When I typed ifconfig I found out I was 10baseT/UTP and half-duplex. No wonder I was getting crap speed when people uploaded and download at the same time. I have a 24/7 Carracho server in the background doing heavy traffic 24/7. However when I typed



"sudo ifconfig en0 media 100baseTX mediaopt full-duplex"



all I got was this:



" SIOCSIFMEDIA: Input/Output error"



Now, I have an inkling of an idea why. I used LANSurveyor a while ago to look at U. RI. The routers are called m205, m206, etc.



So when I typed the sudo line to change my speed and duplex it asked for a password, like this:



"[m206~] password: "



without looking carefully the first time I typed my own password, oops. Anyway, I guess the reason that I couldn't change was because I didn't know the routers password, right? Is there a way around this? Also how could I enable port forwarding so I can get P2P software to work? URI is so restrictive.

    Unless you have an OC3 or T3 connection, your half-duplex 10mb connection will be more than adequate for the internet.

    You need a password to access the router to enable port-forwarding to your specific IP address.

    OS X auto-detects what speed and duplex to use; don't bother changing it.



    The line "[m206~] password: " means your computer is named m206, and it was asking for your password.

    ah yes that's another thing. What IS my root password? Apparently my "Admin" password isn't good enough? Which is kind of retarded, since you'd think an "Admin" would be allowed, to, well, Administer.



    OK I'll leave it with autodetect, thanks for the input ya'll. Full duplex would help me if it was possible, tho, I have lots of traffic both ways.

    To set your root password you can open NetInfo Manager in the Applications/Utilities folder and go to /Users/your sys admin, and highlight and copy the encoded password in the passwrd field. No go to Users/root and paste it in the passwrd field there. I will probably ger told that that is a round-about way of doing it and it is probably "dangerous" but it works.

    Thanks I'm doing that now. So now I'll be able to sudo things. Why does this feel so roundabout?

    you don't need to be root to sudo things...

    Jeez yeah, all UNIX stuff is pointlessly obtuse.

    No, but if you haven't enabled a root user and set the root password explicitly, you can't sudo anything.
