can't ping (tcp/ip)

[michael.renner@gmx.de]

Hello,
two years ago, a I had my first experience with ax25
(amateur radio and cb)
Now I planed to configure ax25 again, to connect
my linux box with the linux box from a friend, not
far from here.
Setup here:
slink with 2.0.36 (self compiles, ax25 support
as modules)
tnc2S with two 1k2 modems (one for ham radio,
the other one for cb)
        /sbin/modprobe mkiss
        /usr/sbin/mkiss -s 9600 /dev/ttyS1 /dev/ptypa /dev/ptypb 
        /usr/sbin/kissattach /dev/ttypa port0
        /sbin/ifconfig ax0 44.130.176.68 netmask 255.255.255.0 up
        /sbin/ifconfig ax0 broadcast 44.130.176.255 mtu 512 
        /usr/sbin/kissattach -i 192.168.127.2 -m 1024 /dev/ttypb port1
        /sbin/route add -net 44.0.0.0 netmask 255.0.0.0 ax0
        /sbin/route add -net 192.168.127.0 ax1 
        kissparms -p port0 -t 300 -s 100 -r 25
        kissparms -p port1 -t 200 -s 100 -r 25  

After all, ifconfig says:
ax0       Link encap:AMPR AX.25  HWaddr DD0UL-1
          inet addr:44.130.176.68  Bcast:44.130.176.255  Mask:255.255.255.0
          UP BROADCAST RUNNING  MTU:512  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
          Collisions:0


ax1       Link encap:AMPR AX.25  HWaddr LINUX2
          inet addr:192.168.127.2  Mask:255.255.255.0
          UP RUNNING  MTU:1024  Metric:1
          RX packets:1 errors:0 dropped:0 overruns:0 frame:0
          TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
          Collisions:0  

And route:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
localnet        *               255.255.255.0   U     0      0        3 eth0
192.168.127.0   *               255.255.255.0   U     0      0        2 ax1
127.0.0.0       *               255.0.0.0       U     0      0        4 lo

But I can only ping to my own IP adress without error messages:
cassiopeia:/etc/init.d # ping -c 1 44.130.176.68
PING 44.130.176.68 (44.130.176.68): 56 data bytes
64 bytes from 44.130.176.68: icmp_seq=0 ttl=64 time=0.6 ms

When I try to ping an other IP adress on the same network an error:
cassiopeia:/etc/init.d # ping -c 1 44.130.176.69
PING 44.130.176.69 (44.130.176.69): 56 data bytes
ping: sendto: Operation not permitted
ping: wrote 44.130.176.69 64 chars, ret=-1   

What is wrong? Which command do i have to add to my script?

Thanks for your help!
Michael, DD0UL
