Re: [vchkpw] vpopmail vpasswd file difference(s) between 4.9.10 and 5.3.8 (convert from cdb to mysql)
Just in case anyone else runs into this, I wrote a little Perl script
that parses out /var/qmail/users/assign to fetch a list of domains that
are active on the mail server. Then, for each domain it goes out and
fetches the vpasswd file and feeds its contents into a SQL database. It
works quite nicely.

Re: [vchkpw] vpopmail vpasswd file difference(s) between 4.9.10 and 5.3.8
That was it, thanks HD. Upon comparing his vpasswd file and mine, there's an extra field in the vpasswd file for the clear text password. If I merely add another colon to the end of each line in the vpasswd file, vconvert works just fine. I'd suggest updating the vconvert program so that it does not require the clear text password field to be present in order to function properly. That will make legacy installs much easier to upgrade. Lastly, I'm not entirely certain *why* running vconvert against my older vpasswd file deleted all mysql entries in the vpopmail table but it's not a safe behavior. Maybe it just removes all entries that match the domain before importing and then does the import. It would be a really good idea to verify that there's some new data capable of being inserted before deleting the old entries. Matt On Wednesday, September 25, 2002, at 11:18 AM, H. D.

Yes, it actually works. Below are the steps I have taken to come up with that statement: 1. Compile and install 5.3.8 with cdb. 2. Test create a domain (devel.dutnux.com) and some users. 3. Recompile with mysql support, install, using 5.3.8. 4.

The vpopmail table contain exactly the user I created. > Can you sanitize a copy of a newer vpasswd file and send it my way so > I can compare it to my ancient system to see if the format is still > the same? This is the first line of the vpasswd file I have. It was created using 5.3.8 with password learning support: postmaster:$1$R.O7J$cRKPnHXAkWuZ6epI94R.k/:1:0:Postmaster: /home/vpopmail/domains/devel.dutnux.com/postmaster:10M:dutnux Sorry for the wrapped line. > Matt > HTH -- H.
