As always, hastily written, pwd_migrate cobbles together some shell commands to create new VPS v2 users from a VPS 1-style passwd file. Current version: 1.8 2004/12/08 21:17:57

Notes

    ./pwd_migrate passwd

(pwd_migrate needs to be executable by root, so chmod u+x pwd_migrate after you download it)

The following things will happen:

• for each line in the passwd file, a new account will be created UNLESS the account name already exists. It will tell you it is skipping that account as it goes through the file.
• the new account will have the same services (e.g., ftp, mail) as the old vps1 account. If the account had only mail services before, it will have only mail services on the vps2.
• the new account will have a quota that is the sum of the former vps 1 per-service quotas. For example, if the old vps1 account had a 10 meg mail quota and a 10 meg ftp quota, the new vps2 quota will be 20 megs.
• the original password hash is preserved for the new account.

Note that the old-style DES password encryption is much weaker than the VPS v2 MD5 encryption. This is mitigated somewhat by the actual /etc/master.passwd file being much more restricted than the old VPS 1 file was, however. If you're paranoid about security, you can ask your users to change their password. If you know the password as the administrator, you can reencrypt it with the passwd command.

This program was written using the principles and programs described on the VPS v2 managing_users(5) manpage.

To do:

• fetch the old VPS 1 home directory contents and save them in the new home directory

usage: 

pwd_migrate [-d] passwd_file

examples:

1)  pwd_migrate passwd.old

will create accounts for all entries in passwd.old (except 'root' and
'ftp').

The -d option enables debugging and will NOT take any actions--only
show you what it would do.
