[vchkpw] [Fwd: [qmr] vpopmail with LDAP]
Hi, I'm trying to change vpopmail (currently with mysql backend) with LDAP support. vpopmail do all the authentication works for email transaction. Vpopmail version 5.4.9. Openldap 2.3.4 with sasl OS : FreeBSD 4.10 untar-ed the source and edited the vldap.h file. then : ./configure --enable-auth-module=ldap completed without problem. when "make", i got these warnings and errors : vauth.c: In function `vauth_getpw': vauth.c:119: warning: implicit declaration of function `ldap_search_s' vauth.c:126: warning: implicit declaration of function `ldap_perror' vauth.c:153: warning: implicit declaration of function `ldap_get_values' vauth.c:153: warning: assignment makes pointer from integer without a cast vauth.c:186: warning: implicit declaration of function `ldap_value_free' vauth.c:229: warning: assignment makes pointer from integer without a cast vauth.c:242: warning: assignment makes pointer from integer without a cast vauth.c:259: warning: assignment makes pointer from integer without a cast vauth.c:271: warning: assignment makes pointer from integer without a cast vauth.c:283: warning: assignment makes pointer from integer without a cast vauth.c:292: warning: assignment makes pointer from integer without a cast vauth.c:301: warning: assignment makes pointer from integer without a cast vauth.c: In function `vauth_getall': vauth.c:373: warning: implicit declaration of function `ldap_sort_entries' vauth.c:388: warning: assignment makes pointer from integer without a cast vauth.c:410: warning: assignment makes pointer from integer without a cast vauth.c: In function `vauth_adduser': vauth.c:578: warning: implicit declaration of function `ldap_add_s' vauth.c: In function `vauth_deldomain': vauth.c:708: warning: implicit declaration of function `ldap_delete_s' vauth.c: In function `vauth_setpw': vauth.c:891: warning: implicit declaration of function `ldap_modify_s' vauth.c: In function `vclose': vauth.c:914: warning: implicit declaration of function `ldap_unbind_s' vauth.c: In function `ldap_connect': vauth.c:1339: warning: implicit declaration of function `ldap_init' vauth.c:1339: warning: assignment makes pointer from integer without a cast vauth.c:1349: warning: implicit declaration of function `ldap_simple_bind_s' gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'file_lock.c' || echo './'`file_lock.c gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'vpalias.c' || echo './'`vpalias.c gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'seek.c' || echo './'`seek.c gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'vlimits.c' || echo './'`vlimits.c gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'maildirquota.c' || echo './'`maildirquota.c rm -f libvpopmail.a ar cru libvpopmail.a vpopmail.o md5.o bigdir.o vauth.o file_lock.o vpalias.o seek.o vlimits.o maildirquota.o cdb/*.o ranlib libvpopmail.a gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'vchkpw.c' || echo './'`vchkpw.c gcc -I. -I/usr/local/include -I. -I. -I. -g -O2 -Wall -c `test -f 'hmac_md5.c' || echo './'`hmac_md5.c gcc -g -O2 -Wall -o vchkpw vchkpw.o md5.o hmac_md5.o libvpopmail.a -L/usr/local/lib -lldap -llber -lresolv -lcrypt /usr/libexec/elf/ld: cannot find -lresolv what is this lresolv?

[vchkpw] Migrating users
I've recently gone through a server migration of 20 or so domains, none of which had a ton of email in them. Here's what I did: 1. add domain to new server using vadddomain 2. stop qmail-send on old server 3. tar/gzip /home/vpopmail/domains/domaintomove.com directory 4. Move to new server and untar into place, overwriting existing vpasswd and postmaster files. 5. vdeldomain on the old server 6. add domain to rcpthosts on old server 7. add domain:newserver to smtproutes on old server 8. restart qmail-send 9. change DNS. This worked fine for my small server with few messages and few clients that would notice anything strange. However, I've been asked to do the same on another mail server with several hundred domains and 15 gig of mail. In order to transfer one domain with lots of mail, I could potentially have to have the stuff down for an extended period of time. I don't want people reading email while I'm tarring up their domain's email. My question is... is there a better way than the steps I described above? Rick

Hi, I do exactly the same but I rsync instead of tar and try to do the rsync before shutting down the old servers qmail-smtpd/send, then the final rsync is quite quick. Regards, Rick

You can run it once while everything is live, then stop qmail and run it again to sync up anything that changed since the first run. Very slick. I wrote some scripts to aid in migrating to a new server, and Paul Kremer recently prettied them up. Give them a shot, they should make the migration go fairly smoothly. They automate the procedure, and even include the multiple calls to rsync, along with vadddomain on the new server, etc. http://www.mail-archive.com/vchkpw@inter7.com/msg22410.html I recommend adding a dummy domain on your old server and use it as a dry run for the migration scripts. -- Tom Collins - [EMAIL PROTECTED] QmailAdmin: http://qmailadmin.sf.net/ Vpopmail: http://vpopmail.sf.net/ You don't need a laptop to troubleshoot high-speed Internet: sniffter.com
[vchkpw] Courier-imap+vpopmail problems
Hi guys!!! I´m new in this list and had subscribed here for some help. Yes, i read all msg of this list about my thougth. I have a Linux box Fedora core 3, mounted with Qmailrocks "cake guide" with vpopmail 5.4.9, qmailadmin 1.2.3, courier-authlib-0.57, courier-imap-4.0.6, squirrelmail-1.4.5, this configuration works well, but every day I had to reboot the machine because sundely the authentication stops, and nothing i do for restart the processes to recover this thing is valid. Simplily the authentications stop, and only rebooting the machine i get to recover the things to normal. No logging messages are register for this. Somebody had this problem too? Know the solution for this? Please excuse me my poor english, and i hope my problem is clear. thanks in advance. cmattos_58
[vchkpw] Migration using Rsync - Memory Problem
Hello List. I'm worried because my migration scheme is giving problems. My migration plan was use rsync for transfer all user's mailbox, but it don't work because my directory tree is very big. I have around 50K maildir directory (110 GB approx). I checked the rsync documentation and I note that it have memory problems with big directory tree (It use a lot of memory and it does shutdown my server). I need transfer all the maildirs without turn off the mail service or in any case, the time off of service should be short, for that reason I did think use rsync, because it could make incremental copy. Please, somebody know others alternative to rsync? Bye

Hi, Use rsync but with a script file that limits the number of files it does per pass. ie rsync vpopmail/domain.com/0 remote.example.com::vpopmail/domain.com/0 . . . rsync vpopmail/domain.com/Z remote.example.com::vpopmail/domain.com/Z Regards, Rick

Tom. But the rsync have problem when the directory tree is very big. What alternative could use against of rsync... Another technique for sync files?

I couldn't possibly imagine migrating a large qmail/vpopmail system with something lesser than rsync. rsync on BSDi and perhaps other BSD systems do have this problem. I've run into it before. I've never had that problem with a Linux system though. Guess I might if I had less than 512 meg of ram or so though. It's not the size of the files, it is the number of files. Rick
