RSH Timeout
Hi All
I have a nice little script that i have written in Perl, in it use RSH ( yes i know it is i should being using ssh, but it i secure network it is being run on) the idea of the script it that it will RSH into a machine and then follow out a command, the problem i am running into is if the RSH deamon for what ever reason as stopped working on the machine, the script will keep trying to accsess the machine for a few mins and then move onto the next, is there a way to add a timeout, so if the connect is not made in say 30 seconds it will move on
thanks
John

hi,
i have many ksh shell scripts running "rsh" command and sometimes the remote host doesn't answer so the rsh command doesn't return data and the script waits.
How can i modify this to have a forced return to continue my script , a kind of controlled timeout ?
thanks in advance... (0 Replies)

LEARN ABOUT PHP
set_time_limit
SET_TIME_LIMIT(3) 1 SET_TIME_LIMIT(3)
set_time_limit - Limits the maximum execution time
SYNOPSIS
bool set_time_limit (int $seconds)
DESCRIPTION
Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 sec-
onds or, if it exists, the max_execution_time value defined in the php.ini.
When called, set_time_limit(3) restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25
seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out.
PARAMETERS
o $seconds
- The maximum execution time, in seconds. If set to zero, no time limit is imposed.
RETURN VALUES
Returns TRUE on success, or FALSE on failure.
NOTES
Warning
This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing
the time limit in the php.ini.
Note
The set_time_limit(3) function and the configuration directive max_execution_time only affect the execution time of the script
itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(3), stream
operations, database queries, etc. is not included when determining the maximum time that the script has been running. This is not
true on Windows where the measured time is real.
SEE ALSO
max_execution_time, max_input_time.
