I have multiple IPv6s I need to know what works, on my network they all work, but I need to know what to use for my AAAA record. ip address link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s25: <BROADCAST,MULT
I've had limited success in having LXC instances acquire an IPv4 address. It has worked at creation, but if I reboot the host, all addresses are lost. Host Ubuntu 21.10 Client version: 4.21 Server version: 4.21 Image Ubuntu 21.10 tgl@electra:~$ lxd version 4.21 tgl@electra:~$ lxc version Client version: 4.21 Server version: 4.21 tgl@electra:~$ lxc list +----
Recently upgraded to Debian 11 bullseye , and our Docker swarm node s had trouble talking to each other, and started dropping some connections. After much Google-ing, we stumbled on these threads: https://github.com/moby/moby/issues/41775 https://bugzilla.redhat.com/show_bug.cgi?id=1987108 And specifically this command, which fixed the issue: ethtool -K <
I want to list all the network namespaces on my Linux machine. So far I found two recommended ways to do this: ip netns list And lsns --type=net Unfortunately both commands do not list all the namespaces! The first only lists the namespaces found in /var/run/netns and the second will only find namespaces with at least one process running in it. Docker for ex
In my internal work network, whenever I launch dig against a particular hostname, I get result similar to this: ;; ANSWER SECTION: some.internal.host.com. 10 IN A 10.210.54.121 If I keep spamming the same dig some.internal.host.com command, the response always has a single A record, but the IP address is changing between calls. I assume it is some form of lo
I always thought that the default gateways has to be on the same network as the server/client trying to connect to the internet. However today I rented a server from Hetzner and the server is able to connect to the internet even though, as it seems to me, the default gateway is definitely not connected to the same network. Also the netmask seems to be set to
I am trying to configure wireguard to work as a VPN server. The main problem is, that the gateway only forwards the VPN server ip to other server, not my client IP. My setup is the following: - server A (10.10.0.4) / CLIENT (10.10.1.3) -> wireguard server (10.10.1.2) -- (10.10.0.2) \ - server B (10.10.0.3) The wireguard server runs on a machine with two i
Networking Trade-offs in Source Engine In the original Source Engine networking model, clients render remote entities in the past to ensure smooth movement via interpolation. This process relies on the cl_interp and cl_interp_ratio variables to determine how many snapshots are buffered before rendering. A primary design conflict arises when balancing the per
The story so far: I have installed Postgres on my Linux based desktop (HOST). I have created a test database, with test data, on HOST. I have added to the end of the pg_hba.conf file on HOST: host samerole all 0.0.0.0/0 md5 I have added to the end of the postgresql.conf file on HOST: listen_addresses = '*' I have installed PGAdmin4 on the Linux virtual machi
