    Could anyone help with the following problem:

    What I try to achieve: Using tcp/ip (telnet, ping , ftp) straight from Linux.
    What I have: RH 6.2, kernel 2.2.14-5 on pentium II 300
    ax25 installed as modules, complete with mkiss etc.
    With it I run successfully the following software: Xastir (aprs), Linpac (which
    uses the ax25 utils files like listen and call)
    By sending a kill sig to kissattach I can then run TNOS v 2.3 .

    When I try a telnet direct from a linux terminal to a 44.x.x.x address I get
    the following msg.

    [root@reica /root]# telnet 44.136.138.1
    Trying 44.136.138.1...
    telnet: Unable to connect to remote host: No route to host

    Same happens with 'ping'

    The kernel routing table:

    [root@reica /root]# route
    Kernel IP routing table

    44.0.0.0 * 255.0.0.0 U 0 0 0 ax0

    the ifconfig cmd:

    [root@reica /root]# ifconfig
    ax0 Link encap:AMPR AX.25 HWaddr VK4ALJ

    the host file:

    127.0.0.1 localhost
    10.0.1.1 reica reica.booyul
    10.0.1.2 seffie seffie.booyul
    203.17.118.2 mail.ion.com.au

    44.136.141.100 vk4rza vk4rza.lan
    44.136.141.29 vk4bvy-2.ampr.org

    The packets are going out to tnc and up the spout.
    Example: telnet 44.136.138.1
    The trace (and the only trace!):

    [Mon Jan 22 12:39:47 2001]
    Port 2: AX25: VK4ALJ->QST <UI> pid=ARP
    ARP: len 30 hwtype AX25 prot 0x800 prlen 4 op REQUEST
    sender hwaddr VK4ALJ
    target

    note: no target address. The same trace for a ping to any address.

    Where do I go wrong????? Address Resolution Protocol not doing its job??
    Any pointers in the right direction will be gratefully received.
