Bot freezes after an exec

2005-04-24T08:40:22-04:00

I've tried './psybnc &' before and the bot still forze, didn't try nohup though... I'll give it a try when I feel like it

Imo eggdrop stuck because it wait until the exec will return somethink.. Or until the executed proces will go to background or will end..
Maybe i'm wrong.. You could also try ./psybnc &(but..if you log out, your background task might get killed automatically).. Just some sugestions ;)

Code:

NAME       nohup - run a command immune to hangups, with output to a non-ttySYNOPSIS       nohup COMMAND [ARG]...       nohup OPTIONDESCRIPTION       Run COMMAND, ignoring hangup signals.       --help display this help and exit       --version              output version information and exit

what was the signal hangup (kill -s SIGHUP " to do with a prozess causing a blocking behavior? I somehow doubt the prozess causes the stuck because it recieves the signal hangup .

I'm not sure..
I think nohup should do the job..

catch {exec sudo su Fz -c "cd $mydir/psybnc;nohup ./psybnc"} error

The comany's owner is going to make a bash command on the shell, so all I have to exec is the command user and pass. That should fix the problem. Thanx

Bot freezes after an exec

2005-04-18T15:37:51-04:00

Code:

catch {set this [set yo [open "|sudo su Fz -c "cd $mydir/psybnc;./psybnc"]][close $yo]} error

i hope it is
[open "|sudo su Fz -c "cd $mydir/psybnc;./psybnc""]
the code above would be missing 1 close quote ^^

but besides this... very strange. If you believe the sudden close could cause the chield termination, you could try to "softly" close it via:
fconfigure $yo -blocking 0
fileevent $yo readable "close $yo"
but probably the error occurs while "open" is execute, so I think it would be unlogical to help ^^

Code:

catch {set this [set yo [open "|sudo su Fz -c \"cd $mydir/psybnc;./psybnc\"]][close $yo]} error

returns "child process exited abnormally" in error and will not do the job.

Code:

catch {exec sudo su Fz -c "cd $mydir/psybnc;./psybnc"} error

does the job, but the bot freezes.

as said, to avoid freezing you have to use the non-blocking open. exec will always be in blocking mode.
you can addionally use catch {open ...} to ignore any returned errors.

I've managed to find the proper command, but now my problem is that using open I get the following error:

child process exited abnormally

while using exec, the command works but the bot freezes. Any ideas on how to handle this ?

I noticed that the command I'm issuing isn't correct, I tried 'pwd' it gave the directory the bot's in nomatter what user I specify. So, until I figure out which shell command to use, we'll see if it works

thats only natural, because the cd command in your exec/open line only changes the path for the current instance of bash (or better sudo in this case). thats why I suggested to really change the bots current directory .

Try:

.tcl exec sudo su Fz -c "killall -9 psybnc && cd ../psybnc && ./psybnc"

i cant really tell you why, but you could try to split the killall and ./psybnc into 2 open queries and use the cd tcl command to change the dir (better change it back afterwards with the backup made by pwd ^^), would be probably slower, but it would at least track down the error source, if still doesnt want to work .

tried:

.tcl set this [set thisis [open "|sudo su Fz -c \"killall -9 psybnc;cd ../psybnc; ./psybnc\""]][close $thisis]

This only killed my psybnc but didn't restart it. The bot didn't freeze though. What's the reason behind this ?

hmm, probably the opened console doesnt close when psybnc switchs to background. haev you tried to use open | instead and just close the open console forcefully? Can't garantue it won't leave shadow consoles running somewhere in the memory ^-^.
