Hi All,

Please let me know how to implement if you have like solaris,linux,aix
servers

best practise like which o.s should i use a NIS master. I hope it
would not be better to have three different nis servers.

My objective of implementing nis is for centralized account
management.

Thanks,

Don't use LINUX for any of the server functions.  In many kernels, NFS
and NIS don't work except with other LINUX machines.

Have a master machine sitting in the datacenter that's backed up and
bottle fed regularly.  Many site's I've been at also have DNS on this
machine, but YMMV.

Have at least 1 NIS slave machine on each network segment or use a
multi-homed system across a couple network segments.  Some sites I've
been at have also used this as a file server.

Be careful of having lines in the groups map get to long.  I think 1024
is the longest.  

Think carefully about groups.  If you're going to use NFS, the maximum
number of groups a user can be in is something like 16 or 32 (I forget,
I'll let you research that).  If you need to use more than that you'll
have to use ACLs on machines that support that.

Use automounter for user and project directories.  If files are stored
on servers that are backed up, you won't be backing up desktops.  It
will save lots of network overhead.

Are you going to manage a hosts map or use DHCP?  I don't know what that
entails but be sure the ranges are mapped in local DNS.  Otherwise,
you'll have reverse lookup problems and slow remote logins.

Hi Michael,

Thanks for replying. So you are suggiesting either sun solaris or
IBMAix as a Nis Master and all the linux hostes to be nis clients

is above my understaing right?

Can you tell me how to connect Aix servers as NIS client to Solaris
nis servers.

Main purpose of implementing the NIS is i dont want the user to be
created on all the differnt version of unix. Create one id on NIS
master server and that user should able to login in all the servers.

Thanks
