slint and transmission-cli questions

Hello Jude,

I quote below the main part of the answer I received from B Watson.
He is not registered to this list so please CC him in your further
posts on this topic.

I confirm that for Slint as well, and we do have the sysctl command
that can handle this file, as noted in "man sysctl"

So to avoid these errors or warnings:
> [2018-05-03 14:39:36.371] UDP: Failed to set receive buffer: requested 4194304, got 425984
> [2018-05-03 14:39:36.371] UDP: Please add the line "net.core.rmem_max = 4194304" to /etc/sysctl.conf
> [2018-05-03 14:39:36.371] UDP: Failed to set send buffer: requested 1048576, got 425984
> [2018-05-03 14:39:36.371] UDP: Please add the line "net.core.wmem_max = 1048576" to /etc/sysctl.conf
I wrote this as root:
echo "net.core.rmem_max = 4194304 >> /etc/sysctl.conf
echo "net.core.wmem_max = 1048576" >> /etc/sysctl.conf
sysctl -p

The latter command's output is, as expected:
net.core.wmem_max = 1048576
net.core.rmem_max = 4194304

Then this command:
transmission-cli -w /tmp http://www.slackware.com/torrents/slackware64-14.2-install-dvd.torrent
ran without errors.

Let us know if that works for you as well.

Greetings,

Didier Spaier

>> Anyone running transmission-cli on slint?  I get a couple errors when it starts up I think I can turn off by disabling port mapping with the -M option.  Apparently transmission-cli expects to be on systemd machines because both error messages want /etc/sysctl.conf to be updated and have lines added to it.  I don't know what to do for system v systems.  Also, I don't know what port mapping would get me if it were enabled as well as disabled.  Transmission-cli runs after these errors though.
