Server :: Dovecot-lda/postfix - Failed: Permission Denied
Apr 27, 2011
I'm sooo exausted after two days of fooling with this. The problem: Apr 27 17:29:21 mxkasib dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=8(mail) egid=12(mail) missing +w perm: /var/run/dovecot/auth-userdb, euid is not dir owner)
Obviously, dovecot-lda, instanced by postfix, couldn't access the auth-userdb file because of permission. There are plenty of topics over the internet, the problem is really simple. Except for I've got all the permissions needed, or it seems to me so and I'm missing something. Here is some additional information:
[Code]...
I've given all the permissions I could imagine. It's even devil 666, and it still complains.

I have a Ubuntu box and just got a new hard drive. Rather than copy everything over from my old working Ubuntu install, I wanted to install Ubuntu from scratch and then rebuild the file contents.I have a large collection of music that I use on my mac (another computer) and like to keep sync'ed to the Ubuntu box. The following script used to work flawlessly:
Im a fairly new linux person and have a hopefully easy question. I am running centos with dovecot and postfix for the mail. Im using imap so all the mail is on the server. Im also using thawte certificates. What is the easiest way to move all of this over to a more stable box? The box i have now is a major POS.
CentOS 5 box was just setup to replace a crashed old one. I have postfix.admin installed and working, added users (confirmed from mysql command line) and can login using telnet server pop3 with the user information. The problem I am left with is just receiving mail. I have both squirrelmail and roundcube installed, and can also authenticate using both (/var/log/maillog shows);From either webclient I can naturally send mail out and both yahoo and gmail client confirms, yet a reply shows nothing, and nothing ever shows in the maillog. Firewall is shut down but I don't know postfix enough to see how to test, or is something else grabbing the mail.
I can provide anything necessary, just let me know what. As I see it (just so far) Postfix should be the server that answers and receives the mail, dovecot is more the pop/imap the client would use, so I think it's a postfix issue. If so, can I turn up the debugging, etc. but again, I think all mail received should appear in the maillog file 1st as I see the outbound mail go fine!
I cant install Ubuntu 11.04 , on my Emachines laptop. On my Windows 7, When I boot up my USB/CD/card, it says: Ubuntu failed to mount dev/loop0 , something like that everytime, no matter what I do. And when I try wubi it says permission denied, .log filed saved. I've also mounted it using clonedrive, nothing works.
I have my DNS configure in 2 zones. 1 internal, and the other external. DNS is chrooted under /var/named/chroot amd has been operating without any problems for well over 2 years now. I have recently run cross the problem shown in the subject line. When I try to freeze the internal dehnert.com zone with the following command...rndc freeze dehnert.com IN internal
I get the error...
I have been running the command as root, and with iptables turned off, so there is no firewall to restricting access. (the system sits behind a firewall) I have been searching the forums all over, but I havent run across what might be causing me to have root denied access. If anyone has seen any problem like this, please point me in the right direction so I can iron this out.
I am running CentOS 5.2 on a server here in my home. It runs Dovecot and Postfix and also serves as a website host for a small website of mine. Everything works fine. POP, SMTP, Webmail, WWW, all works great and has for ages.Here's the issue. I recently reinstalled a clean copy of Windows 7 on a workstation in my home onto a new harddrive(I still have the old drive int he machine so I can boot to it as well). I setup the Windows Live Mail client to send/receive mail with my mail/web server. However, it won't connect to the POP server on my server machine.Here's the kicker. If I boot to the old harddrive that is running Windows 7, it connects fine to my mailserver and can send/receive just fine. I've checked, rechecked and rechecked and all mail settings on the mail clients on both drives are identical.
Note: The installations of Windows 7 on both drives is identical. Same computer name/ same credentials, same IP, etc. However, as I stated, I can send/receive email with my server if I boot to my old drive, but if I boot to my new drive, I cannot send/receive.
I did a a basic install of postfix and dovecot instead of using courier-pop and courier-imap. This is only send and receiving e-mail locally within the test network 10.7.0.X and 10.0.0.X. I used:
[URL]
my postfix.conf is;
PHP Code:
[code]....
This is the error when I send an email from a local machine on the 10.0.0.X network.
PHP Code:
Jan 20 17:05:48 testbox postfix/smtpd[2491]: warning: Illegal address syntax from unknown[10.0.0.111] in MAIL command: <test@10.0.0.112>
I am running Fedora 10, Postfix and Dovecot I recently changed the password of a user using the 'passwd' command. The problem is that the user can no longer receive their email messages in Thunderbird (Authentication Error). However, they can still login using SquirrelMail and get their mail.
We are planning on rolling out a mail service that will backend a webmail/groupware interface using postfix and dovecot, and we are trying to nail down an architecture for the system. I was hoping I could get some opinions from you good people on the different models we have come up with, and any improvements. To preface this discussion, we use NFS as the backend storage for mail so that clusters of mail servers can be created.
One possible solution is to separate three services, inbound email, outbound email, and message retrieval onto separate servers. We currently run a mail system with 65K users in this manner and it works, but there is a lot of wasted cpu on the inbound and outbound mail servers. where the dovecot servers are doing most of the work.
Another solution would be to combine the dovecot and inbound postfix servers to run dovecot as the local transport agent for postfix with LMTP, giving us quota and sieve capability.
The last solution is to run all three services on the same machine, giving us a single server image that we can clone on demand when we need to add more performance.
The single server, all three services, solution seems to be the simplest to build and manage, but putting all your eggs in one basket like that concerns us. What if there is a sudden influx of mail from our filtering platform, and it slows down all the other processes? What if the NFS server becomes disconnected from the network and the load average on each server skyrockets killing the ability for outbound mail to flow (where a separate outbound mail server would continue running despite this issue)?
I have a Postfix+Dovecot and virtual users setup taken from here. I've got virtual users authenticating using a password file. But I'd like to lock the service down further, so authenticated users can only email other authenticated users (those listed in the same password file) - so it's a closed community. I don't seem to be able to stop authenticated users mailing outside the community.
When I send an email via TLS I see the following log entries.
Code: Oct 14 11:53:06 ns2 postfix/smtpd[11372]: connect from unknown[172.16.1.159] Oct 14 11:53:06 ns2 postfix/smtpd[11372]: setting up TLS connection from unknown[172.16.1.159] [Code]....
What I'm really curious about is there is an intial TLS connection with a 256 bit cipher, but then.. The last entry states "sasl_method=PLAIN" - so surely this is not encrypted? Or am I misunderstanding how it works?
I tried a 9.10 -> 10.04 upgrade that went fail. I can now get it to the login screen where it gives a hard freeze. Same with recovery. I can get to a command line, but not with networking so
So I finally said screw it, I'm going to doa fresh install. I downloaded and burned 10.04 at work. Not, it is giving me an installer error when I boot from it, but then it will load the desktop from the LiveCD.
All I really want to do is grab some data that I didn't get when I backed up by home directory, then I can go back and do a fresh install. I can even download a new 10.04 CD if I need to because the installation files are screwed up or something.
The problem is that some of the files have permissions on that that show as an 'X' on the icon and it won't let me copy them to my USB backup drive.
How can I copy the files marked with an 'X' that have this permission issue?
I'm trying to add a key public key for my dev box which is a vm running ubuntu natty, and I am unable to connect via ssh. I've tried rsa and dsa, as well as these commands:
I had debian lenny running smoothly for a while, then I think the power went out and the computer didn't shutdown smoothly. The next time I started it up I ran into this error: Checking root file system.../etc/rcS.d/S10checkroot.sh: line 274: /sbin/logsave: Permission deniedfailed (code 126)This happens in single user mode as well. I've tried fscking all my partitions but it doesn't help. I've booted in bypassing the normal init and changed the permissions of /sbin/logsave to 777 and during boot I get a message of: The file system check corrected errors on the root partition but requested that the system be restarted. failed!Then the system just reboots automatically without letting me to anything.
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only.I had follow this how-to http://www.linuxmail.info/squirrelma...o-in-centos-5/ and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works.I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, i install VM player on it and run CentOS inside the VM Player.I want to do testing on Windows 7 side by installing Thunderbird email client program, i want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How ?
Do i have to do any other configuration on CentOS ? any DNS ? port number for IMAP,POP3 or SMTP ?
I have a problem concerning the vacation(auto response). I got a mailserver(smtp.mydomain.com), pop3/imap-server(mail.mydomain.com) webserver(www.mydomain.com, with postfixadmin on it). I use Debian 5.0 So it's like this, I receive mail to smtp.mydomain.com, it get checked for spam with amavisd-maia(Maia Mailguard), then delivered to the pop3/imap-server. I'm guessing there's something wrong with my postfix setup. I activate auto response for my account, when I get a mail it says this at smtp.mydomain.com:
I just isntalled LAMP using tasksel and have a problem. Whenever I try to access a page (aside from phpmyadmin, that works well), I get this error... Code: Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0 Fatal error: Unknown: Failed opening required '/var/www/index.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0
I have restarted the computer, restarted apache, etc and still nothing. When I first installed, phpmyadmin was inaccessible, so I ran some command in terminal which apparently created a symlink between phpmyadmin in the user/share dir to the /var/www dir, and curious if this is the problem. I have no clue how to remove this symlink if this is the case, and have phpmyadmin working now due to install using sudo apt-get install phpmyadmin.
I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.
However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.
the mail server itself will receive mail, that part works. i'm using dovecot imap to grab my mail, that works. but if i try to send mail from my iphone using an account on that server it doesnt work. this is what i see in syslog: May 15 07:14:52 coax postfix/smtpd[1432]: NOQUEUE: reject: RCPT from mobile-166-137-139-003.mycingular.net[166.137.139.3]: 450 4.1.8 <eppo@customconnexions.com>: Sender address rejected: Domain not found; from=<eppo@customconnexions.com> to=<xxxxxxx@aol.com> proto=ESMTP helo=<[10.25.15.47]>
Few days ago we had a server maintenance. The system was shutdown, we fix the CPU fan, and start the system again. But somehow when the system starts, our IMAP server - dovecot is not running. It just sit like a rock. Because the machine had a CPanel/WHM, I tried to restart dovecot using cpanel and got a message:
Code:
That was not really useful....
When I tried to restart dovecot using command line, I got nothing. really nothing.
Code:
How to find out what happens to my IMAP/dovecot? And anyway to make it run again?
I have a user (let's call him John) who is not able to list contents of several 777 directories even though it appears he has permission to.
Case in point, as root:
Code:
Code:
If I use ls -a or strictly ls as john, I can list the contents of the nss directory:
Code:
That says to me that I have an issue listing permissions. Fine, I don't really need john to be able to list permissions. I want him to have rwx access to /media/nss/ENG which as you can see from my listing as root shouldn't be a problem since the perms on that dir are 777.
I am able to CD into the ENG directory or any other directory or subdirectory in /media/nss that has equivalent 777 perms, but once in the directories I can't list the contents:
Code:
I can get anywhere and do anything I want under the media/nss folder as john, except listing files. I even tried using an ACL i.e.
I am trying to give an SSH user on my server permission to compile C exploit with gcc, and I have had no luck. Every time i try to run gcc i get: "sh: /usr/bin/gcc: Permission denied. Has anyone else had this problem with this ?
