Fedora 37 has done away with the trickle tool.
trickle was used to limit the bandwith of a network connection.
For example I used it to limit the backup tool duplicity so that the backup would not occupy my entire connection.
Is there a replacement tool available in Fedora 37?
Wondershaper looks like an alternative, but the repo owner himself says that "As discussed, I don’t use wondershaper much myself anymore. So it’s just random pings and notifications that alert me to the project. " Last commit is also from October 2021. Not sure I would want to help maintain such a package.
I will ask at OpenWRT. They should know a thing or two about network shaping. I will report back here if they have some nice suggestions.
wondershare works on a per-interface basis, not on a per-application basis. So no trickle replacement.
I asked on the OpenWRT irc channel, but there are other methods available for restricting traffic on a specific port. I guess application level are not so much of an issue there, as command line tools such as sftp, wget, curl etc all support bandwith limiting out-of-the-box and services on dedicated ports can be restricted via firewall. However, the suggestion with the sftp options solves the issue for my case, as my duplicity configuration uses sftp and I can simply add a parameter there.
