comment svnserve seems to write files as root. How can I give access to the same repository via svnserve and apache?
I am just curious as to what is not elegant about modifying the startup script to make the daemon run as the correct user?

comment Computer gets IP from DHCP server but has no internet connection
sorry missed the eth1 above. The problem is your ip scheme (and that you have 192.168.20.1 on both eth0 and eth1). Change your subnet on eth1 and you should work fine.

also you can't have 2 dhcp servers giving out different information on the same Layer 2 network Just doesn't work and int looking at your config are you trying to NAT on the same interface, it will not work. what I would do is this. move the 6 worker nodes to a different layer 2 network, and hook them into eth1 on the head node. Give them a different RFC 1918 address (10.x ) and then all of your stuff above would work. BUt with only 1 interface and the overlapping subnets/ 2 dhcp servers it will not work.

what is subnet mask on the 192.168.1.x network? if you are getting an ip of 192.168.20.1 from that network the subnet mask is probably 255.255.0.0? and it looks like you are trying to nat with overlapping subnets. if you change your downstream dhcp config to use a different set of RFC1918 IPS does it work (10.10.0.0/24 for example).

comment Moved IP addresses to other server, no network internally anymore
can you ping the new ip from the server they are on? if yes, have you checked the arp tables on the server (arp -a) to make sure they can see each other at Layer 2?

comment How to set up port forwarding on a NETGEAR ProSafe™ Gigabit 8 Port VPN Firewall FVS318N?
@marcgg what I mean is if you are on 192.168.1.x and you are trying to go to external.ip.addr:3000 some NAT devices cannot hair pin the traffic so the nat might be working fine from oustside (As demonstrated by the your test, but not from inside. AKA hairpinnig since it the router/firewall/etc is basically talking to itself.

Are you trying to test it from behind the firewall? A bunch of firewalls will not hairpin traffic?

I at a loss, it should work as is, normally when it doesn't there is something else taking precedence.

comment Reverse proxy apache and nginx
do you have a NameVirtualHost *:80 in your apache config?

comment Reverse proxy apache and nginx
there is some other host in your apache config that is overriding this config, you'll need to find it. But do you actually need to run apache? why not just let nginx listen on port 80?

comment Reverse proxy apache and nginx
either use name based virtual hosting, or remove the config pointing to docroot, since apache will use the first config it finds as the default). so assuming you have name based virtual hosting setup. adding servername domain.com to the above should make it work.

comment Virtual router for virtualisation
You can add a vm running pretty much any os that can forward packets between interfaces and build a router. All of my firewalls/test routers that I run Virtualized are just OpenBSD VMS. So it is totally possible (No idea how to use windows to do it though)

and you are setting the port in putty as well? Did you enable the centos firewall when you installed the OS? check here wiki.centos.org/HowTos/Network/IPTables for more info.

welcome to a server on the internet. There are lots of bots out there that scan the net looking for port 22, and then when find one try tons of random user name/password combos looking for week passwords. once you edit the sshd_config and restart ssh it should be listening on that port netstat -an | grep 8022 should show it. I don't really know EC2 as I have my own servers, but in their firewall you would need to allow inbound 8022 assuming you used that port.
