernel conf : options BREAK_TO_DEBUGGER options KDB options DDB and this in /boot/loadaer.conf : console=comconsole Maybe the fact that there is physically attached keyboard interferes with the serial console?

* Niki Denev [EMAIL PROTECTED] [2006-01-26 10:50 +0200]: to the debugger with BREAK (~#) i get this on the screen : The following connections are open: #0 client-session (t4 r0 i0/0 o0/0 fd 4/5 cfd -1) Are you using ssh? man ssh Escape Characters When a pseudo terminal has been requested, ssh supports a number of func- tions through the use of an escape character. A single tilde character can be sent as ~~ or by following the tilde by a character other than those described below. The escape character must always follow a newline to be interpreted as special. The escape charac- ter can be changed in configuration files using the EscapeChar configura- tion directive or on the command line by the -e option. The supported escapes (assuming the default `~') are: ~. Disconnect ~^Z Background ssh ~# List forwarded connections ~ Background ssh at logout when waiting for forwarded connection / X11 sessions to terminate ~? Display a list of escape characters ~C Open command line (only useful for adding port forwardings using the -L and -R options) ~R Request rekeying of the connection (only useful for SSH protocol version 2 and if the peer supports it) Nicolas -- http://www.rachinsky.de/nicolas ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

I rarely use the ssh break so I set it to something other than '~' in my .ssh/config so it doesn't clash with (eg) tip. -- Peter Jeremy ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
