  1. Moving IP address information from bge0 to bge1: Solaris 8

    Hi,

    OS: Solaris 8
    Hardware: Sun-Fire-V210

    Initially only one of it's 4 ethernet interfaces was configured for
    the network connectivity. Recently, all types of communication ends up
    freezing (ssh, ftp) and the ping replies are intermittent. The cable
    connection and the switch ports are okay.

    Windows_machine>ping 10.1.1.2 -t

    Pinging 10.1.1.2 with 32 bytes of data:

    Reply from 10.1.1.2: bytes=32 time<1ms TTL=255
    Request timed out.

    Request timed out.
    Reply from 10.1.1.2: bytes=32 time<1ms TTL=255
    Request timed out.

    Then I wanted to change the interface settings from bge0 to bge1 after
    connecting the cable to corresponding ethernet port. I un-"plumb"ed
    bge0 before I come up with bge1.

    # cat /etc/inet/hosts
    10.1.1.1 test1.test.org test1
    10.1.1.2 test2.test.org test2

    # cat /etc/hostname.bge1
    test2.test.org

    # cat /etc/netmasks
    10.1.1.0 255.255.0.0

    # cat /etc/defaultrouter
    10.1.1.90

    I also edited the following file to update the host information as
    "test2" ...

    /etc/nodename
    /etc/net/ticlts/hosts
    /etc/net/ticots/hosts
    /etc/net/ticotsord/hosts
    /var/crash

    Just to check whether the settings are staying or not, I rebooted the
    whole system. The "ifconfig -a" doesn't return any IP address as
    configured. We can't communicate with the system unless we use this
    command:

    # ifconfig bge1 10.1.1.2 netmask 255.255.0.0 broadcast 10.1.255.255
    plumb up

    What am I missing? I might plan for IP multipathing as it started from
    Sol 8.

    did you do a reconfiguration boot?

    reboot -- -r

    Please provide "netstat -nr" and "ifconfig -a" output from the Solaris
    system and some basic information about your network. (Is the netmask
    really 255.255.0.0? Are all the machines on that network configured
    that way?)

    That's not going to work. You're telling the system to configure a
    non-existent interface, and then plumb it afterwards. That should be:

    # ifconfig bge1 plumb 10.1.1.2 netmask 255.255.0.0 \
    broadcast 10.1.255.255 up

    Or, equivalently, and more concisely:

    # ifconfig bge1 plumb 10.1.1.2/16 broadcast + up

    Thanks for the replies. After the reboot, the ifconfig -a returns

    lo0: flags=1000849 mtu 8232 index
    1
    inet 127.0.0.1 netmask ff000000
    bge1: flags=1000842 mtu 1500 index 3
    inet 10.1.1.2 netmask ff000000 broadcast 10.255.255.255
    ether x:x:xx:xx:xx:xx
    bge2: flags=1000843 mtu 1500
    index 2
    inet 192.168.100.3 netmask ffffff00 broadcast 192.168.100.255
    ether x:x:xx:xx:xx:xx

    Here I configured annex to be connected to bge2. You are right. The
    broadcast seems to be a issue here. How do I change that? What should
    be the value of /etc/netmasks for network 10.1.1.0?

    # netstat -nr

    Routing Table: IPv4
    Destination Gateway Flags Ref Use Interface
    -------------------- -------------------- ----- ----- ------ ---------
    192.168.100.0 192.168.100.3 U 1 0 bge2
    127.0.0.1 127.0.0.1 UH 3 6 lo0

    Here is a problem. It doesn't say anything about network 10.1.1.0 and
    how that should be routed. How do I fix that?


    TIA

    So, now you're using a /8 netmask on that network. What's the *right*
    netmask?

    Note that this interface isn't marked "up." What exactly do you have
    in /etc/hostname.bge1?

    It's almost certainly not going to run correctly if the netmask issue
    isn't resolved and the interface isn't enabled (marked "up").

    I can't answer that question. This is something that has to come from
    *you* or your local network administrator. Netmasks are a property of
    the local network configuration. They're not something that can be
    deduced from an IP address -- even one that's called a "network."

    Plausible masks corresponding to network 10.1.1.0 are /24 through /30,
    which correspond to these:

    255.255.255.0
    255.255.255.128
    255.255.255.192
    255.255.255.224
    255.255.255.240
    255.255.255.248
    255.255.255.252

    It's not there because bge1 has been marked "down" administratively.

    Most likely, it's due to a bad entry in /etc/hostname.bge1. Probably,
    you have multiple lines in that file rather than a single line.

    How many addresses are you using in that address space?

    Remember that the netmask is logically "anded" with an IP address to
    determine whether the address is "local" or not. There are potentially
    2^24-1 addresses in that space. If you are using 10.1.1.0 through
    10.1.1.255 then your netmask would be 255.255.255.0. Since that address
    space is designated as an RFC-1918 private network you could assign all
    2^24-1 addresses and use 255.0.0.0 as a netmask if you wish.


  7. Re: Moving IP address information from bge0 to bge1: Solaris 8

    Thanks for the reply. It worked. I had extra blank line in /etc/
    hostname.bge1 and /etc/inet/netmasks files.

    I'm employing 254 hosts in this subnet, and that should be a
    10.1.1.0/24 network with netmask 255.255.255.0. Thinking that network
    as Class A (private), I used the default netmask 255.255.0.0
    previously. Now, both works.

    You are right here. Deleting the blank lines made it work.

    # ifconfig -a
    bge2: flags=1000843 mtu 1500
    index 3
    inet 10.1.1.2 netmask ff000000 broadcast 10.255.255.255
