| Nov 26, 2014 at 19:48 | comment | added | Magnus | But how do you know whether the connection was blocked at the server end or at your own originating end (perhaps you're behind a firewall when you test)? | |
| Jan 14, 2014 at 23:40 | comment | added | KC Baltz | What if you don't have perms to install telnet? Is there another standard tool? | |
