We’re raising the bar for tattoo ink safety. Our ink is made from ingredients that are FDA-approved for medical use and tested for biocompatibility. Hope this saves someone some time and frustration in the future. Unlike traditional tattoo ink, our bodies naturally remove Ephemeral ink over time. Typically this means that both the server and the client will need to specify non-default settings, and there may be. (like an SSH server) on a non-default port (like TCP port 80), this will work. The ephemeral range can vary between OS’s and distributions so do your own due diligence here. This range is used for private, or customized services or temporary purposes and for automatic allocation of ephemeral ports. So we have now moved our mediasoup webRtcServer ports outside this larger ephemeral range. Node 6523 webapp 1033u IPv4 46295 0t0 TCP :40000->:6379 (ESTABLISHED)Īnd this would only happen randomly when the OS selected such a port, and we failed to initialize the worker prior to trying to hit redis (or whatever external service that needed TCP). ![]() to redis: lsof -i :40000ĬOMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME What this meant is that it would use ports in this range when establishing outgoing connections, e.g. They appear to have a much larger ephemeral range than some other distributions and larger than what you might find when googling for what the usual ephemeral range is: ~]$ cat /proc/sys/net/ipv4/ip_local_port_range It turns out that port 40000 is in the “ephemeral port range” for these EC2 instances. We thought maybe we had a race in how we initialized workers, but eliminated that. Uv_listen() failed : address already in use We started randomly getting errors like this: We kept our webRtcServer ports in the low 40000 range as the mediasoup demo is setup (and how we have been setup using just the normal webRtcTransport range for some time) and setup workers to use a separate range. We recently moved to using the new webRtcServer. ![]() Just dropping this here in case someone else hits this problem. ![]()
