Re: [twsocket] abnormal winsock behaviour by firewall
10053 is connection aborted. I guess Norton is listening on all ports and abort the connections he is configured to deny. -- [EMAIL PROTECTED] Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) http://www.overbyte.be - Original Message - From: Wilfried Mestdagh [EMAIL PROTECTED] To: twsocket@elists.org Sent: Friday, September 16, 2005 11:09 AM Subject: [twsocket] abnormal winsock behaviour by firewall Hello, Just information because I think this is interesting to know: Normally when I want to know if there is a server on a machine I try to connect on the port where it should listen and check Error argument in OnSessionConnected. If you do this on a machine where Norton antivirus is running, and you try to connect on port 'smtp' and there is _no_ server and 'mail checking' is checked in the antivirus thing then OnSessionConnected will fire without error and a while later OnsessionClose will fire with a 10053. So dont just rely on the winsock error in OnSessionConnected :( -- Rgds, Wilfried http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] multiple nics and broadcasts
This is a question about how to deal with multiple nics and broadcasts. If I had a computer (A) with multiple nics listening to broadcasts, with each nic attached to a separate network. And then I had another computer (B), on one of those networks, send a UDP broadcast. Can computer (A) determine which of its IP addresses intercepted the broadcast? Thanks, Kenny __ Yahoo!

Can computer (A) determine which of its IP addresses intercepted the broadcast? If every nic has 1 IP, you can bind an udp socket to each IP, listening on the port to which you're sending broadcasts. So you'll end up with a TWSocket for each nic. There could be a better solution, tough. -- Marcello Vezzelli CTO Software Development Department E-Works s.r.l. tel. +39 059 2929081 fax +39 059 2925035 Direzionale 70 - Via Giardini 456/c 41100 Modena - Italy - La presente comunicazione, che potrebbe contenere informazioni riservate e/o protette da segreto professionale, è indirizzata esclusivamente ai destinatari della medesima qui indicati.

[twsocket] SocksServer. Host name resolving.
Hello all! Using TWSocket, when the connection is established via SocksServer, is this possible to specify whether the address of destination host is resolved on the client system or passed to SocksServer for resolving? Currently, if I understood correct, the host name is always resolved on the client system, but sometimes the local policies can forbid local DNS operations.

Re: [twsocket] abnormal winsock behaviour by firewall
Hello Francois, 10053 is connection aborted. I guess Norton is listening on all ports and abort the connections he is configured to deny. Yes I think so too. I think this is totally wrong, most other firewalls give a 10060 (timeout) whitch is also wrong, but at least is gives a TCP connection a more or less normal behaviour. Norton let's you connect without error which is very abnormal, so I hereby clasify the product as 'not good' :) --- Rgds, Wilfried http://www.mestdagh.biz -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
