AMD Automounting

This works on both FreeBSD and DragonFly BSD. It should work on any OS that uses the BSD amd daemon.

See http://docs.freebsd.org/info/amdref/amdref.info.Home_Directories.html

Server Configuration

The host is running FreeBSD -current 7.x

• /etc/exports

[faith] ~> cat /etc/exports
/usr -alldirs -maproot=root -network 192.168.45.0 -mask 255.255.255.0

• showmount -e

[faith] ~> showmount -e
Exports list on localhost:
/usr                               192.168.45.0 

Client Confguration

The client is DragonFly BSD -current running as a guest OS under Qemu. Networking is enabled using the tun/tap interface.

• rc.conf.local

[faith-df] ~> grep amd /etc/rc.conf 
amd_enable="YES"
amd_flags="-l syslog /homes /etc/amd.homes -cache:=inc /net /etc/amd.net -cache:=inc"

• amd.homes

[faith-df] ~> cat /etc/amd.homes 
/defaults       type:=link   # All the entries are of type:=link
shanu           fs:=/net/faith/shanu

• amd.net

[faith-df] ~> cat /etc/amd.net 
/defaults       opts:=rw,intr,nodev,grpid,suid,nfsv3,tcp
faith           host!=faith;type:=nfs;rhost:=faith;rfs:=/usr/home

Update $HOME

Update $HOME to point to /homes/shanu on hosts where automounting is setup.

[faith-df] ~> sudo pw usermod shanu -d /homes/shanu
[faith-df] ~> finger shanu
Login: shanu                            Name: Shanker Balan
Directory: /homes/shanu                 Shell: /bin/tcsh

• ssh to the box

[faith] ~> ssh qemu-df
shanu@qemu-df.shanu.net's password:
