Cannot see my SME server on network: Have Gamerlounge d-link router

Hi everybody,

I was wondering if anyone has had the same problem as me or would know of how to better diagnose this networking problem.

I have installed SME server on to a small box lieing around.
Went through the install stages and made sure the
1. ip address i assigned it was not being used
2. Was on the same subnet
3. Had the right router details for DNS etc.

I cannot seem to ping any of the machines in my network.
Neither my machines can see the SME box.
THe Internet test fails on the box.
It doesn't appear on the router ( Gamerlounge d-link router) as a machine on the network.
Yet the light on the router is statically on (Not flashing)
And the routers ip address does appear in some of the logs on the router in the active sessions page.

I have ifconfig and noticed the ipaddress etc everything is correct but yet it cannot be seen.

I have set the same machine up in a VM and it works perfectly.

I have plugged in other boxes and they are fine its just when i use SME on a physical piece of hardware it does not come on the network.

Does anyone else have this trouble?

And can anyone recommend any other commands /tools that i could try from the command line to query this problem?

Many thanks again for all your help and the time in reading this mail.

To be clear, the SME server is connecting into one of the ports on the Gamerlounge d-link router, and the other machines are connecting into other ports on the same router, is that correct?

A few things I might try to look for:
- Have you tried using a different cable?
- does the router block MAC addresses?
- what does the route table look like on the server (~$route)?
- is the server using dhcp to get an address (you said you assigned it one that was not used)?
- can you ping the ip address of another machine on the network without using a hostname?
- is there a default firewall, hosts.deny, or any other such setting that may block access?
- what happens with ~$dhcpcd -d?
- Does ifconfig show packets being tx and rx? Any errors?

Good luck.

Thank you so much for the advice and help.

I have been looking over this the past few hours and here is what I have so far.

1. I tried a different cable and with different cables there is no problem.

2. I reinstalled the SME server and when I type in the machines IP address ( it does load up the default blank website "This Web Site is under construction" So i know my windows box can load up the SME empty website. The router shows the website sending packets in the active session logs

Internal Protocol External NAT Priority State Dir Time Out UDP 62139 130 - Out 282 TCP 49739 169 LA Out 229 UDP 53076 130 - Out 273 TCP 49738 169 LA Out 229 UDP 58592 129 - Out 273 TCP 49737 169 LA Out 229 UDP 49671 130 - Out 273 UDP 24882 130 - Out 204 UDP 58363 130 - Out 204 UDP 22226 130 - Out 204

1. I cannot ping the SME Server from any machine.
2. Cannot open up the SME Server admin page (
3. The SME server cannot ping the router or any machine on the network. (Destination Host Unreachable)

So i guess before i start tackling routes I should atleast see if machines on the same subnet can atleast talk to each other....

My windows box

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Realtek RTL8168B/8111B Family PCI-E Gigabit Ethernet NIC (NDIS 6.0)

Now my SME Server

eth0 Link encap:Ethernet HWaddr
inet addr: Bcast: Mask:
RX packets:5047 errors:0 dropped:0 overruns:0 frame:0
TX packets:6789 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:2236260 (2.1 MiB) TX bytes:467322 (456.3 KiB)

lo Link encap:Local Loopback
inet addr: Mask:
RX packets:2663 errors:0 dropped:0 overruns:0 frame:0
TX packets:2663 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:223216 (217.9 KiB) TX bytes:223216 (217.9 KiB)

My router which is what both of these boxes are connected to

address is

Mac Address Filtering has been switched off and the ipaddress that i picked for the SME server is not used by any other machine on the network

route output is

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface U 0 0 0 eth0 UG 0 0 0 eth0

With my limited knowledge. I thought that if 2 machines are on the same subnet they should be able to talk to each other? I fugre that if i can get two machines on the same subnet to be able to talk to each other I can then start to address the routing issue on the SME server so I do not get what i am missing?
Any help or ideas as to what i can try/lookup next would be gratefully appreciated.

Many thanks again for all your help.

trie to put a intel chipset network card in your sme server and reconfigure the ip address on the intel network card

or jou can trie a d-link card
