Hello, SuSE users, I have a question for you: - How can I tell whether a NIC (eth0) on a computer is actually configured to operate at 10Mbps or at 100Mbps ??? The card is declared by vendor as autosense 10/100Mbps and self-configurable, (exactly as the switch port to which it is attached), and it works - but I would like to know how can one be exact about the actual speed in any case. Is there a command or a program in Linux that can tell me this? TIA Radule Soskic

mii-tool Quite useful for determining link status, when you're too lazy to look around the back of a server. - -- James Oakley Engineering - SolutionInc Ltd. joakley@solutioninc.com http://www.solutioninc.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE89haS+FOexA3koIgRAmfeAKCMMltcDe7ncSlfMEMb2SLKjCtkEgCgqMxl 9OE9sOxNeaZ9RCBRAB0Loqk= =O+0g -----END PGP SIGNATURE-----
A sticky subject. I use a benchmark program to measure it. The first NIC I had for my laptop was a Linksys 10/100 NIC that benchmarked at roughly 10Mbps. After a bit of research I determined that the 16 bit PCMCIA cards will not achieve 100 Mbps, so I returned it and bought a Netgear cardbus (32 bit card). The Netgear card benchmarked at about 88Mbps. (Nothing against Linksys, but the store did not have any 32 bit cards in stock). Note that the lights on some dongle cords, NIC cards, switches and hubs will indicate that the card is operating at 100Mbps, but not the actual throughput that the card can sustain. The bottom line: If you have a 16 bit card (normally PCMCIA) you will not get 100Mbps. On 30 May 2002 at 12:28, Radule Soskic wrote:

Thank you guys, Program mii-tools (recommended by James Oakley - thanx again James :) works for me. It is exactly what I needed, because the machine is remote one... Best regards, Radule Soskic On Thu, 2002-05-30 at 15:06, Jerry Feldman wrote:
