I connected 2 comps(anos and anos2 both on AUROX linux(10.0 and 9,3)) straight to interfacies eth0 (192.168.0.1) <--> eth0(192.168.0.2) by crossed cable rj-45.
Route table is set well. Pinging anos2 from anos and anos from anos2 says evertything is ok.
But when I'm tring to use some service (telnet) etc. it says "no route to host" ???
And comp which is server sends ICMP msg: "icmp 68: host anos unreachable - admin prohibited"
I don't usualy talk to myself...but the solution is simply:
I had firewall enebled without any allows
It is fxed.
Old thread but when I did a google search this is the thread that showed up which was similar to my problem ....and just like you, the firewall was the issue. All fixed and good to go.
Thanks for answering your own question keraj37. It helped me out today.

Old Thread but still useful to someone about every 4 years it seems as I just ran into this problem today and indeed it was the firewall! Thanks again for answering your own question 8 years ago!

I had the same issue - During TCP handshake the client would send a 'Destination Unreachable - Communication with Destination Host is Administratively Prohibited' (ICMP Type 3 Code 10) message. The handshake would complete but because of the ICMP message, server would send a reset (RST) without the actual application-level (HTTP, in my case) transaction taking place.
I had to add the following rule on the client to drop such ICMP packets:
Code:
iptables -A OUTPUT -p icmp -s <client IP> --icmp-type 3/10 -j DROP
From then on, the client and server were able to transact over application layer without any issues.
