| blackflow | Mmmmmh. iron-clad, locked down, systemd-cgroup-containerized, apparmored, unprivileged (no root master) nginx server running on Bionic. Tastes like a million dollars. With a side dish of occasional CVE corrosion in that iron, but eh... | 11:55 |
|---|---|---|
| blackflow | Ooh! Ooh! Running atop of LUKS encrypted ZFS root. | 11:56 |
| taylan | can someone help me troubleshoot my mail server? I tried to configure postfix and courier with ldap, but thunderbird can't connect to a user I defined in ldap... no idea what debugging tools are available to pinpoint the problem. they are listening on 465 and 993 on all interfaces and I can open a TCP connection to these ports from the computer with thunderbird on it. | 13:55 |
| compdoc | thunderbird supports ldap? i had no idea | 13:56 |
| taylan | compdoc: no, postfix and courier do | 14:02 |
| taylan | my problem description was crap. in thunderbird, I'm trying to add an ccount. I entered the smtp and imap hostnames, selected ssl/tls for both, but when I click on "Re-test" it says "Thunderbird failed to find the settings for your mail account" | 14:04 |
| compdoc | seems like an odd error. like its trying to autoconfigure instead of accepting your settings | 14:05 |
| taylan | by the way, the reason I'm trying to set up courier is that "apt-get install dovecot" fails. the install scripts seem not to add some users and groups they should be adding... anyone know this problem? | 14:05 |
| taylan | I'm on LTS | 14:05 |
| compdoc | anyway, Im no expert on ldap, and its early yet. hang out and ask again. maybe someone will know. mught also ask in ##networking | 14:07 |
| taylan | oh, when I manually select some auth options in thunderbird, the error message becomes "username or password invalid". I guess that's a step forward | 14:07 |
| taylan | ok thanks :) | 14:07 |
| blackflow | taylan: begin with postfix and dovecot errors, they must've logged what went wrong | 14:10 |
| blackflow | ohwait... courier.... | 14:10 |
| taylan | blackflow: see above: I couldn't install dovecot :( | 14:11 |
| blackflow | taylan: ok one problem at a time. dovecot installed just fine here on bionic. dovecot-imapd thatis | 14:11 |
| taylan | it first erred out because the "dovecot" group didn't exist. I added it manually. then it said the user "dovenull" doesn't exist, and I didn't want to continue trying to fix things manually... | 14:12 |
| blackflow | which package though? dovecot per se doesn't exist, you must be explicit about which compoentn you install | 14:12 |
| taylan | I think it was the core package that caused the errors already. let me retry. | 14:13 |
| blackflow | bionic or xenial? because it just installed fine on bionic | 14:13 |
| taylan | silly question but what's the quickest way to find out? I think I'm on 16.04, whatever codename that has. | 14:14 |
| jelly | lsb_release -sc | 14:14 |
| taylan | thanks. xenial it is. | 14:14 |
| blackflow | doesn't seem like anything like this has been reported for dovecot as bug. I wonder if there's a permission problem preventing install scripts from creating the group and the user | 14:18 |
| blackflow | at any rate, dovecot is strongly recommended for postfix, especially for sasl. | 14:19 |
| taylan | I just found this: https://www.mail-archive.com/ubuntu-server-bugs@lists.ubuntu.com/msg147608.html | 14:20 |
| taylan | sadly the mails by the original reporter don't seem to be in the archive. the subsequent reply indicates that they were able to solve the problem somehow | 14:22 |
| blackflow | status: Invalid, no wonder it didn't show for me in search | 14:23 |
| blackflow | bug #1785584 | 14:23 |
| ubottu | bug 1785584 in dovecot (Ubuntu) "package dovecot-core 1:2.2.33.2-1ubuntu4.1 failed to install/upgrade: installed dovecot-core package post-installation script subprocess returned error exit status 1" [Undecided,Invalid] https://launchpad.net/bugs/1785584 | 14:23 |
| taylan | ah neat, that has the full contents | 14:24 |
| taylan | hmm, it's not the same issue though. my /etc/group and /etc/passwd are clean. | 14:26 |
| taylan | oh damn, found the problem, and it's crazy | 14:35 |
| blackflow | taylan: what is it? | 14:35 |
| taylan | I have a ~/bin/adduser and ~/bin in my PATH. it does something completely different than /usr/sbin/adduser | 14:36 |
| taylan | hmm, one could say 'apt-get' shouldn't be affected by that... anyway, I'll rename it. | 14:37 |
| blackflow | taylan: it reminds me of the Dwarf Fortress game causing havoc in Debian, because its binary is `df` and was in PATH before /bin/df | 14:44 |
| taylan | hahaha | 14:44 |
| blackflow | so now that you got to the root of it, pun intended, install dovecot. dovecot > courier, especially for sasl. then check the logs, enable auth verbosity for dovecot. | 14:45 |
| taylan | yeah, installed it already. checking out how to configure it for ldap | 14:49 |
