OK... heres my setup... On a private server, Per friends request I have two separate virtual machines, both ubuntu 10.04 64bit linux servers. With a Windows 7 64bit host, Connected directly to a router.

lets refer to the systems by their host names.

WebServer; (Ubuntu 10.04 Server x64, setup with SSH, LAMP, and PROFTPd)

    - Network adapter: VMware NAT translation;
    - IP: Static
    - Address:
    - Netmask:
    - Network:
    - Broadcast:
    - Gateway:
- Resolve.conf: Nameserver<br/>
- IPv6: Disabled

Ports forwarded to this machine:

- HTTP Port: 80<br/>
- SSH Port: 22<br/>
- FTP: 21<br/>

IRCServer; (Ubuntu 10.04 Server x64, setup with SSH, LAMP, and UnrealIRCd \w anope):

    - Network adapter: VMware NAT translation;<br/>
    - IP: Static<br/>
    - Address:<br/>
    - Netmask:<br/>
    - Network:<br/>
    - Broadcast:<br/>
    - Gateway:<br/>
- Resolve.conf: Nameserver<br/>
- IPv6: Enabled (disabled on WebServer because I was getting flooded with no 
IPv6 Routers Present errors along with the disconnection)

Ports forwarded to this machine:
- SSH Port: 2222
- UnrealIRCD: 6667


- Windows 7 x64<br/>
- 8GB Ram<br/>
- 2.2GHz Phenom 9550 Quad-Core<br/>
- Marvell Yukon 88E8071 PCI-E Ethernet Controller<br/>

My problem is that randomly, One of the servers would loose all connection. (hardly ever happens to IRCServer, Not sure what causes it).
WebServer will loose all connection often when I try to login with FTP, (FileZilla from Desktop, connecting to
No additions to dmesg, ifconfig eth0 says its still up, and its ip is (.8 for IRCServer), and if I $host it fails with the error:

;; connection timed out; no servers could be reached

Note: I thought it useful to add that, to fix this, all I have to do is sudo /etc/init.d/networking restart

Am I missing somthing here? I am normally quite good with this kind stuff, Have been using Ubuntu for 4+ years. And Google even longer, I have a feeling its right in front of me, but I don't see it.

Another note: Nothing in the syslog, And its not the adapter as its the same software adapter for both systems, and when WebServer goes down, IRCServer remains connected

You shouldn't really cross-post exactly the same question to multiple sites like this.… – David Spillett Jun 3 '11 at 2:00
