    Hi, ive been trying to connect my powerbook g4 to my school's lan... it just wont connect. Ive already talked to the computer tech (but he doesnt know macs) and we have not figured it out. I put in the ip address, the subnet mask, and the router address, and it still says that they dont match. Am i missing something? Im trying to connect via the internal ethernet, and ive tried 2 different cables. Is there some hidden settings or something im missing? Ive run the network wizard, and still no internet. please help.

    Firewalls? Schools tend to get firewalls that only allow certain things, rather than blocking them.

    First of all, dont bump your thread. :)
    Secondly, i have never had a similar problem so i am of virtually no use.:p
    My advice? Find a fellow student or faculty member that has a mac. From what you said, it seems to be either an issue with the information you were given or an problem with internet configurations on your PB.
    Did you talk to the head tech person there? If not, talk directly to them. From what you previously posted, it seems that you have followed the correct steps, so it may be a network issue with Macs. :(

    Sorry i couldnt be of more assistance, but good luck.

    Sounds like you are entering an invalid netmask/ip combo. Anyway, make sure to
    set the DNS server IP address as well. I don't know how familiar are you with
    the Terminal but you can use ifconfig to set just about everything related
    to your ethernet adaptor (BTW en0 is the name of ethernet interface).

    Can you explain further... im a newbie with a mac, and dont know what you are talking about. Is the "terminal" a program? where do i use/type ifconfig? what is en0 and what is an ethernet interface?

    Sounds like your school might use an http proxy. You will have to ask the school's network admin about this. In order to get it to connect, you will have to go to system preferences> network > built in ethernet > configure > proxies > and then put in the information there.

    I know that my old high school currently uses an http proxy. Why? I don't know...

    In your dock, you will find an icon which looks like a screen (see pic below),
    this is called a Terminal and it is used to excute UNIX commands.

    The command ifconfig is used to configure network interfaces (that is,
    network cards that interface with the network. This can be a WiFi card, an
    ethernet card....etc.).

    No offence, but explaining how to use the Terminal and ifconfig can go well
    beyond a couple of posts and quite frankly I don't have the time for that.
    May be other fellow Macrumors can help here. BTW, if you type in the terminal
    man ifconfig you will get information about how to use ifconfig.

    Good luck.

    I don't think his problem has anything to do with the proxy setting. If you
    read his post you will see that his problem is not being able to enter the
    IP/Netmask in the first place, he keeps getting this "Don't match" error

    The reason why anyone would use an http proxy is to both reduce uplink
    traffic and security. The http proxy caches every webpage you visit so that
    if you or someone else visit it again, it will be retrieved directly from the
    proxy's cache instead of from the internet.
