> Can you reproduce it with other ftp client and/or server? O.K. I wiil try to test other ftp client and server.
> Please provide the output of "netstat -na" command during the > transfer, and the output of "lsmod | grep conntrack" (just for > sure). Please see the output of "netstat -na" when stuck. (below) CONFIG_NETFILER is diabled in my test configuration ,conntrack modules is not loaded. (CONFIG_IP_DCCP, CONFIG_IP_SCTP, CONFIG_TIPC, CONFIG_IPV6 is also disabled) > What kind of mode do you use? e.g. PORT/EPRT/LPRT/PASV/EPSV/LPSV PASV mode. > When the transfer get stuck, are other communication still working? Other communication works properly. Actually, I can start other ftp session on other console of the same PC. > Are there any workaround? > e.g. stop-start vsftpd cycle, ifdown-ifup cycle, rmmod/insmod cycle etc. I only need to do the killall command. >> output of netstat -na Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN tcp 0 0 192.168.0.6:35737 192.168.0.2:26827 TIME_WAIT tcp 0 0 192.168.0.6:51036 192.168.0.2:21 ESTABLISHED udp 0 0 0.0.0.0:68 0.0.0.0:* udp 0 0 0.0.0.0:867 0.0.0.0:* udp 0 0 0.0.0.0:870 0.0.0.0:* udp 0 0 0.0.0.0:111 0.0.0.0:* Active UNIX domain sockets (servers and established) Proto RefCnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 5056 /tmp/.font-unix/fs7100 unix 2 [ ] DGRAM 1234 @/org/kernel/udev/udevd unix 5 [ ] DGRAM 4748 /dev/log unix 2 [ ACC ] STREAM LISTENING 4917 /var/run/dbus/system_bus_socket unix 2 [ ACC ] STREAM LISTENING 4989 /var/run/acpid.socket unix 2 [ ] DGRAM 5390 unix 3 [ ] STREAM CONNECTED 4920 unix 3 [ ] STREAM CONNECTED 4919 unix 2 [ ] DGRAM 4866 unix 2 [ ] DGRAM 4756 Thanks, Best Regards Komuro - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
