主题: Are Japanese characters allowed in hostname in /etc/exports?

Hello!

Can I use Japanese characters in the hostname for an export line in
/etc/exports? Or first convert hostname into a punycode string, and
then put that string into /etc/exports?

I did a simple test on my machine:

1) NFS server:
# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.122.16 アイウエオ

# cat /etc/exports
/nfsroot        アイウエオ(rw)


# exportfs -arv
exporting アイウエオ:/nfsroot


2) client:
# mount -t nfs -o vers=4.2 192.168.122.15:/nfsroot /mnt
192.168.122.15:/nfsroot on /mnt type nfs4 (rw,relatime,vers=4.2,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.122.16,local_lock=none,addr=192.168.122.15)

Looks like all good.

But as [1] mentioned...

The Internet standards (Request for Comments) for protocols specify that labels may contain only the ASCII letters a through z (in a case-insensitive manner), the digits 0 through 9, and the hyphen-minus character ('-').
