Hello,
Thanks for this tip. First I could not identify any traffic on port 9100. While the tests on ports 110 and 25 repeatedly showed up, there was no activity at all on port 9100. After a reboot of the monitoring server, activity on port 9100 was detectable. (If a test is not run, it would be good to indicate that rather than displaying OK.) The packet data is ^] and the roundtrip time exceeds the specified timeout of 60 s. After a while the telnet checks to that port stop again and only the pop and smtp tests can be seen in the packet sniffer. Is it possible that SA gives up on running telnet tests under certain conditions ? The full version is SA 6.2.2333 Thanks, Rainer JOCHIM | Web Development | www.soleica.ca (http://www.soleica.ca/) 4472-B Saint-Denis, Montréal, Québec, H2J 2L1 tel: 514-495-0373 | fax: 514-495-6570 Pensez à l’environnement avant d’imprimer ce courriel / Consider the environment before printing this e-mail.

In that case telnet via command line was right: the checked device had been taken down for testing. When the device is up, telnet can connect.

And that this firewall allows connections done by certain apps only? ----- Original Message ----- From: Rainer Jochim (mailto:[email protected]) To: Servers Alive Discussion List (mailto:[email protected]) Sent: Thursday, July 08, 2010 10:45 PM Subject: [SA-list] False "Connection possible" result Hello all, We run a telnet check to an IP on port 9100. Servers Alive 62 returns “Connection possible”. Running the command manually on the same machine (Windows Server 2003) returns “Connecting to... xyz... Could not open connection to the host, on port 9100: Connect failed” Why would Servers Alive not return an error in that case?
