SSH/Apache on Virtual machines [message #25416]

I am trying to get a set of VMs to run SSH / Apache

I have VM 2010 at ip 10.0.20.10, it runs SSH & Apache on ports 22 and 80 respectively.

with the following:

iptables -t nat -A PREROUTING -p tcp -m tcp --dport 2010 -j DNAT --to 10.0.20.10:22
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 2011 -j DNAT --to 10.0.20.10:80

I get this:

Chain PREROUTING (policy ACCEPT 72 packets, 9800 bytes)
 pkts bytes target     prot opt in     out     source               destination
    1    52 DNAT       tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           tcp dpt:2010 to:10.0.20.10:22
   24  1216 DNAT       tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           tcp dpt:2011 to:10.0.20.10:80

Now, for some reason the connection doesn't go through with Apache, but works perfect with SSH.
Apache is running, but I can't even connect from the main node:

#telnet 10.0.20.10 80
Trying 10.0.20.10...
telnet: connect to address 10.0.20.10: Connection refused
telnet: Unable to connect to remote host: Connection refused

What should I look at?

I am assuming you mean httpd (not mysqld)

I set httpd.conf to listen to the virtual server's IP.

From the main node, I can do

telnet 10.0.20.10 80

and it works. But, from the outside, it doesn't.

However, when I check with

iptables --list -n -v -t nat

I can see the packets coming from the outside, but it still does not work.

weird! now it is running, same setup... after a reboot...

Apache was listening, I could telnet to it from the main node, but not from 'the outside world', until the reset
