Description

Forum user got a SNMPv3 set problem when set SNMPv3 related entries.

I got perl locale warning and the set failed.

curl --request POST ‘http://localhost/configure’ --form data=‘{“op”: “set”, “path”: [“service”, “snmp”,“v3”,“user”,“user2”,“group”,“default”]}’ --form key=‘webkey’

And got error as follow:

{“success”: false, “error”: “perl: warning: Setting locale failed.\nperl: warning: Please check that your locale settings:\n\tLANGUAGE = (unset),\n\tLC_ALL = (unset),\n\tLC_CTYPE = "C.UTF-8",\n\tLANG = "en_US.UTF-8"\n are supported and installed on your system.\nperl: warning: Falling back to the standard locale ("C").\n[[service snmp]] failed\nCommit failed\n”, “data”: null}

It is no problem by using configure CLI. There is no problem to set any SNMPv2 date by HTTP API.

Most likely this is realted to https://github.com/vyos/vyos-1x/commit/7e0e8101998a6c8de6cb93c42bfbf1278c13f226

I am not yet able to reproduce this in either case. @c-po suggestion of an interaction with the introduction of vyos.utils.configfs is quite reasonable, but I have not reproduced in current rolling or an image earlier than the recent changes (T6633, T6640) to resolve T6639. I've asked the forum user of the second report for further information.

I believe I am bumping into this issue aswell:

$ curl -k --request POST 'https://localhost:8443/configure' --form data='{ "op": "set", "path": [ "service", "ntp", "server", "time1.vyos.net", "prefer" ] }' --form key='MySuperSecretKey'
{"success": true, "data": "perl: warning: Setting locale failed.\nperl: warning: Please check that your locale settings:\n\tLANGUAGE = (unset),\n\tLC_ALL = (unset),\n\tLC_CTYPE = \"C.UTF-8\",\n\tLANG = \"en_US.UTF-8\"\n    are supported and installed on your system.\nperl: warning: Falling back to the standard locale (\"C\").\n", "error": null}

The error itself seems to come from the commit post hook:

$ until pgrep -fal perl; do :; done;
22246 /usr/bin/perl /etc/commit/post-hooks.d/10vyatta-log-commit.pl

Which is triggered by my-commit but ultimately I think the issue is that the http server does not have the locale settings configured fully as the error mention:

$ xargs --null --max-args=1 echo < <(sudo cat /proc/$(pgrep -f vyos-http-api-server)/environ)
LANG=en_US.UTF-8

I can recrete the issue in a container using the latest (1.5-rolling-202411030007) iso, I created a little Makefile and vbash script that reproduces the issue on my system, in the hopes it can help.
FYI: It will require docker (or podman), xorriso, squashfs tools and jq to be available.
