how many types of user accounts are available in linux os? if i assign a uid below 500 to a norma..

Answer / prajakta aher

There are 3 types of user accounts in linux.They are:
1> System Users
2> Root User(Administrator)
3> Other Users(Normal User)

In linux, Uid from 1 to 500 has been reserved for system
users,these are the default users of linux,so if anyone try
to assign Uid 500 to normal user then it wil give the error.

Answer / rallapalli

1.root user (admin --- 0)
2.System users ( 1 to 499 )
3.Normal users ( from 500 )

when u want to assign below 500 id first check in
/etc/passwd file which id is free ( not assigned to any
user) u can use that id and u can assign. Assume 356 id is free
EX: #useradd -u 356 tom
system will give u error but the user has created
successfully. Now check the /etc/passwd file u will get tom
user entry with uid 356 ok?

Thanks

Answer / susheel narayan singh

There are three type of user accounts-
1- Super user (root) uid and gid =0
2- System user (ftpd,sshd) uid and gid (1-499)
3- Regular user (what u create with useradd cmd) uid and
gid (500<)

Note: If you assign uid below to 500 like between 1 to 100
it means that user umask will be 022 like root.
And you know that normally user whose uid and gid is above
their umask is 002.

Answer / ajay

root 0
system user 1 to 499
normal user 500 to 60,000

so if you try to give uid <500 for normal user then it will give an error.
