We tested by using either pop3 cleint or a direct telnet pop3 login. we looked at the tcpdump, the telnet side strangely send the RST to pop3 server without a clear reason (at the end of the following pop3 output), other pop3 msgs downloading works, except this particular msg, whihc always knocked out the connection. is there any known strangeness out of the tcp stack? 17:07:15.096321 s2.my.net.3290 > ant.POP3SERVER.pop3: P 3334678991:3334679000(9) ack 1566293258 win 57920 (DF) [tos 0x1 0] 17:07:15.096459 ant.POP3SERVER.pop3 > s2.my.net.3290: P 1:19(18) ack 9 win 57920 (DF) 17:07:15.098039 ant.POP3SERVER.pop3 > s2.my.net.3290: . 19:1467(1448) ack 9 win 5 7920 (DF) 17:07:15.358492 s2.my.net.3290 > ant.POP3SERVER.pop3: . ack 1467 win 56472 (DF) [tos 0x10] 17:07:15.358524 ant.POP3SERVER.pop3 > s2.my.net.3290: . 1467:2915(1448) ack 9 win 57920 (DF) 17:07:15.358536 ant.POP3SERVER.pop3 > s2.my.net.3290: . 2915:4363(1448) ack 9 win 57920 (DF) 17:07:15.358547 ant.POP3SERVER.pop3 > s2.my.net.3290: . 4363:5811(1448) ack 9 win 57920 (DF) 17:07:15.631304 s2.my.net.3290 > ant.POP3SERVER.pop3: . ack 2915 win 57920 (DF) [tos 0x10] 17:07:15.631333 ant.POP3SERVER.pop3 > s2.my.net.3290: . 5811:7259(1448) ack 9 win 57920 (DF) 17:07:15.669195 s2.my.net.3290 > ant.POP3SERVER.pop3: R 3334679000:3334679000(0) win 1 17:07:15.906823 s2.my.net.3290 > ant.POP3SERVER.pop3: . ack 7259 win 57920 (DF) [tos 0x10] byte 144417:07:15.096321 s2.my.net.3290 > ant.POP3SERVER.pop3: P 3334678991:3334679000(9) ack 1566293258 win 57920 (DF) [tos 0x10] 17:07:15.096459 ant.POP3SERVER.pop3 > s2.my.net.3290: P 1:19(18) ack 9 win 57920 (DF) 17:07:15.098039 ant.POP3SERVER.pop3 > s2.my.net.3290: . 19:1467(1448) ack 9 win 57920 (DF) 17:07:15.358492 s2.my.net.3290 > ant.POP3SERVER.pop3: . ack 1467 win 56472 (DF) [tos 0x10] 17:07:15.358524 ant.POP3SERVER.pop3 > s2.my.net.3290: . 1467:2915(1448) ack 9 win 57920 (DF) 17:07:15.358536 ant.POP3SERVER.pop3 > s2.my.net.3290: . 2915:4363(1448) ack 9 win 57920 (DF) 17:07:15.358547 ant.POP3SERVER.pop3 > s2.my.net.3290: . 4363:5811(1448) ack 9 win 57920 (DF) 17:07:15.631304 s2.my.net.3290 > ant.POP3SERVER.pop3: . ack 2915 win 57920 (DF) [tos 0x10] 17:07:15.631333 ant.POP3SERVER.pop3 > s2.my.net.3290: . 5811:7259(1448) ack 9 win 57920 (DF) 17:07:15.669195 s2.my.net.3290 > ant.POP3SERVER.pop3: R 3334679000:3334679000(0) win 1 17:07:15.906823 s2.my.net.3290 > ant.POP3SERVER.pop3: . ack 7259 win 57920 (DF) [tos 0x10] 17:07:15.906852 ant.POP3SERVER.pop3 > s2.my.net.3290: R 1566300516:1566300516(0) win 0 _________________________________________________________________ 与联机的朋友进行交流，请使用 MSN Messenger: http://messenger.msn.com/cn
