Exceeded maximum length of socket pathname

[Tom-python0121]

when i use:munge -n, some error happend.

Steps to reproduce the issue

[root@localhost sbin]# ./munged -S ../var/run/munge/munge.socket.2
[root@localhost sbin]# munge -n
-bash: munge: command not found
[root@localhost sbin]# cd ..
[root@localhost munge-0.5.14-226zewtxozsftf3gjc6ttnwskq4msqkj]# ls
bin  etc  include  lib  sbin  share  var
[root@localhost munge-0.5.14-226zewtxozsftf3gjc6ttnwskq4msqkj]# spack load munge
[root@localhost munge-0.5.14-226zewtxozsftf3gjc6ttnwskq4msqkj]# munge -n
munge: Error: Exceeded maximum length of socket pathname

Why would it happen?

Communication with munged is over a UNIX domain socket. The name of this socket must fit within a 108-byte static array in struct sockaddr_un.

The default name for this socket is ${runstatedir}/munge/munge.socket.2. It can be overridden at buildtime with configure --with-munge-socket=PATH. It can also be overridden at runtime with munged --socket=PATH (for the server) and munge --socket=PATH (for the client). But the length of the socket pathname must be less than 108 bytes.

@dun Is that what you mean?
[root@localhost sbin]# ./munged --socket=../var/run/munge/munge.socket.2
[root@localhost sbin]# munge --socket=../var/run/munge/munge.socket.2

Why is it stuck here?It's not going down. It's stuck here.

The munge -n command-line arg has nothing to do with the Error: Exceeded maximum length of socket pathname. You're getting that error because the software was configured with a socket name that exceeds the 108-byte static array. You can see the default socket name shown in brackets with: ./munged -h | grep socket=

If you don't specify -n to munge --socket=../var/run/munge/munge.socket.2, the munge client will read from stdin until it gets an EOF -- it's not stuck. Try entering ctrl-d, or add -n to the munge command.
