Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi all, I am having a rather strange problem with my network interface in FreeBSD 4.2/4.3. It is an sis900 card which appears to be fully supported and was detected on install. Nothing further has been done to the machine (it is a brand new *vanilla* install of 4.3). The problem almost appears to be the machine being sleepy and failing to reply to network requests until it is rudely awakened. After the machine has been idle for an hour or so (no logins and little activity) the ethernet card fails to respond when a connection is attempted via ssh/ftp/telnet/etc... To 'wake-up' the interface, I must ping the machine from within the subnet and I seem to loose the first packet? (NB: if I ping the machine from outside the subnet I loose all packets) (from within the subnet) PING tulip... (xxx.1.242.xxx): 56 data bytes 64 bytes from xxx.1.242.xxx: icmp_seq=1 ttl=255 time=0.6 ms 64 bytes from xxx.1.242.xxx: icmp_seq=2 ttl=255 time=0.5 ms 64 bytes from xxx.1.242.xxx: icmp_seq=3 ttl=255 time=0.5 ms Note that icmp_seq=0 is lost. Once, the machine 'wakes up' the card appears fine and I can connect to it from outside the subnet. ifconfig gives the following: sis0: flags=8843 mtu 1500 inet xxx.1.242.xxx netmask 0xfffff800 broadcast xxx.1.247.xxx inet6 fe80::240:33ff:feab:fd85%sis0 prefixlen 64 scopeid 0x1 ether 00:40:33:ab:fd:85 media: autoselect (100baseTX ) status: active supported media: autoselect 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP none I am in the process of turning on excessive levels of debugging and I'll post more when I get it. In the meantime, does anyone have any ideas as to what is going on here? Any hints of what I should be looking at?
