Sun 17 Dec 2023 09:31:16 PM UTC, comment #2: I got an experimental branch with a fix freeipmi-1-6-0-stable-maxhostnamelen_increase git clone https://github.com/chu11/freeipmi-mirror.git git checkout freeipmi-1-6-0-stable-maxhostnamelen_increase ./autogen.sh ./configure make cd ipmi-sensors (or whatever tool you want to test with) ./ipmi-sensors -h REALLYLONGHOSTNAME ... PLMK if it works for you, thanks!	Albert Chu <chu11>
Sun 19 Nov 2023 08:30:23 PM UTC, comment #1: (sorry for late response, was on leave) Googling around, I guess the issue has been that gethostname() (on almost all systems) returns a max of 64 bytes (it's a linux kernel definition), so most people use MAXHOSTNAMELEN as their "max hostname" buffer size (which I did here). But technically, that need not be the case, as when you input a hostname on the command line, that's not related to gethostname() at all. I agree on a fix, but it will take a little time to peel MAXHOSTNAMELEN away and ensure things are portable (b/c MAXHOSTNAMELEN is defined in headers on most systems).	Albert Chu <chu11>
Fri 27 Oct 2023 07:54:13 AM UTC, original submission: Hello, We have a a problem when we use FreeIPMI, when we specified a hostname with more 64 characters, freeipmi can't collect data. We use FreeIPMI with ipmi-exporter project. https://github.com/prometheus-community/ipmi_exporter Can we grow to 126 the var MAXHOSTNAMELEN in code ? or add var to grow this params ? {"level":"error","msg":"Failed to collect ipmimonitoring data from host.name.example: exit status 1","source":"collector.go:376","time":"2020-08-18T13:11:02Z"}	jeremy planckeel <jplanckeel>
