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.

It's running vpopmail 4.9.10 using cdb authentication. I'm upgrading

I've build out the new 5.3.8 system and cluster of machines. It's all
up, running and happy. I've NFS mounted all the home directories from
the old cluster onto the new system so that I have ready access to the
vpasswd and vpasswd.cdb files. They are mounted onto the local
filesystem so that the paths in /var/qmail/users/assign are correct.
I run vconvert -c -m test.domain.com and it exits quietly indicating
success:
mail8# ~vpopmail/bin/vconvert -c -m -v -d test.simerson.net
version: 5.3.8
converting test.simerson.net done
However, when I check the MySQL server, there's no entries in the
vpopmail table that correspond to that domain. :-(
I've tested this one step further. I've manually added a valid user
([EMAIL PROTECTED]) into the new mail system by manually adding
it into the MySQL table. It works fine, authenticates, etc. That
basically makes it work with my new mail system and the old one at the
same time. Cool. Anyway, if I run vconvert again, it'll actually
delete that entry from the vpopmail table. Is that supposed to happen?
Everything on the new system works just fine except the vconvert
function. Can anyone verify that vconvert actually does work? 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?

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.
