Enabling NFSv2 on Ubuntu 22.04
I had issues mounting an NFS export on a Ubuntu 22.04 server on some older OSes like HP-UX and Tru64. I had to enable NFSv2 to allow these systems to mount the NFS export.
In /etc/default/nfs-kernel-server, change RPCNFSDOPTS to include version 2, like this:
RPCNFSDOPTS="--nfs-version 2,3,4 --debug --syslog"Then, in
/etc/nfs.conf, in [nfsd], add vers2=yThen restart nfs:
sudo systemctl restart nfs-kernel-serverI have my directory exported like this:
/nfs 10.35.0.0/24(rw,no_root_squash,insecure)
