You could also try connecting to the server IP in question via telnet. $ telnet 64.233.167.83 443 Trying 64.233.167.83... Connected to 64.233.167.83. Escape character is '^]'. Replace the 64.233.167.83 with whatever IP you're box is trying to reach. If you see "Connected to IPADDRESS" that means it is not a network issue as you made a successful TCP connection to the server. If you see "Connection refused" that probably means the server port is closed (server is not listening) though some filters/firewalls can fake this. If you see "Connection timed out" or if it just hangs forever that means there is probably a filter/firewall blocking it or there is no server at that IP address at all. If you use something like wireshark or tcpdump you can watch and see if there are any replies and what they are. Most likely your ISP is not blocking outbound TCP/443 traffic. In any case if you're sure your own local stuff is not blocking anything find the IP/hostname of the server you're connecting to and then contact the administrator of the server and/or vendor of the software and ask for assistance. -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of John Gateley Sent: Friday, June 27, 2008 1:03 PM To: bradyh at bitstream.net Cc: tclug-list at mn-linux.org Subject: Re: [tclug-list] problem with port 443 connection On Fri, 27 Jun 2008 12:48:25 -0500 (CDT) bradyh at bitstream.net wrote: > I'm trying to play Penny Arcade: On the Rain-Slick Precipice of Darkness > (which has a Linux version for anybody interested in such things.)

Try WireShark to sniff the connection, that may (or may not) provide clues. If it is really blocked, you'll see outgoing SYN packets with no responses (assuming it is 443 TCP, if it is UDP, that's different). If it isn't blocked, it won't help much - the traffic is probably encrypted and so you won't be able to make sense of it. j -- John Gateley <tclug at jfoo.org> _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota tclug-list at mn-linux.org http://mailman.mn-linux.org/mailman/listinfo/tclug-list
