    network device that it is supposed to pick up , therefore Iam unable
    to connect to the LPAR thru telnet . Can anybody Help ?

    hello,
    i will assume you have the redhat build that is meant for the z900 - it is kinda hard for me to find specs on this machine, esp. the networking part. is there any option for adding a network interface when you run redhat-config-network (something like that...) or netconfig?

    I tried tweaking my Linux box to change some network config
    stuff but it does'nt give any results
    When I install Linux on Zseries and when it comes to configuring the network interface it says it cannot find any
    device
    Or rather when I type "ifconfig eth0" at command prompt
    it gives me a message:
    Error finding interface information
    Device not found

    Please help

    Re:Problems in installing RedhatLinux on Z900

    here try this :

    type dmesg | less (the bar there is the pipe, in case you didnt know, or wasnt clear. My pipe is near my backspace key.)

    Then scroll on down. You should see where there is a bunch of parts being identified and a driver being attatched. Keep going until you discover

    a) No NIC being seen.
    b) A NIC is found, and it happens to use XXYYZZ driver.

    This will clue us into the next step. Obviously if there is no NIC being detected, that sucks, and may want to try antoher one. Possibly another brand. I have been using the $20 linksys cards for some time now with great reliability.

    if you see a detected NIC, you can run setup from the command line as root.
