Hello,
After making a connected socket to a tcp server, how to implement the
read/write more than once?
for example:
1) make socket connection
2) write a command to socket
3) read the result from remote server
4) write another command to socket
5) read the corresponding result again
6) write...
So write the code like:
unlink $file or die $!;
This will throw up an error message and die.

Yes. All Perl functions that interact with the underlying system will
set $! on failure. ($! is the same as errno in C.)
man 3 errno

Hi,
Can anyone tell me hoq to write a regular expression which matches
anything _except_ a litteral string ?
For instance, I want to match any line which does not begin with
Nomatch. So in the following :
Line1
Line2
Nomatch
Line3
Line 4
I would match every line except

was a problem with the Net::SNMP module. Sorry for the same.
I have one more doubt. Is there any tool, which i can use for automatically
converting this strings to OIDs.

Is it correct ?. Can i replace the string with this decimal values ?.

I should first note that you've placed a one line separator between each two
consecutive lines which makes your message harder to read.
