Re: [BUG KERNEL 2.6.20-rc1] ftp: get or put stops during file-transfer
Can you reproduce it with other ftp client and/or server? I tried the proftpd-1.3.0a-1.fc6(kernel version is 2.6.19). The ftp stop problem does not happen. Therefore, this problem is reproduced when client's kernel-version is 2.6.20-rc1 or later and server is vsftpd. Server's kernel-version is not related with this problem. The ftp-stop-problem happens on client's PC. Please advise.

Re: [BUG KERNEL 2.6.20-rc1] ftp: get or put stops during file-transfer
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 tcp0 0 0.0.0.0:873 0.0.0.0:* LISTEN tcp0 0 0.0.0.0:111 0.0.0.0:* LISTEN tcp0 0 192.168.0.6:35737 192.168.0.2:26827 TIME_WAIT tcp0 0 192.168.0.6:51036 192.168.0.2:21 ESTABLISHED udp0 0 0.0.0.0:68 0.0.0.0:* udp0 0 0.0.0.0:867 0.0.0.0:* udp0 0 0.0.0.0:870 0.0.0.0:* udp0 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 [ ] DGRAM1234 @/org/kernel/udev/udevd unix 5 [ ] DGRAM4748 /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 [ ] DGRAM5390 unix 3 [ ] STREAM CONNECTED 4920 unix 3 [ ] STREAM CONNECTED 4919 unix 2 [ ] DGRAM4866 unix 2 [ ] DGRAM4756 Thanks, Best Regards Komuro - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
