Membuat user hanya "ftp" di solaris

1. Create user
# useradd -d /export/home/userftp -g staff -c "Ftp user only" -m -s /bin/false userftp

2. Cek user yang dibuat
# more /etc/passwd
userftp:x:502:10:Ftp user only:/export/home/userftp:/bin/false

3. Create password userftp
# passwd userftp
New Password:
Re-enter new Password:
passwd: password successfully changed for userftp

4. Create file /etc/shells, secara default file ini belum ada dalam system
  a) Jika sudah ada, edit file,
     # vi /etc/shells
     --dan tambahkan:
     /bin/false

   b) Kalau belum ada lakukan terlebih dahulu

      ls /bin/*sh > /etc/shells
      kemudian lakukan langkah 4.a

# more /etc/shells
/bin/bash
/bin/tcsh
/bin/zsh
/bin/false

5. Sekarang test fungsi login userftp tanpa memiliki akses telnet and ssh.

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
19:03:47:d6:51:4a:55:3e:af:64:fb:18:9e:40:ce:37.
Please contact your system administrator.
Add correct host key in /.ssh/known_hosts to get rid of this message.
Offending key in /.ssh/known_hosts:2

RSA host key for localhost has changed and you have requested strict checking.
Host key verification failed.

SEMOGA BERHASIL!!!
