TnClient is behaving the same strange way. TnClient displays: "Connecting to xxx.xxx.xxx.xxx" and then "Connected" but the welcome banner of the server is displayed with 20-30 secs delay. On the other machine, the welcome banner is displayed right after "Connected".
My gues is it can be an OS bug, on the specific hardware platform (ethernet NIC, etc.). I've downloaded a packet sniffer, and 3 packets are captured when the connection is initialized: one from the client to the server, one from the server to the client and again, one from the client, and then the data transfer is delayed. The server is build around ucspi-tcp from http://cr.yp.to, on linux. On short, the "tcpserver" program is listening on a specified port and when a connection is established they launch an external program, rewriting input/output filedescriptors of that program on the incoming socket. It works very well, as it is also used for the (*nix users wellknowed) "qmail". 10x again, / Ionut Muntean -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Francois PIETTE Sent: 6 decembrie 2005 07:56 PM To: ICS support mailing Subject: Re: [twsocket] Strange > The telnet connection on the specified port on the server is working well. > :( OK, so let's try with one of the ICS provided demos so that we are sure you have not a bug in your own code.
