Fedora Servers :: Migrate Local Users And Sendmail Mailboxes?

Apr 21, 2010

I found 2 previous posts, one from 2005 and one from 2006. The 2005 post was not very helpful and the 2006 threads are not exactly what I was expecting. So I wanted to ask the question to be sure. I have already stood up the new fedora 12 server. The old server is also fedora 12. I need to migrate local users and sendmail mailboxes. In the past couple of years the environment was small enough to create a copy of the users and then have the users mail themselves, but I want to start migrating users/mailboxes properly.

On a unix level I am a jr admin, but I have extensive senior level experience as a windows engineer and network engineer. I do feel comfortable with using the unix command line, but usually operate the unix systems thru webmin because I am not familular with more complex commands. Ideally a software solution to migrate users and/or mailboxes from one server to another is what I am looking for, but in leiu of a software solution I still need to migrate user accounts and their mailboxes. LDAP is not in place, but if the process becomes easier with LDAP I am willing to do what is needed to set up LDAP. (I have no previous experience setting up LDAP)

I do not want to change my mail server from sendmail to different software. At least right now. Both systems are up and running. They can connect to each other via public ipv4 address' only. The new server has already been installed and configured with all the software to match the old server. How do I migrate users and sendmail mailboxes from one fedora 12 server to another fedora 12 server?

Server :: Migrate Some Mailboxes Using Postfix?

Nov 8, 2010

I have postfix and mysql set up on one server running Ubuntu 6.10. I have to upgrade all them at their current versions and ensuring current email service on line. So, I installed in other machine the current versions of the same programs. The oldest server is the current MTA, the new machine is on line but I don't know where I should make changes that allow me move some mailboxes from one to other. I tried reassigning priorities in them MX's records but it didn't work.

Fedora Servers :: Sendmail Delivery To Local Boxes

Jun 1, 2009

I have fedora running as our email server at work using sendmail. It used to have spamassassin and MailScanner installed, but one of those died over the weekend and killed the mail server. We do not need either of these as we are using a web based spam filter now (postini), so I tried removing these. I have discovered that the mail is in the mqueue waiting for delivery to the users mailboxes. I have tried using "sendmail -q -v":

Running /var/spool/mqueue/n51Jx6Gg023820 (sequence 1 of 1174)
<abaughman@grandproductsinc.com>... Connecting to local...
<abaughman@grandproductsinc.com>... Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL

Running /var/spool/mqueue/n51JsuRe023619 (sequence 2 of 1174)
<ksullivan@grandproductsinc.com>... Connecting to local...
<ksullivan@grandproductsinc.com>... Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL .....

I do not have a procmail config file: /etc/procmailrc. I am not sure why, or what it should be, perhaps that is the problem. I guess I don't exactly know how this server runs all that well. I was able to get it up and running but never understood it enough to now find what is not working correctly.

Networking :: Sendmail - Change Domainname Local Users

Mar 26, 2010

I have the following problem and tried (almost) anything to fix it but without a full success.

We're running a server with CentOS 5.4. Every night a logwatch report is send. These mails are rejected by our mailserver because some invalid details. These mails are send to local user root which is redirected to another external mail address with /etc/aliases.

At first the mail was send from root@localhost.localdomain to root@localhost.localdomain. As you can imagine, our mailserver rejected this because the localhost.localdomain parts. So I changed the sendmail config with these options:

dnl EXPOSED_USER(`root')dnl

This solved my problem partially: Mail is now coming from root@domainA.com (which is OK), but is send to root@slave02.domainA.com (slave02 is the local hostname), which is not OK. I tried everything I could find to change that last part to, but nothing seems to work.

Ubuntu Servers :: Migrate Users To New Installation?

Jun 23, 2011

How do I migrate my user list to a new server installation? I thought that just copying /etc/passwd and /etc/shadow would be enough. I recently tried upgrading a lightweight bazaar server to 11.04, and the upgrade crashed. I had to perform a new installation of Ubuntu to recover operation of the system. I installed on a different hard drive. I had a dozen other people with user logins, so that they can get or modify bazaar repositories.

The new installation is running, and I can read all of the files on my old system's / drive. I tried copying the /etc/passwd and /etc/shadow files onto my new /etc -- but that did not seem to work. (When I looked using the System->Administration->Users-and-Groups GUI tool, there were no users visible, so I restored the old files.) What I intended to do was to clone the /etc and /home trees over to the new system. What am I missing?

Fedora Servers :: Migrate System To New Hardware?

Jul 11, 2009

I have a working system running some older fedora, and new hardware running a fresh, new fedora install. I want to basically transfer my computer's "soul" into the new system ( user's stuff, firewall configuration, the various server & security configurations, etc.) and basically any customizations and non-hardware related packages installed that weren't part of the standard fedora install process. I'm looking for a magical easy button I can push to do all this (pause for laughter). Essentially, I want to "upgrade", but starting with a clean install on a different computer with different hardware. I have a vague idea of what needs to happen, like copying the /etc/*.conf files, /home directory, etc. but this seems very tedious, and the likelihood of me forgetting or overlooking something is 100%, and copying over entire disks or partitions wholesale is not necessary, and does not work for this scenario. I need to place/merge just the right files/directories in just the right places with surgical precision. Is there a utility for this? Maybe a way to diff the packages of the 2 computers and install the difference? Or at the very least some sort of checklist that could be scripted for my system? I'm desperately trying to avoid the pain, human misery & suffering encountered getting everything in the 1st system going.

Debian Configuration :: Migrate The Users Without Resetting Their Passwords?

I have an old server running CentOS 5. The encription method used was the default MD5 for the shadow file. I would like to migrate the server to Debian Squeeze which uses SHA512.

Software :: Import Windows Users / Passwords Into Openldap Server - Ldap Migrate Migration?

Nov 18, 2009

I am looking for ideas for getting windows users into an ldap server. I am currently running a Linux server for my department and need to create an LDAP server which mirrors the username/password information for all of us as they are stored in the windows server here. I have the openldap server up and running on Ubuntu 8.04 and it works great; I now need to find some way to import user info into this from windows. I've seen discussions of using ldifde.exe to export the AD users into an ldif file. Is this the simplest way to go about it?

Our Linux server is currently providing us with much needed services using apache, and apache is authenticating using LDAP to our windows server (Using our windows username / password is required functionality). This windows server has some problem which causes it to delay for inordinate amounts of time between authentication requests and responses. The situation is such that this problem will not be addressed by IT staff. However, I have control over the Linux server so I am looking to just mirror the windows server on an LDAP server of my own. I could get away with updating the passwords in the Linux server.

Never had to do this before, but I had not updated sendmail in a while. Just a heads up in case anyone else is about to perform updates.

Fedora Servers :: Sendmail And Home Network Woes?

Feb 22, 2011

I have a rather interesting issue. I have set up a home network and a fedora 14 box as a server. I am running the version of Sendmail that came with fedora 14. I wrote a PHP script that changes http access passwords(to give authorized access to the outside by multiple users) once a week and emails the users their new passwords. It also finds out my WAN IP (because it is dynamic, and I am using a Linksys router with NAT), and E-Mails users when this has changed along with the new access password. I have Sendmail set up so that it should log on to my websites mail server (smtp.example.net) and send the email through it.

The problem I am having is that I have set up my home server with an internal domain like exampledomain.home, but the wan IP reverse lookup returns xx.xxx.xxx.xxx.static.xxx.xx.charter.com, so that when my sendmail server connects to my smtp server for my website it gives "EHLO server.exampledomain.home" then my smtp server rejects it because the connecting IP (WAN IP) resolves toxxx.xxx.xxx.xxx.static.opls.la.charter.com gives a host not found error. Or it gives the error because server.exampledomain.home is obviously not a valid host name on the internet. I was hoping someone out there had some insight on how I could get around this without editing or adding any DNS entries to my websites domain. I would also like to avoid getting a static IP for my house as it is more expensive. I thought about making a dynamic DNS entry with dyndns.com and then making Sendmail use that host name. I dont know how to trick sendmail like that though.Here is a copy of my sendmail.mc (scrubbed of course).

General :: Sendmail Not Authenticating Users?

Jan 24, 2011

Can connect to our mail server using telnet onto port 25 and this works correctly, 'ehlo whatever' shows output as expected.

However using a mail client to connect it gives an authentication error and the following appears in the maillog file;

did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

what to look for in the config, this works correctly on our development box but not on our production server. Could it be another program is interfering with the connection?

Sendmail is running in standalone mode not through the xinetd daemon.

I am using the PLAIN AUTH method as to try and avoid getting more errors.
