Tinc1.0pre4 & kernel 2.4.5 & tun/tap - Correction

[Igor Belokopytov]

 Hello Guus,

I fogot to tell that if I try "ifconfig test4 hw ether fe:fd:00:00:00:00" I get
ping reply with errors, if I don't I get no reply.

--------------------------------------------------------------------------------------------

 I had such file (usr/include/linux/if_tun.h), but it was not symlink to
/usr/src/linux/include/linux/if_tun.h  (file in  directory usr/include/linux was
newer). I made such symlink and recompiled tincd. Now I have  message "/dev/tun is

a new style tun/tap device" in syslog file, I can create <netname> interface and
can create connection with other peer.
But this connection is so bad (ping results in attached file "ping") Other peer
use kernel 2.2.17, tincd 1.0pre4 with ethertap interface (tap0)
Also I got error message from other peer (with kernel 2.2.17 and tap device) I
attached it as file "log"

This is my config files
Host "Test"

/etc/tinc/test4/tinc.conf:
Name = test
PrivateKeyFile = /etc/tinc/test4/rsa_key.priv
TapDevice = /dev/tap0

tinc-up:
#!/bin/sh
insmod ethertap -o "ethertap0" unit=0
ifconfig tap0 hw ether fe:fd:00:00:00:00
ifconfig tap0 10.168.99.221 netmask 255.255.0.0
ifconfig tap0 -arp
/sbin/tincd4 --net=test4 -ddddd

Host "Igor"

/usr/local/etc/tinc/test4/tinc.config:
Name = igor
ConnectTo = test
TapDevice = /dev/tun
PrivateKeyFile = /usr/local/etc/tinc/test4/rsa_key.priv

tinc-up:
#!/bin/sh
tincd -n test4
ifconfig test4 hw ether fe:fd:00:00:00:00   # without this command I get nothing
ifconfig test4 10.168.89.2 netmask 255.255.0.0 -arp

Hosts files are the same for both hosts
