May 9, 20179 yr Dear friends... First of all, thank you a lot for your help. I'm fighting against a network problem in two different servers some time ago, and after a lot of work trying to solve it, I'm not able to solve and I need your help. And please, sorry for my poor english... I have two servers, the first, HDSERVER, running from 2011, has been updated, I can't remember what was the first unRAID version I used, until today, that is running version 6.3.3. I have never had any problem until one and a half months ago, or so... This server is a personal creation. The second server is HDSERVER2, running from last months of 2016, updated a couple of times, until today, that is running version 6.3.3. Also without any problem until one and a half months ago. This server is a HP N54L. The problem, is the same in both servers: 1. After booting, I have perfect LAN conectivity, but I cannot update plugins nor update the media libraries in docker plex. There is no internet connection in both servers. 2. I need to deactivate docker, and in network settings I need to change network to bridged, and next, change to not bridged again. 3. I activate docker, and network begins to have internet connection. This problem has appeared about one month and a half ago. I've tried with different network cards in both servers, and the problem was not solved. Same behaviour. So I have prepared a test system, installing a fresh 6.3.3 version, with trial key, and one hard disk. I have installed docker plex, some plugins I use in both servers, and this system has no problem. I always have LAN and internet connection. I don't know what more can I try. Nothing I have tried has solved the problem. I've attached the diagnostics with servers just booted, and after stopping docker, changing network configuration and after starting docker again, of both servers, HDSERVER and HDSERVER2. Also system logs. I've attached too the diagnostic of test system TOWER just after booting, also system log. If you need more information, please let me know. Very very thanks in advance.

May 9, 20179 yr Without looking at the diagnostics, the obvious question is are they both set to have the same IP address (in either unRaid's settings or in your router)? If only one is on at a time does it have full connectivity? Try setting static DNS addresses of 8.8.8.8 and 8.8.4.4 in network settings.

Every server has his own static IP and I use google's dns. And the problem occurs with one server on, or with the two on. Thanks again !!!
May 9, 20179 yr Can you tell us what each servers network settings are? How many routers do you have on your network?

I attach network settings of the two servers and the test server. At home I have a wimax internet connection, with a Ubiquiti LiteBeam M5, that is connected to an TPLINK 8 port gigabit switch, for some equipment I have in my home cinema room. From this switch, goes one network cable that goes to a DLINK 8 port gigabit switch that connects to my pcs and my servers. Everything has always worked well, until one month and a half ago, approx. I have not changed nothing in the servers nor in the network installation. It's very strange for me. I can not find a logical explanation. Thanks for your help.
May 9, 20179 yr Is it possible some other device or computer on the network has the same IP as one of your servers?

One thing: I have seen that when the network configuration is restarted in the servers, either by changing the operating mode (bridged - not bridged), or the IP address, once restarted, everything works correctly. Thanks again...

May 9, 20179 yr Is there a DHCP-Server on your Network? And if yes, check if the DHCP Adress-Pool is not overlapping the static adresses.

I will have to talk with my internet provider. I cannot access to the LiteBeam configuration. Thanks for your help...
May 9, 20179 yr Are the static IP addresses you are using on the two servers in the same subnet as other devices on your network that do have Internet access? Since you say you do not have access to the router you might consider going with DHCP and see if that allows both to access the Internet.

HDSERVER --> 192.168.1.100 HDSERVER2 --> 192.168.1.101 All my devices have IPs 192.168.1.xxx I will try using dynamic IPs with DHCP. Thanks !!!
May 9, 20179 yr Also, consider commenting out your echo statements in the go files until you get the network issue resolved.
May 9, 20179 yr Author Hi all !!! I finally solved the problem, but still don't know the origin. I have tried restarting the network settings, and it worked !!! I've added to the GO file the next lines, before starting emhttp: # Restart network configuration logger -t "$0[$$]" "##### Restart network configuration. #####" /etc/rc.d/rc.inet1 stop /etc/rc.d/rc.inet1 start logger -t "$0[$$]" "##### Network configuration restarted. #####" The command /etc/rc.d/rc.inet1 restart returns errors and doesn't work: Not enough information: "type" argument is required Error: argument "up" is wrong: Device does not exist What happends to "restart" option What I said. Solved, but I do not know why it happens. Thank you all for your help !!!

Didn't read the whole thread, but can you post your diagnostics if not done already? Edited May 9, 20179 yr by bonienl

I know, but the "start" command only gives up the network interface, and then the problem starts too. The "stop-start" commands have made the trick. The diagnostics files are in my first post. Thanks in advance...
May 9, 20179 yr You should remove the line from your go file echo nameserver 192.168.1.1 >/etc/resolv.conf It overwrites the DNS settings of your network page (8.8.8.8 and 8.8.4.4). If you want your local gateway to act as DNS server, just enter its address in the network settings. When static entries are used then unRAID will generate the resolv.conf file.

You are my hero !!! I've tried what you suggested and it works !!! Is strange, but that line is in the GO file from a very long time ago. I don't know why now that line has become problematic. I will think if something has changed, but I've not touched the servers configuration. I'm sure about that... Thanks again !!! Edited May 9, 20179 yr by alikuenkano
