See the Wikipedia article about the Name Service Switch for more context on this. Unix systems have a notion of host name that isn't related to the network subsystem.
That name is what the hostname command shows and what turns up in logs. For your sanity, you had better make sure that this host name agrees with what your neighborhood DNS server says, and with what if anything your system thinks it's called. In fact, DNS names are not associated with machines, but with network interfaces, so your DNS name will be associated with one of your network interfaces.
On machines with no actual network connection, the host name should be associated with the loopback interface. You can change it at runtime with the hostname command; this is done early in the boot process.

How did you resolve it??? It is not related to the Router in my WiFI home network because other devices are working fine. The laptop worked fine up until July 22 On that and the following day, two critical updates have been automatically installed at 3 am.
Since then, it has been a constant struggle up until one hour ago! I have restored the machine to an earlier time, reset lots of time wlan connections, added ports to the Firewall to try go through the IPs.
I have got another automatically downloaded update pending and I am shivering, no joke.Welcome to LinuxQuestions. You are currently viewing LQ as a guest.

Kindly help! Depends on how you configured the virtual network adapter but you are using DHCP so although you have added an entry in the hosts file it may be different than the actual address. Also whatever service is running on port may only be configured to listen on localhost. Many thanks Michael for the quick reply! I had tried adding " Thanks and regards Kavitha. Attached Files nslookup debuggig. What local DNS server are you running?
If it is not then nslookup as far as I know will never resolve a local hostname. Thank you Michael for your reply!
No, I am not setting up any DNS server! I will try to give more information! Thanks and Regards Kavitha.
As I already commented here but with no answer yetI use docker-compose. The documentation says, compose will automatically create a hostname entry for all container defined in the same docker-compose. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.
I also tried to add links to my container, but nothing changed. Docker 1. On a user defined network, Docker will use the internal DNS server. This setup allows bridge, custom and overlay networks to work in a similar fashion. So an overlay network on swarm will populate host data from across the swarm like a local bridge network would. The "legacy" setup was maintained so the new networking features could be introduced without impacting existing setups. For example, with a web and db service defined, and the db service scaled to 3all db instances will resolve:.

Troubleshooting: Can’t Resolve Hostname
It only takes a minute to sign up. I have a user on Windows 7 that is trying to access a local server with a DNS name of windows. We have two internal DNS servers. Every now and then, the user can't access the website at windows.
If I ping it, it says it can't resolve the host name.
Windows 7 can't resolve host names
I flush the DNS cache, and then when I display the dns cache it has the following:. Yet if I use nslookup, which by default queries the primary DNS server our internal one and I query windows. So why can't Windows resolve the hostname using ping, but it can when using the nslookup tool? And how do I fix this? It appears from what you're saying that the request for windows. The nxdomain result is then cached by Windows' DNS client, and thus used for any retries with a web browser, ping etc. The reason ping can't resolve the hostname but nslookup can is because nslookup a low-level tool that bypasses the Windows DNS client.
It uses whatever DNS server you tell it to the first one by defaultand does the query on the fly. The Windows DNS client however will only do queries for entries that are not in its cache or have expired.
Otherwise it returns the cached result. Perhaps it could not resolve the local server recently due perhaps to being on another networkperhaps the local server was returning errors. I can't imagine there being any valid performance reasons, and as far as redundancy goes two is enough on most networks if not add a third.
The results of nslookup differ from that of ping because of nslookup idiosyncracies and bugs. They are not really relevant to your main problem, however, which is that you've violated the rule that your fallback proxy DNS servers must provide the same view of the DNS namespace as your principal one.
It would seem that yet another system administrator has fallen foul of the My ISP provides and documents it, so I must use it. I had the same problem on my development machine. I could also use nslookup but had to manually change the server via server X.
X to get DNS resolution. I was able to resolve the issue simple by deleting the DNS record and run the flushdns and registerdns commands and that fixes it. The DNS did not delete the record after the lease has been expired and didn't get renewed which couldn't resolve the name because it'sold for it.
I tried this but it didn't help. Check the contents of both.

This is the old way of doing things and assumes your host does not have NetworkManager running. NetworkManager will attempt to manage these files for you, and if you edit them by hand you can find them overwritten.
This is likely what happened since the symptom appeared after reboot. Based on your reslove. You can add this to your reslove. So your file should have the entries listed below.

Is this your first reboot since setting this server up? It's also worth mentioning that the intended audience of this site is professional system administrators operating in a professional capacity. For more information about this site, please take the tour! RHEL is extremely well documented. If you intend to manage this server yourself, you would do well to familiarize yourself with the docs as they will be very helpful.
