ICMP host unreacable

ICMP host unreacable

Post by david tiber » Mon, 10 Sep 2001 04:53:07



I am setting up my first solaris machine. i can reach my internal
network but nothing external.

I do not know what "BASE-ADDRESS.MCAST.NET" is, but its IP address is
224.0.0.0. My netmask is 255.255.255.224, so I figure this is the
problem.
I saw 224.0.0.0 somewhere when setting up and thought it looked wrong.

I have 209.166.53.32 to 209.166.53.63. my router is 209.166.53.33

any help in how to configure this? I just installed it today.

# ping 209.166.53.33
209.166.53.33 is alive

# ping yahoo.com
ICMP Host Unreachable from gateway spider (209.166.53.34)
 for icmp from spider (209.166.53.34) to img3.yahoo.com
(216.115.108.243)

# netstat -r

localhost            localhost             UH       2     14  lo0

this is my routing table on a linux machine:

224.0.0.0: multicast, a reserved ip similar to 127.0.0.1

Add your router's ip to /etc/defaultrouter

You don't have a default route and the file for that, appropriately
enough, is /etc/defaultrouter.  Execute this:

# route add default 209.166.53.33
# echo "209.166.53.33" > /etc/defaultrouter

 
 
 

1. ICMP HOST cannot build IP Header address to echo ICMP HOST

 this is the error message i get when trying to telnet anywhere but to my
domain serveror ping anything but my domain server i also get it when logged
into any other machine but my domain server even machines on the same net will
recognize dns make an attempt then puke! i assume this a problem in my
config which is preventing the returning or "echoing" of the returns off of
commands that require two way communication i have tried everything that i
know and then some!! please HELP ME !!!!!!!!!!!!
