| I have a linux slackware server with 3Com NIC (Connected to ISP)and Realtek NIC connected to the Home LAN. I can change the NIC settings on the windows workstations to support 100mbps full duplex but when it detects that my server NIC is running at 10Mbps I cant stablish a connection..
The Q is how do you change the NIC settings to run at 100 instead of 10? Is there a parameter u can add when loading the NIC driver module? | |

Assuming the driver you're using can handle 100mbps you can set this through the ifconfig "media" parameter. Running ifconfig only makes temporary changes though; the next time you reboot your NIC would revert back to 10mbps. I'm not sure what file you need to edit to make this change permanent in Linux. | |

| i am thinking about 2 or 3 approaches
one is what cci2be suggested
# ifconfig eth1 media 100baseT
port: SIOCSIFMAP: Operation not supported
maybe the type isnt correct? the manpage has no detailed info on this
the second one is eliminated which is passing the parameters when loading the module, because i didnt compile it as a module but compiled it into the kernel.
third and last option i have is pass the ether= parameter at the LILO prompt.
0x04 should be fukk duplex?
or whats the exact parameters that could change the settings of those 2 cards i have to 100Mbps full?

| Yeah, I noticed the ifconfig man page was lacking on details. I guess the best thing to do would be to search for a more detailed doc.
This may be what you need to make a more permanent change. | |
