avahi-daemon and “.local” domain issues
I have a Ubuntu 16.04 based HTPC/Media Server that’s running 24/7. As far as I can remember using an official Ubuntu distro, I’ve always had issues with the avahi-daemon. The issue is pretty often discussed online. Some people decide to just delete daemon, however, I actually need it as I’m running a CUPS server and use Kodi as my AirPlay reciever.
ping displays “Name or service not known”
I am running Arch Linux on a Raspberry Pi.
Host lookup that respects /etc/hosts
Utilities like host and dig let you see the IP address corresponding to the host name.
Why does Chromium not cache DNS for more than a minute?
I use Chromium and have problems with the DNS not being cached for the time that I would expect. Take the example.com domain. According to the DNS settings, this domain should be cached for another 26151 seconds:
No domain defined in /etc/resolv.conf
I see more and more servers that have no domain defined in the /etc/resolv.conf file.
Only a search entry.
In what cases is this setup used ?
Are there any cases where it must not be used ?
DNS lookups sometimes take 5 seconds
I have a VM running Debian Wheezy on which some hostname lookups take several seconds to complete, even though the resolver replies immediately. Strangely, lookups with getaddrinfo() are affected, but gethostbyname() is not.
Why doesn’t systemd-resolved use my local DNS server?
I’m using a local BIND9 server to host some local dns records. When trying to dig for a local domain name I can’t find it if I don’t explicitly tell dig to use my local BIND9 server.
How can I check if my DNS server is working?
This case scenario is for a router with embedded linux, but I think
the answer could be the same for any Linux system.
Incoming/Outgoing seperation for VPN
My situation is that I want all my outgoing connections from my Debian server to pass through a commercial VPN service I’ve subscribed to, but I still want to run public-accessible services on this server, and not have them pass through the VPN.
