ssh is working perfectly fine between fc6 and fc5 installations I have at work.
the ubuntu box i believe is the issue.
dont know yet what the issue is.
this was working fine on an earlier version of ubuntu. I was running ubuntu 5.1 earlier and did not have this problem.
only on 7.1
will moving to 8.04 solve this issue.
Chocolate-Covered Ubuntu Beans
The details for ssh authentication are in /var/log/secure, and it does not even show any ssh connection attempts from 192.168.1.70 for today. That is the ip address of the Ubuntu machine, correct?Originally Posted by vidyadhara
If you feel comfortable with it, I would like to see the results of these commands on the Fedora and the Ubuntu side:
Code:iptables -n -L iptables -t nat -n -L

yes the ubuntu box is 192.168.1.70
I shut down the fedora 5 box.
I was able to connect the fedora6 box to to the fedora 5 box and vice versa.
now I am able to connect the fedora 6 box to ubuntu box and vice versa at double speed with no hitches.
there is a genie in the bottle.
the tcpdump showed a pile of activity between the fc5 and ubuntu boxes.
how come the authentication information does not show.
Maybe i will upgrade the fc5 box shortly.
however I am having other samba connection problems with the ubuntu box.
through nautilus i.e.
makes the box somewhat difficult to use.
cant connect it to the network with any effect.
bit of a fix
started a little bit of actual work on it.

Thanks for all the help.

even ssh connection on nautilus is working from my ubuntu box to my fc6 box.
samba is not working though through nautilus.
smbclient seems to work i have to check it in the morning.

Does this do any good.

modifications to my observations.
I was actually running ubuntu 7.04.
I observed identical results from two different ubuntu 7.04 machines.
They are able to connect perfectly to my fc6 machine. the fc5 machine is able to ssh to both the ubuntu 7.04 machines. only the ubuntu 7.04 machines are not able to connect to the fc5 over ssh.
now that is a mystery.

I Installed ubuntu 8.04 on another machine. I have still the same problem / behavior between ubuntu and fc5.
fc5 is able to ssh into the ubuntu system. the ubuntu system is not able to do the reverse. There are no firewall issues because other systems are able to log into the fc5 system.
