Re: Debian 12 kernel NFS server doesn't listen on port 2049 UDP

	Hello,

after upgrading one of my systems from Debian 11 to 12 the kernel NFS server
doesn't seem to accept NFS requests over UDP on port 2049 anymore:

	>rpcinfo -p | grep nfs
	    100003    3   tcp   2049  nfs
	    100003    4   tcp   2049  nfs
	    100227    3   tcp   2049  nfs_acl

This causes problems for a non-Linux NFS client whose automounter
tries to perform the mount over UDP. Is there a way to re-enable
the UDP port?

	Kind regards



Edit /etc/nfs.conf file:
[nfsd]
udp=y

then:
sudo systemctl restart nfs-server

Result:
$ rpcinfo -p | grep nfs
    100003    3   tcp   2049  nfs
    100003    4   tcp   2049  nfs
    100227    3   tcp   2049  nfs_acl
    100003    3   udp   2049  nfs
    100227    3   udp   2049  nfs_acl
