couldn't establish connection to remote target: kgdb
Hi, I'm facing an issue of not being able to connect to the target from the host on i386 on 6.2-RELEASE. I get a Couldn't establish connection to remote target, everytime. 1) Yes, both the baud on source and sink is 9600, confirmed doing a tty -a -f /dev/cuad0. 2) and /etc/ttys has ttyd0 and ttyd1 both turned off for getty. 3) i even did a cat /dev/cuad0 and echo hello /dev/cuad0. and I get the characters on the other side correctly. configured kernel with GDB, KDB, DDB. and started kgdb like this kgdb -r /dev/cuad0 kernel.debug. and I get : Ignoring packet error, continuing... Couldn't establish connection to remote target malformed response to offset query, timeout. Can some-one, a hacker will have encountered such situations, please answer my dilemma.

kgdb in emacs
Hi, I'm trying to use kgdb in emacs on Freebsd V6.2. I'm able to use kgdb on the command line like this kgdb -r /dev/cuad0 kernel.debug. In 6.2 there is no gdb -k, only kgdb. But when I run it in emacs. M-x gdb Run gdb ( like this ) : kgdb -r /dev/cuad0 kernel.debug I get : Current directory is /dev/ kgdb: multiple core files specified. Ignored kgdb: d: No such file or directory. Debugger exited abnormally with code 1 Why is emacs even interpretting my commands. Why doesn't it just call kgdb with whatever arguments I give ?

synchronous freebsd print
Hi, I have a quick question, and I believe this will be a common requirement. I do a print of some data and then immediately in a next statement there is a crash. But the print is not complete, before it completes there is a crash, the print is about 6-9 lines . Is there anyway to get the complete print before executing the next instruction. like putting a delay before executing the next instruction.

Re: synchronous freebsd print
This is a standard C question. Sorry, if this clarification is too simple, but I thought freeBSD kernel implemented its own print function. and the man for fflush says it is in the standard C-library. and the kernel source has no defn for fflush. I saw lots of kernel related questions asked in this list, so I posted my question here. Please correct me if I am wrong. and Yes in the kernel code I have a \n at the end of my print, still the print is not complete and the line next to it that causes the crash does not give the result I want. Is this a common scenario or am I doing something wrong. Sanjeev.

seemingly good gdbinit for freebsd kernel errors out
Hi,
Im trying to debug a gdb init script that errors
out saying: too few arguments in function call
Here is the script
define kldload
set $kld = linker_files.tqh_first
set $done = 0
while ($kld != 0 $done == 0)
if ($kld-filename == $arg0)
set $done = 1
else
set $kld = $kld-link.tqe_next
end
end
if ($done == 1)
shell /usr/bin/objdump -h $arg0 | \
awk '/ .text/ { print set \$offset = 0x $6 }' .kgdb.temp
source .kgdb.temp
add-symbol-file $arg0 $kld-address + $offset
end
end
document kldload
Loads a module. Arguments are module name and offset of text section.
end
Any thoughts ?
Thanks,
Sanjeev.

Saving entire console sessions
Hi, Is there any way to save entire console sessions ? Screen asks me to copy and paste what I want. I don't want to do that I need to save entire sessions. like a start till I do a exit or quit the application. Is there a utility like that ?
