guest to guest - pingable but no route to host

[dvb]

Hi,

Perhaps this has already been dealt with, apologies in advance:

Using Parallels Desktop of Mac, I have two linux guest hosts running (FC6 and rpath), each is connecting to the internet without problems via Shared Networking respectively as 10.211.55.4 and 10.211.55.5. My OSX machine's en3 interface is 10.211.55.2.

All hosts are pingable and tracerouteable from each of the others.

However accessing the SugarCRM website on .5 is a problem. At no point have I been able to connect to http://10.211.55.5 from .4 or .2. As well, I thought that I should be able to ssh into .4 from .5 but ssh just hangs in space.

Only when I tried to connect via "wget http://10.211.55.5" from .4 then I got a "no route to host" error message.

Any help would be greatly appreciated. Firewalls are open on .4 and .5 for ports 80.

Thanks.

oh! I got it...my bad!

Cleared my head and started from scratch.

I found that the firewall on .5 was not open as I had previously thought.

To open it I did:

/etc/rc.d/init.d/iptables stop

which let port 80 through immediately; ssh soon followed when I tweaked:

/etc/ssh.d/sshd_config

~

The best option of course is to fine tune /etc/sysconfig/iptables and then:

/etc/rc.d/init.d/iptables restart

I'm glad this is working because now I have a new dev server!

Glad I can help

Also... for others... you might need to check router settings... some hardware routers do not allow communication locally but it can be turned on - Internet Access will be on, Local Access is Off etc.
