Way too many log entries from connmand in s6 log

Hi guys, how can I tell either connman or s6-log to log less? The log file is already 9200 lines long after only 6 minutes!!
The bulk of entries look like this:
Code: [Select]
2026-01-10 15:20:35.066869089  connmand[636]: wlan0 {TX} 16696 packets 2136090 bytes

I'm really not interested in these kind of log entries, so how can I get rid of them?

Go to your services' file under /etc/s6/config and create/edit a line starting with DIRECTIVES. Take the default n3 s2000000 T if it's not present, and use a word (actually a regular expression) prefixed by - in order to skip it. For instance.

Code: [Select]
/etc/s6/config/connman.conf
===================
DIRECTIVES="n3 s2000000 T -wlan0"

or (actually using regular expressions - skips lines containing {RX}, {TX} and {newlink} - backslashes needed because { } are special in regular expressions):

Code: [Select]
/etc/s6/config/connman.conf
===================
DIRECTIVES="n3 s2000000 T -\\{(RX|TX|newlink)\\}"

Read Logging Script Syntax on the official docos for more.


I'd try to investigate what's causing those issues, or at the very least try to make connman shut up, but couldn't find anything skimming the manual pages.

I don't use connman but the service script just simply runs it without forking. We don't even enable the debug option so in theory it's not supposed to be spamming. Something sounds weird if it's writing that much so quickly.

I guess OP's wireless network is somehow unstable failing and Connman is constantly disconnecting and reconnecting, given how many "newlinks" are generated every second.

Well, then I'll keep the log settings and investigate the underlying issue. Thanks for your replies so far!
