Using AWK to convert UNIX passwords from HP-UX to Solaris

Converting password hashes from HP-UX 11.11 to Solaris is pretty simple if you are using UNIX crypt passwords (if HP-UX isn't a Trusted System. If it is, it will use bigcrypt passwords, > 8 characters, converting them to Solaris UNIX crypt could be problematic).

Here's the gest of it:

On the HP-UX System, we create a test user:

# useradd test
# passwd test
test
Now we convert the passwd file to generate passwd entries for Solaris:

  • # awk ' BEGIN { FS = ":" } { print $1":x:" $3 ":" $4 "::/export/home/" $1 ":/usr/bin/sh" }' /etc/passwd
  • test:x:107:20::/export/home/test:/usr/bin/sh

And we create the shadow file entries, including the password hash:

  • # awk ' BEGIN { FS = ":" } { print $1":"$2"::::::" }' /etc/passwd
  • test:lsDWJo7M.iAhY::::::
Just add them using /usr/ucb/vipw to the password file, edit the shadow file for consistency and test. Be sure to backup the files and to test using a few users at first.

  • $ su test
  • Password:
  • $ id
  • uid=127(test) gid=120
  • $ whoami
  • test
  • $ echo $HOME
  • /export/home/test
  • $ echo $SHELL
  • /usr/bin/sh
Mix with some shell scripting and mkdir's and you're set :-). Next time, use LDAP :P.
