Continous operation relies on mosh keepalive packets without interruption, as.Started mosh-server waits for 60s (default) for mosh-client to connect.34730 is the default port for -c/-client-port and -s/-server-port opts in.Both mnb.so and mosh-nat only work with IPv4, IPv6 shouldn't use NAT anyway."mnb.so" used with LD_PRELOAD is that mosh-nat-bind.c wrapper, which can beĬompiled using: gcc -nostartfiles -fpic -shared -ldl -D_GNU_SOURCE mosh-nat-bind.c -o mnb.so.MOSH_KEY=rYt2QFJapgKN5GUqKJH2NQ mosh-client 34730Ĭlient% MNB_PORT=34730 LD_PRELOAD=./mnb.so \ Making connection using these two is as easy as with stock mosh above: UDP port, which was used as a dst by mosh-server wrapper above: mosh-nat-bind.c And a wrapper for mosh-client to force its socket to bind to specified local.Which server will then be started: mosh-nat One for mosh-server to send UDP packet to the client IP, using same port on.With hole-punching, two additional wrappers are required with the current mosh MOSH CONNECT 60001 NN07GbGqQya1bqM+ZNY+eAĬlient% MOSH_KEY=NN07GbGqQya1bqM+ZNY+eA mosh-client 60001 So all that's needed to connect in a simple case is: Mosh is generally well-suited for running manually from an existing console, Once mosh-client establishes the connection and keepalive packets will startīouncing there all the time, it will be up indefinitely. NAT on the router(s) in-between the two will see this exchange as a serverĮstablishing "udp connection" to a client, and will allow packets in bothĭirections to flow through between these two ports. Connect to that with mosh-client, using client:34701 as a UDP source port.Start mosh-server, listening on server:34700.Send UDP packet from server:34700 to client:34701.Pick some UDP ports that server and client will be using, e.g.Punch hole in the NAT for these before starting both. Server and client IPs, pre-pick ports for mosh-server and mosh-client, then There is much easier way that works perfectly for most cases - knowing both Wireguard) from destination host (server) to a client, and use mosh over that.īut that's some extra tools and configuration to keep around on both sides, and One obvious way to make it work, is to make some tunnel (like OpenVPN or Mosh, which didn't get any traction so far, unfortunately: There are quite a few long-standing discussions on how to solve it properly in What's lacking in super-laggy multi-hop ssh connections forwarded back-and-forth Which sucks, because its performance and input prediction stuff is exactly Pwnat, etc, but for mosh UDP connection it's not that trivial. There are way more tools that happily forward TCP ports than ones for UDP.Ĭase in point - it's usually easy to forward ssh port through a bunch of hostsĪnd NATs, with direct and reverse ssh tunnels, Prox圜ommand stuff, tools like Upgrading ssh to mosh with UDP hole punching to connect to a host behind NAT Generated for random outdated clients and add email for notifications (if not c rsa-2048 -c ec-384 to also have cert with rsa key Options for all kinds of cert and account settings, e.g. There are bunch of other commands mostly to play with accounts and such, plus "" too, not doing any extra work there either.Īdd & systemctl reload nginx to that, put into crontab or. to get signed cert for, doing all the generation, registrationĪnd authorization stuff as necessary, and caching that stuff in acme-cert-tool.py -debug -gk cert-issue \ Py crypto toolbox (cryptography.io), and does everything through a single Wanted to find some simple python3 script that's a bit less hacky thanĪcme-tiny, not a bloated framework with dozens of useless deps like certbotĪnd has ECC certs covered, but came up empty.Īcme-cert-tool has all that in a single script with just one dep on a standard Implemented it a few months back when setting-up TLS on, and wasn't satisfied byĪny existing things for ACME / Let's Encrypt cert management. Tend to mention random trivial tools I write here, but somehow forgot about this Acme-cert-tool for easy end-to-end https cert management
