Hi all,
I have noticed a problem with 2.1.90 and pre-2.1.91-1 (from kernel.org): while trying to establish TCP connections to remote hosts, when the network distance is very long, processes tend to hang:
0 6 10908 10905 0 0 856 388 inet_stream S ? 0:00 testhost news.povray.org -s
A netstat shows that the corresponding socket is in SYN_SENT state. I have a permanent connection to the network through a 10 Mbit/s Ethernet. Here is an excerpt of my .config:
CONFIG_NET=y # # Networking options # CONFIG_PACKET=m CONFIG_FIREWALL=y CONFIG_NET_ALIAS=y CONFIG_UNIX=y CONFIG_INET=y CONFIG_IP_FIREWALL=y CONFIG_NET_IPIP=m CONFIG_NET_IPGRE=m CONFIG_IP_ALIAS=y CONFIG_IP_NOSR=y CONFIG_SKB_LARGE=y CONFIG_IPV6=m # # Network device support # CONFIG_NETDEVICES=y CONFIG_DUMMY=m CONFIG_NET_ETHERNET=y CONFIG_NET_VENDOR_3COM=y CONFIG_VORTEX=m CONFIG_PPP=m
I also get an unrealistic number of errors on eth0 (a 3c590):
eth0 Link encap:Ethernet HWaddr 00:A0:24:16:E1:1C inet addr:137.194.8.8 Bcast:137.194.9.255 Mask:255.255.254.0 UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:277440 errors:5222820 dropped:5222820 overruns:0 frame:5225554 TX packets:70792 errors:0 dropped:0 overruns:0 carrier:135 collisions:933 Interrupt:12 Base address:0xd800
(This is with 980303 ifconfig -- thanks for all replies to my preivous post!)
If you need further information please fell free to ask.
