Hey Y'all,
I just set up a new old machine on my network. I did a net install of
CentOS 6.7 on it replacing an outdated copy of Win XP. Of course I'm
now in the throws of configuring the machine to be a useful member of
society.
[mlapier at peach ~]$ nmap -sn 192.168.15.0/24
Starting Nmap 5.51 ( http://nmap.org ) at 2015-08-23 20:12 EDT

I can ssh onto 192.168.15.107 too.
I spent a good part of the day trying to connect the FAHControl on my
machine to the Folding at Home client on 192.168.15.107 without success.
Maybe the reason why 192.168.15.107 does not appear on the nmap output
has something to do with my lack of success connecting the control to
the client. Maybe not.
I'm not having any problem connecting to the FAH client on
192.168.15.105 from my machine. I even copied the FAH configuration
file from 192.168.15.105 to 192.168.15.107 and then restarted the
client. Still no joy in Mudville. I figure I should quit while I'm
behind. Anyone have any suggestions?

Now I'm feeling like and idiot. "I'm sure you turned off firewall:" NOT. I guess tomorrow I've got some iptables rules to write. For now turning off iptables fixed the issue. I can connect to the FAH client and the machine appears in the nmap report. I just checked 192.168.15.105 and found that iptables is turned off there too. Thank you so much for the brain reset. -- _ ?v? /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****
