Re: Monitoring ssh connectivity to a server using perl !

I like net::ping. But what's the point of reinventing the wheel? There's dozens of network monitoring suites that'll do this for you - nagios for one should suite the purpose well enough. Also, nmap should have a module to allow you to audit ssh. With any luck, you might be able to access that fro

Simple Script That Runs Under Perl 5.8 but not under Perl 5.10

The following script runs on 5.8 but does not run on 5.10. I distilled out a short program with the heart of the bug. The output of this script could be achieved easily without recursion but my real sort routine does need to be recursive, but I removed most of the code. Ignore the fact that this d

Re: Monitoring ssh connectivity to a server using perl !

Well, each new ssh connection should spawn a new process so you could look at it from that end. More technically, you could look into netstat or lsof modules. On Nov 23, 2010 11:31 AM, "Amit Saxena" wrote: > Hi all, > > What's the best way to monitor ssh connectivity, and not just ssh port > avail

Monitoring ssh connectivity to a server using perl !

Hi all, What's the best way to monitor ssh connectivity, and not just ssh port availability, to a server using perl assuming following constraints ? I tried for Net::SSH but public private key is not allowed. I tried for Net::SSH::Perl etc but these are not built in perl distribution (active per

This might be useful... __CODE__ use Fcntl qw/O_WRONLY O_CREAT O_EXCL/; open(FH, "<", $file) or sysopen(FH, $file, O_WRONLY | O_CREAT | O_EXCL) or die "can't create new file $file: $!"; __CODE__ Thanks, Chandrashekar On Tue, Nov 23, 2010 at 5:31 PM, Gopal Karunakar wrote: > Hi All, >

Check if file is open in unix

Hi All, I want to check whether a particular file (a simple text file) is open in the UNIX environment. i.e. I want to make sure that its not getting written into by some other process before my Perl process open it. So that it will always get a complete file. Is there some way of making sure
