RE: [vchkpw] Re: Best Way To Import cdb to MySQL w/ Alterations
Peter, As I suspected vconvert doesn't lookup the location of vpasswd based on assign or any other file for that matter. It only seems to use the vpopmail home directory. Here is the strace segment that tells the story. 2140 read(3, \377\32\4Table \'vpopmail\' already exists, 34) = 34 2140 open(/sites/home/vpopmail/postoffice/hcx.net/vpasswd, O_RDONLY) = -1 ENOENT (No such file or directory) 2140 write(1, converting hcx.net domain conversion failed\n, 44) = 44 2140 exit(0) = ? Of course vpasswd isn't located at /sites/home/vpopmail/ on my new systems. It is under the users directory. If vconvert had a -u switch which we could use to designate the user and thus the users home directory I think vconvert would work great. However it doesn't. If there was a -u switch it could default to ~vpopmail thus keeping to typical configuration. Anybody up for a patch?

RE: [vchkpw] Re: Best Way To Import cdb to MySQL w/ Alterations
Peter, I know nothing of strace(). The conversion seems to want to find it at the old path of ~vpopmail/domains/someonesdomain.com/ and it gladly converts if it finds the information there. But of course all of the paths are wrong Since you obviously know the 'big picture' better than I do maybe you can tell me if this will work. What if I recreate the postmaster account, move the user directories (besides postmaster) and then import user records into the mysql.vpopmail.vpopmail table. Will that work? Is it missing anything? I figure the recreation of postmaster will create the necessary control and assign files and the copy and import into mysql will handle the individual users under the domain. What do you think? What vpopmail needs is a big picture like Dan has put together for qmail. I think that would be a very valuable resource. Have one that shows the schematic of qmail/vpopmail using .cdb and then one showing qmail/vpopmail using mysql. That would be most informative.

RE: [vchkpw] Re: Best Way To Import cdb to MySQL w/ Alterations
Peter, cp -R /sites/home/vpopmail/domains/someonesdomain.com/* /sites/http/somonesdomain.com/postoffice/someonesdomain.com/ vconvert -c -m someonesdomain.com Only results in converting someonesdomain.com domain conversion failed Is there something I have to do before hand that I am not aware of? I can add new domains and they all go where they are supposed to go adding the correct information to /var/qmail/users /var/qmail/control and vpopmail.* but once I get to conversion nothing! And this is a machine with 1 virtual domain. I am already having nightmares about getting to the machine with 250 domains.
