[Planetlab-users] FW: TCP RST automatically sent after TCP SYN

[Chan Edmond]

Hi,Besides, I have just tried my another TCP tool in a PlanetLab node to establish the three-way handshake with the same server. The tool worked fine half an year ago under a few PlanetLab nodes, but now it fails and the PlanetLab resets my TCP connections right after the SYN/ACK arrival. I have verified that both programs follow the example C code from the Planetlab VNET guide for creating and binding the TCP socket. Any ideas? Thanks.Edmond ChanFrom: renewman82 at hotmail.comTo: users at lists.planet-lab.orgSubject: TCP RST automatically sent after TCP SYNDate: Mon, 20 Aug 2007 11:45:51 -0400





HI,I have written a program to establish the TCP three-way handshake with a remote server "B". It works fine from my testing machine. But when I ran it from a PlanetLab node "A", I got the following packet trace captured using libpcap 0.8.3:NO.     TIME         SRC        DST   INFO1         0.000000   A            B        SYN2         0.120004   A            B        RST3         0.119988   B            A        SYN/ACKshowing that a RST packet is automatically sent *after* the SYN/ACK arrival according to the captured time. Any ideas? Thanks.Edmond Chan¥Î¬Ûï¡B³¡¸¨®æ¡B²M³æ¡B¯d¨¥ªO¥´³y¦Û§Ú³Ð·N¤À¨ÉªÅ¶¡¡AºÉ±¡ÄÀ©ñ¯u¤uªº§A ¡X Windows Live Spaces
