    Hi all,

    I am using packet radio only in a room
    |pc1|--|sc1|--|ht1| <~~~~> |ht2|--|sc2|--|pc2|

    The hardware and software are: Personal Computer,
    Sound Card, HT, RH Linux 7.1 kernel upgraded 2.4.19
    and packet radio stuff (libax25-0.0.10,
    ax25-apps-0.0.6, ax25-tools-0.0.8, node.0.3.0,
    soundmodem-0.7)

    First of all I am using stereo cable to connect 2
    machines without ht and checking if the TCP/IP
    facilities works such as ping, ftp, telnet and ssh.
    |pc1|--|sc1|--------|sc2|--|pc2|}
     
    [my1com]# ifconfig
    ..
    sm0 Link encap: AMPR AX.25 HWaddr MY1COM inet addr:
    44.128.1.20 Bcast: 44.128.1.255 Mask: 255.255.255.0
    ..
    [my1com]# route add 44.128 1.21 sm0
    [my1com]# arp -n 44.128.1.21 -H ax25 -s MY2COM -i sm0
    [my1com]# cat /proc/net/arp

    [my1com]# cat /etc/ax25/axports
    ..
    radio MY1COM 1200 255 2 sound card
    [my2com]# ifconfig }
    ..
    sm0 Link encap: AMPR AX.25 HWaddr MY2COM inet addr:
    44.128.1.21 Bcast: 44.128.1.255 Mask: 255.255.255.0
    ..
    [my2com]# route add 44.128.1.20 sm0
    [my2com]# arp -n 44.128.1.20 -H ax25 -s MY1COM -i sm0
    [my2com]# cat /proc/net/arp

    Device
    44.128.1.20 0x3 0x6 MY1COM-0 * sm0
    [my2com]# cat /etc/ax25/axports
    ..
    radio MY2COM 1200 255 2 sound card

    The connection using stereo cables as follow:
    MIC-sc1|----|SPK-sc2
    SPK-sc1|----|MIC-sc2
     
    With help from Wilbert Knol (ZL2BSJ) and other
    members: the "ping", "ftp", "ssh" and "telnet"
    commands work from pc1 to pc2 and virce virca :-)
    Thanks a lot people!

    Now, I am trying using HT, but all commands (ping,ftp,
    ssh, telnet) don't work ;-(
    |pc1|--|sc1|--|ht1| <~~~~~> |ht2|--|sc2|--|pc2|

    [my1com]$ ping -i 3 my2com
    PING my2com.ampr.org (44.128.1.21) from 44.128.1.20:
    56(84) bytes of data.

    --- my2com.ampr.org ping statistics ---
    4 packets transmitted, 0 packet received, 100% packet
    loss
    [my1com]$

    Please any idea and help what should I do to make
    ping, ftp, ssh and telnet commands workable and
    useable?

    Thanks in advance
    Vivi
