CentOS - Oct 2013 - CENTOS 5 incoming SFTP

Hello,

I have a CENTOS 5 box that can reach the internet and can ping to/from all
windows system on my home network.  The catch is that I can not connect to
the box using SSH from any windows machine, though they can easily ping the
linux box and vice-versa.

Suggestion of a possible solution would be most appreciated.

Many thanks!

John

Is there a firewall running on the Linux machine, and if so, is it 
allowing tcp port 22 through?  Are you able to ssh from other Linux 
systems on your home network (if there are any) or have you only tried 
sshing from Windows systems?  Is sshd running?

That's obviously not true or just half of the story. Did you actually try 
*sshing* in? Your title mentions sftp, not ssh. So, what software are you 
using to connect? I would normally recommend using SCP (and not sftp) with 
WinSCP. If you do that you can have the sftp subsystem of OpenSSH shut 
off.

others have mentioned it as well, it sounds to me like there's a local
firewall (probably iptables) running on the linux box.   Although I thought
the default in the 5 series of redhat/centos was to leave port 22 open.
it could also be that you don't have the ssh daemon turned on/possibly even
installed (?)

I'd make sure you have ssh turned on (from the linux machine, ssh to
localhost, telnet localhost 22, ps -ef | grep sshd, service sshd status,
chkconfig --list | grep ssh )
if all that works and looks OK, then try turning off firewall (service
iptables stop)
then try to ssh in from your other machines
if that's ok, then back to the linux machine's console and do service
iptables start
iptables -I INPUT -s ${cdir of your lan[1]} -p tcp --dport 22 -j ACCEPT
service iptables save
and I'd think you should be set.


[1] if your LAN is 192.168.0.0 with a netmask of 255.255.255.0 the CDIR
would be 192.168.0.0/24, not sure how much you've dealt with that.   googl
will be your friend if you have an odd netmask.

some of these options may be off, I don't use centos 5 much these days and
all I'm putting in here is from memory, so I might be missing some stuff,
but I think it's reasonably close.
