Good Evening,

I have a functional Net::SFTP program, however, Net::SFTP->new(...) does not have a built in TIMEOUT parameter.

I have not used $Sig{ALRM} before. After researching / reading ALOT of resources I have hacked the following code.

What I want to do ... Capture a no-response situation from the remote host after XXX seconds, notify user of error (page, email) and end program.

Are there other situations that my example may not be catching ?

Is there a better use of $SIG{ALRM} when compared to my example ?

#notify user attempting connection
writeLog( "Connecting to host : $host as user : $user" );

#open connection
eval { #timeout if no response within 120 seconds
    $SIG{ALRM} = sub {die "Net::SFTP timed out\n"};
    alarm(120);
    $sftp = Net::SFTP->new($host, user=>$u password=>$p debug=>1);
    alarm(0);
};
if ( $@ ) { #handle error opening connection
    alarm(0);
    chomp( $@ );
    writeLog( "Error: $@ trying to connect to remote $host");
    sendEmail();
    sendPage();
    die("\n");
}

alarm(0);

writeLog("Connected to host : $host as user : $user");
