I have a proxy server (with Squid3) setup in an old machine.
Recently, while downloading, I lose the connection. At that time, I can't even SSH into the proxy. When I press a key in the keyboard (of the proxy server) the connection comes back! I tried with Ubuntu 11.10 and Debian 6 - both have the same issue!
I also checked the "ifconfig" result... It showed 1269 dropped packets :
eth0 Link encap:Ethernet HWaddr 00:0c:76:c2:de:ef inet addr:10.0.0.100 Bcast:10.0.0.255 Mask:255.255.255.0 inet6 addr: fe80::20c:76ff:fec2:deef/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:964533 errors:0 dropped:1269 overruns:0 frame:0 TX packets:1183810 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:925950757 (883.0 MiB) TX bytes:926726143 (883.7 MiB) Interrupt:23 Base address:0xe400
I checked again after another connection drop and the dropped count increased to 1701. When I issue "ip -s link show eth0", it gave me this :
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:76:c2:de:ef brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 941833855 980298 0 0 0 0 TX: bytes packets errors dropped carrier collsns 942639027 1201568 0 0 0 0
I like to know whether it's a hardware problem or a software problem... If it's the software, how can I fix this?
PS : I just changed the network card and still the problem is there!
