I'm having some troubles with TTY logging. My host system is Fedora
core 4 w/ 2.6.11-1.1 Kernel.
I've downloaded and patched the 2.6.17 vanilla kernel w/ the tty patch
found here:
http://user-mode-linux.sourceforge.net/work/current/2.6/2.6.20-rc5/patch
es/tty-logging
(note I had to edit this line in the patch file:
INIT_WORK(&tty->SAK_work, NULL); to INIT_WORK(&tty->SAK_work, NULL,
NULL);
The patch goes through successfully, I run
make defconfig ARCH=um
then
make menuconfig ARCH=um
enable tty logging in the options
Run a make ARCH=um
It builds fine, I run the UML with:
./linux.final ubda=FedoraCore5-x86-root_fs mem=128M tty_log_fd=3
3>/home/new/tty_log eth0=tuntap,tap0,00:10:B5:D6:8C:B0,172.20.243.189
When I run it w/ options: tty_log_fd=3 3>/home/new/tty_log the log
appears to have a bunch of binary data in it and is pretty large after
starting up the uml instance (usually about 65kb). I see some pieces of
text, but mostly junk characters.
I stumbled upon this, when I run
./linux.final ubda=FedoraCore5-x86-root_fs mem=128M tty_log_fd=4
3>/home/thomas/new/tty_log
eth0=tuntap,tap0,00:10:B5:D6:8C:B0,172.20.243.189
tty_log_fd=4
I actually get a decent looking log(no time stamps or anything though).
However all user input is logged twice (I'm thinking it's getting stdin
and stdout) and I'm seeing shell color code I guess too.
So if the user in the uml instance runs host% ls -la the log shows
host% llss -llaa
Is this normal? Is there a way around it?
When trying to use the uml tools on the logs, the tty_log.pl and
playlog.pl give:
Short file - expected 1095114810 bytes, got 8025 at tty_log.pm line 47.
If I run playlog.pl on the large logs I mentioned above with the binary
data, it just sits there indefinitely.
Thanks for any help.
