[nos-bbs] ip-ip

[N0MR]

Thanks Bob,

First, how do I shut off the tcpdump or does it not hurt to just leave it 
run?

I see the following:

This came in when the encap RIP broadcast was sent.

04:33:25.795686 IP amprgw.sysnet.ucsd.edu > 192.168.0.76: IP
gw.ampr.org.route > RIP2-ROUTERS.MCAST.NET.route: RIPv2, Response,
length: 164 (ipip-proto-4)

This is an AXIP broadcast.

04:30:38.889266 IP vci-113.dsl.onvoy.net > 192.168.0.76: IP
kunk.n0qbj.ampr.org > n0mr.ampr.org:  ax.25 172 (ipip-proto-4)

I did a telnet and this came in.

04:29:51.638836 IP 69.196.157.57 > 192.168.0.76: IP
port.ve3mch.ampr.org.telnet > n0mr.ampr.org.4249: F 1659:1659(0) ack 48
win 2048 (ipip-proto-4)
04:29:51.639707 IP 192.168.0.76 > 69.196.157.57: IP n0mr.ampr.org.4249 >
port.ve3mch.ampr.org.telnet: F 48:48(0) ack 1660 win 2048 (ipip-proto-4)

>From the above information, it appears to me that my ip-ip tunnel acitivity 
is working with DMZ open to JNOS. Comments?
