November 23, 201015 yr my server was running great connecting to all my pcs no problem. i switched from cable internet to dsl and in the process somehow screwed up my network. i cannot figure out what to do next. the unraid box wont show up on either of my pcs or my popcorn hour box either? any suggestions on what to do next? Im using a dsl router and a switch as well. the new network connection box came up on my pcs after adding the dsl and i think that screwed it up somehow

Im using a dsl router and a switch as well. the new network connection box came up on my pcs after adding the dsl and i think that screwed it up somehow It's likely getting a different IP address. Go to the console of unRAID and type in ifconfig and hit return. It should show you the current IP address.
November 23, 201015 yr Author when i type the ip adress i get from that screen 192.068.0.187 it says cant connect.
November 23, 201015 yr don't you mean 192.168.0.187? (ack made a typo here my self) also check if your other pc ip start with 192.168.0 and yeah check if you can telnet to the unraid als check the cabeling, and use another cable (just to make sure) btw did you reboot the unraid after you changed the network, maybe he still has an old DNS ip
November 23, 201015 yr Author i rebooted everything and now cant connect anymore. im very new to networking etc and i guess was just lucky that when i first built the server it hoooked up right away without anY tweaking. what are the settings that need to match in order for this to work. dont the ip adresses need to be all the same as well as the subnet or dns? were in unraid do i need to go using the acual server itself with the keyboard plugged into it to get all the setting i need to compare with the rest of my computers? thx p.s as i said im very new to this so please try to explain it as you would if your mother was trying to set this up
November 23, 201015 yr MS actually has a relatively decent article here that addresses the TCP/IP basics that you should know for setting up a network. The gist for what you need is all computers have to be on the same IP subnet. Each device must have a unique IP address. Each device must have a default route to get out of the network (router to the internet). Each device must have the IP address(es) of DNS server(s) for name resolution. To access the network settings in UnRAID log into the web interface, click on settings, and make any changes you need in the Network Setttings panel.
November 23, 201015 yr On your windows machine open a command shell (cmd) and type ipconfig and it will show what your windows IP is. Notice it's ifconfig on unix and ipconfig on windiws. Check if the subnet is the same on both. It's probably 255.255.255.0 You can also try pinging the windows machine from the unRAID console.

November 23, 201015 yr i cant log into the web interface anymore. it says the page is no lober available Assuming your network is setup as Internet <--> DSL Router <--> Switch <--> Computers or Internet <--> DSL Modem <--> Router <--> Switch <--> Computers Use the keyboard and monitor attached to the unRAID box and log in as root. Once logged in type ifconfig then press enter. Look for the IP address associated with eth0 eth0 Link encap:Ethernet HWaddr 00:25:90:0a:50:66 inet addr:192.168.1.51 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:83193956 errors:0 dropped:0 overruns:0 frame:0 TX packets:80016046 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1556875105 (1.4 GiB) TX bytes:742174664 (707.7 MiB) Memory:fe9e0000-fea00000 If it is not something in the 192.168.x.y or 10.x.y.z range you have IP addressing problems. If it is in the aforementioned ranges, use that IP address in your web browser to connect by putting in that IP address as http://IP_ADDRESS (http://192.168.1.51) for the example above). If your network is set up as Internet <--> DSL Modem <--> Switch <--> Computers You should disconnect your unRAID box from the switch immediately as if it is getting an IP address it is on the internet and unRAID is in NO way secure enough to be facing the wild of the internet. If this is the case, your previous cable modem functioned as router and your current DSL modem is functioning as a bridge and you need a router in the mix.
November 23, 201015 yr Author ill need to check when i get home. my dsl modem is set in router mode and then connected to a switch that then connects to my pcs/server and popcorn hour. my previous setup had the cable modem connected to a router then into the switch and all the devices into the switch. when i first changed the modem over everthing was working as far as local network but i was having issues getting on the internet so i reset my main pc. after that i could no longer acess my shares on that pc and the server no longer showed up in the my network section on that pc and the web menu no longer worked however i could still acess the server on my htpc and the popcorn hour. i then rebooted everthing and then could no longer access the server on any device. if it makes any diffrance eveything besides the server is working fine on my network now. i can see all the other devices
November 24, 201015 yr If you have multiple devices behind the router and everything else is working you shouldn't have a bridging/routing issue with the modem. Odds are after a reboot, your router handed the unRAID box a new IP address. Check the IP address on the unRAID server using the console (method described in previous post) and see if it is different. If that is the case, after you get the new IP address, log into the web management and set a static IP address so it will not change on you. You need to get the network block and subnet from the DHCP settings on your modem/router (assuming it is the DHCP server) or another computer and set things up on the unRAID box accordingly. Just make sure you give it an IP address that is outside the range the DHCP server is using (this will be in the DHCP server configuration for whatever device is acting as your DHCP server, probably your DSL modem/router) or you could end up with > 1 device with the same IP which makes things stop working Once you get the IP stabilized you can look into troubleshooting why name resolution does not work http://lime-technology.com/wiki/index.php?title=Troubleshooting#Name_Resolution
November 24, 201015 yr Author ok so i just got home and did some checking.i really have no idea what im doing so hopefully someone can help me with these numbers and were to go next. my server inet adress is 192.168.0.187 bcast is 192.168.0.255 mask is 255.255.255.0 my desktop is ipv4 192.168.1.101 subnet mask 255.255.255.0 defult gateway 192.168.1.1 my router is lan ip adress 192.168.1.1 subnet mask 255.255.255.0 dhcp server enabled wan ip adress 76.10.184.53 subnet mask 255.255.255.255 defult gateway 76.10.191.6 dns server 76.10.191.198 nat enabled what next? thx alot i really miss my server already
November 24, 201015 yr Your Server is on the wrong subnet or your pcs are on the wrong subnet. My server inet address is 192.168.0.187 My desktop is ipv4 192.168.1.101 My router is lan ip address 192.168.1.1 Look at the pattern 192.168 is correct but the server is on 0 but the pcs are on 1 Fastest way to fix is either change the server to 192.168.1.187 or router to 192.168.0.1 and reboot all PC's. Have fun. Thornwood
November 24, 201015 yr Your unRAID server and desktop are on 2 different subnets! Either you have VLANs set up with multiple DHCP servers, or you have your unRAID box set with a static IP to the wrong subnet. Log in to the console as root. Type cat /boot/config/network.cfg What I'm expecting is the result to be # Generated network settings USE_DHCP=no IPADDR=192.168.0.187 NETMASK=255.255.255.0 GATEWAY=192.168.0.1 If USE_DHCP is set to yes don't do any of the below, just post back that it is and we can go from there. To change the IP address on the fly type ifconfig eth0 192.168.1.50 netmask 255.255.255.0 then press Enter. I am assuming there is nothing else on your network with the IP address 192.168.1.50, if there is, pick another number and replace the 50 with it Now from your desktop put http://192.168.1.50 into the address box and press Enter. That should get you to the configuration page of the unRAID box. Use the instructions from one of my previous posts to reset the network settings to something appropriate to your network, then reboot the unRAID box. Everything should work when it comes back up.
November 24, 201015 yr Author it said no file found because i typed the wrong thing now i cant get back its just a blank area is there a way to get back to the login screen?
November 24, 201015 yr Author ok so i did what you said in the last post by changing the ip etc on the fly and can now get into the web menu again. what setting should i change now? thx again for the help i was really bummed out by this i just refreshed my network places and my shares are all back. im so happy right now. is there anything else i need to do so when i reboot it wont messup?
November 24, 201015 yr Just go to the settings page, then set the following the Network settings panel Obtain IP Address Automatically = NO IP Address = 192.168.1.50 Netmask = 255.255.255.0 Gateway = 192.168.1.1 Obtain DNS Server Automatically = NO DNS Server 1 = 192.168.1.1 Then click apply. Stop the array, and reboot the server. When it comes back up log back into the web interface to make sure that is working. Log into the console and type ping google.com to make sure DNS resolution is working. If not, change the DNS Server 1 setting to 76.10.191.198, apply, reboot, try again. Once everything there is working, you can open a command prompt on your windows machine and type ipconfig /flushdns nbtstat -R ping SERVERNAME but change SERVERNAME to whatever you have your server named (default is tower) to test netbios name resolution. If you get replies name resolution works, if not see this article on the wiki for troubleshooting.
November 24, 201015 yr Author im just transfering some files over right now so ill give that a try shortly. thx to all for helping me out. i would have been messing with this for days.
November 24, 201015 yr Author im just rebooting now when you say to log into the console you mean on the unraid server itself or does it have to be using putty to ping google?
November 24, 201015 yr Internal networking is independent of DNS resolution. Use whichever is more convenient
November 24, 201015 yr Author after pinging google all packets were recieved. pinging my server does not want to work. i called it THE VAULT so is it possible the space in between is messing it up? does it matter now that its all working ok?
November 24, 201015 yr Spaces are bad! Try changing it to The_Vault or TheVault. Does it really matter? Not if you want to address it by IP address than its name, but I find remembering and typing out IP addresses cumbersome. Also in between changes to names/IP addresses it is beneficial to run (on your windows box) ipconfig /flushdns nbtstat -R before you ping again to make sure your system queries the network for the current info. Don't want to get everything set right and not get a response because windows has latched onto a netbios name/IP. Once everything is configured, you don't have to worry about flushing the resolver cache or the netbios table.
