[twsocket] Whick ports are required for TFTPClient
Hi, Allowing port 21 through my router when using TFTPClient caused a data error when attempting to send a file. Allowing port 20 cured this. Sniffing the net showed that 22 has worked in some cases. Also, there is a difference between active and passive in terms of the extra port used. Can TFTPClient just use the one port? I am sure that I normally only need to open port 21 at the router for things like CuteFTP. ...Andy -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Whick ports are required for TFTPClient
Hello Andy, If you are behind a router then you have to switch to passive mode. This means that the FTP server will listen on another port for the data transfer and the client will then connect to that port. In normal mode the client will listen on another port but blocked by the router. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Friday, February 8, 2008, 12:29, info2004 wrote: Hi, Allowing port 21 through my router when using TFTPClient caused a data error when attempting to send a file.

Hello Andy, Addition to what Wilfried said, if your router is unable to parse the contents of the PASV command response, (in cases like stupid router or SSL), you need to define a manual pasv port range and forward up to 5-6k ports from your router. These are the ports that the client will connect to when transferring files or folder listings, in PASV mode.
