Hi folks, I have a kind of serious problem with my D-Link DFE530-TX NIC. Let me give you some details about my network and what the problem is, so that someone will probably be able to suggest something I could do to solve it: So, my LAN consists presently of 4 machines, all of which are connected by means of twisted pair Ethernet cable. I am using two hubs, which have been daisy-chained together. The network operates at 10 Mbps (10Base-T), as you will already have guessed. Three of the four machines are equipped with 10Base-T NICS, the hubs are also 10Base-T. The DFE530-TX that makes the problems is actually a 100Base-T NIC, but under the conditions outlined above, it of course also runs at 10 Mbps only. As such, it even seems to be configured fine: vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.0.5 netmask 0xffffff00 broadcast 192.168.0.255 inet6 fe80::205:5dff:fe08:caa2%vr0 prefixlen 64 scopeid 0x1 ether 00:05:5d:08:ca:a2 media: Ethernet autoselect (10baseT/UTP) status: active faith0: flags=8000<MULTICAST> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 inet 127.0.0.1 netmask 0xff000000 Now, here comes the problem: I recently tried to copy a large file (500 MB) from one machine to the DFE530 machine via FTP. Strangely, I never managed to get much more than 10% of the filed copied - after that my machine would no longer be able to communicate with the network in any way. FTP would hang, and ping wouldn't work (execpt for saying something like: "sendto: No more buffer space available"). As far as my solution to this problem is concerned, well, I can do "ifconfig vr0 down" followed by "ifconfig vr0 up" and the card will respond again. However, it will hang again quiet soon (for example, when I try to retransmit my 500 MB file). It should ne noted that every now and then (but without a clear pattern) I also received a message saying "vr0: watchdog timeout". So, what do I do? Any suggestions? I thought that I should probably try changing the current setting of my card from "media autodetect" to fixed "10baseT/UTP", but I'm not sure if that will help, since the above ifconfig output suggests that the network medium has been recognized successfully. Any suggestions are welcome - oh, and for information purposes, I added below the section of my /var/log/messages where the network card is being detected/initialized.
