I have edit the /etc/hosts being like this :
188.8.131.52 stuckz.cjb.net localhost
127.0.0.1 localhost.localdomain localhost stuckz.cjb.net
First off this is not your issue. but this is also not how to set up a host file.
what you just listed here is that you are attempting to telnet back to yourself.....
184.108.40.206 = you
I recommend you change the host file to be a bit more "normal"
# IP FQDN CNAME CNAME ....
127.0.0.1 localhost.localdomain localhost
220.127.116.11 stuckz.cjb.net stuckz
Now as stated. The host file should have nothing to do with your issue as your not trying to "telnet hostname" but are using the direct IP. Linux will try to look it up but even in the case if your layout of hosts, it would have referred you to 'attempting stuckz.cjb.net'
BASIC IP TROUBLESHOOTING
hard to explain .. easy to do)
1) First test physical (done, as you can ping other hosts)
2)Set baseline of bad condition by testing application connection to other hosts(done as you can telnet to other hosts and this shows your host is not blocking the application stack)
3) Focus on the host that is reflecting bad condition
a) ping that host(if yes then you have physical and basic host communication)If you don't then see if any other host can ping it.
b) telnet 'hostname' 'application tcp port' (if yes then firewalls are not an issue) you did this by directly pointing at the TCP port after hostname BUT check other TCP ports on the remote host to validate you can route to the offending host. Try SSH vs Telnet (seeing as anyone using telnet should be taken out and beaten with a wet taco)
c) IF you can test the offending host directly. Get to the host physically and 'telnet 127.0.0.1'. If this fails then I would surmise that the local telnet services are down. If they pass, check the firewall or routes on that host for return delivery back to you( ping would likly be quick way)
d) IF you can not get into the remote host. See if other hosts can. If other hosts can then the target host has some ACL in the router, firewall, hostaccess.deny, or TCP wrappper setting to stop your IP from gaining access.
