Thread: Can't ping hosts across wireless network

    Can't ping hosts across wireless network

    Hi All,

    hopefully somebody can tell me what I'm doing wrong here, or point me to a way in which I can diagnose the problem.

    I have a home wireless network using a Belkin Wireless G router. I have disabled the firewall on the router for now, to eliminate that from the list of possible causes. My ultimate aim is to get a samba server running, and I have that server operating OK to the point that I get a decent response to the command below:

    smbclient -L DESKTOP1
    Enter jeff's password:
    Domain=[LIMEYNET] OS=[Unix] Server=[Samba 3.4.2-1.1.3.1-2229-SUSE-SL11.2]

    Sharename Type Comment

    Server Comment
    --------- -------
    DESKTOP1 Samba 3.4.2-1.1.3.1-2229-SUSE-SL11.2

    Workgroup Master
    --------- -------
    LIMEYNET DESKTOP1

    I can see the LIMEYNET workgroup at my Windows PC, but can not get a response when I try to ping the DESKTOP1 server from another machine, or try to descend into the LIMEYNET workgroup on the windows laptop using windows explorer. Pinging desktop1 locally does provide a good response via 127.0.0.2

    Reviewing the wireless router, which is running DHCP. the DESKTOP1 server has been assigned the connections 192.168.2.2 and 192.168.2.3 (two separate IDs - I believe it is seeing the other unused ethernet card in my desktop through the loopback interface - see ifconfig -a response below.

    When I try to ping the DESKTOP1 network, however, the remote machine attempts to ping 207.69.131.9. This is not an address which makes sense to me, as it is not one of my internet provider nameserver addresses from /etc/resolv.conf

    ### /etc/resolv.conf file autogenerated by netconfig!
    #
    # Before you change this file manually, consider to define the
    # static DNS configuration using the following variables in the
    # /etc/sysconfig/network/config file:
    # NETCONFIG_DNS_STATIC_SEARCHLIST
    # NETCONFIG_DNS_STATIC_SERVERS
    # NETCONFIG_DNS_FORWARDER
    # or disable DNS configuration updates via netconfig by setting:
    # NETCONFIG_DNS_POLICY=''
    #
    # See also the netconfig(8) manual page and other documentation.
    #
    # Note: Manual change of this file disables netconfig too, but
    # may get lost when this file contains comments or empty lines
    # only, the netconfig settings are same with settings in this
    # file and in case of a "netconfig update -f" call.

    ### Please remove (at least) this line when you modify the file!

    For your windows PCs you will have to enable "Client for Windows Netwoeks" (Vista) in the NIC card properties to get the browsing working. I think in XP its NetBIOS or something like it.

    What do you mean by the desktop1 network? The desktop server's IP address or the base network address for the entire network? You may have DNS configured incorrectly too, which is why you are getting referred to the Internet when you are trying to ping a local machine.

    Thanks - I'll take a look at the PC tomorrow to check the configuration, though since this is my work machine, and connects regularly to the company network, I'm expecting to find that will be already set up.

    I used the command 'ping desktop1' from both my windoze and linux laptops, and in both cases, the computer reported that it was attempting to ping 207.69.131.9 - you may be right about DNS configuration - can you point me to any handy references that would explain how to set up DNS correctly, or advise any diagnostic steps to take?

    Though my ultimate aim is to have a network drive that is accessible from windoze, I'd initially be happy to be able to access a drive on my SUSE desktop from my SUSE laptop (I just erased the gentoo OS from my linux laptop and installed SUSE).

    Jeff
