linux sysadmin
this problem doesn't break anything but i'm bewildered as to why it is happening
i added lines to /etc/services to help me remember what port does what when i'm looking at the output from ss (formerly known as netstat). for only some of the custom entries, it doesn't work
getent services 42069 works
python -c 'import socket; print(socket.getservbyport(42069)) returns iocaine
but ss -at shows 127.0.0.1:42069
between other entries that do use my names
