deleting Cyrus mailbox with empty name
by Tilman Schmidt 07 May '13

07 May '13

A junior administrator of mine mistakenly created a mailbox with an empty name, by typing into cyradm the commands: createmailbox user/$lb setquota user/$lb 10000 He will of course shortly receive an extra lesson on shell variables, but meanwhile I find myself confronted with the problem how to get rid of the mailbox he created. So far all attempts have failed: [cyrus@posthamster ~]$ /usr/lib/cyrus-imapd/quota Quota % Used Used Root 0 user/ 0 user/ 10000 [...] [cyrus@posthamster ~]$ ls -l /var/spool/imap/user/ total 2180 drwx------. 2 cyrus mail 4096 Oct 1 2012 drwx------. 2 cyrus mail 4096 May 7 08:53 10000 [...] [cyrus@posthamster ~]$ cyradm -u cyrus localhost IMAP Password: localhost> sq user/$lb localhost> dm user/$lb deletemailbox: Permission denied localhost> lam user/$lb "" lrswipkxtecda localhost> sam user/$lb cyrus all usage: setaclmailbox mailbox id rights [id rights ...] localhost> sam user/"" cyrus all setaclmailbox: cyrus: lrswipkxtea: Mailbox does not exist localhost> sam user/ cyrus all setaclmailbox: cyrus: lrswipkxtea: Mailbox does not exist localhost> lam user/ Mailbox does not exist localhost> lam user/"" Mailbox does not exist localhost> ^D [cyrus@posthamster ~]$ ls -l /var/spool/imap/user/ total 2180 drwx------. 2 cyrus mail 4096 Oct 1 2012 drwx------. 2 cyrus mail 4096 May 7 08:53 10000 [...] Obviously the handling of undefined variable substitution in cyradm is somewhat inconsistent, preventing me from deleting the mailbox the same way it was created. Any ideas? TIA T.

Strange Postfix problem
by tdukes＠palmettoshopper.com 06 May '13

06 May '13

Hello, Was trying to setup postfix on my home PC. Running Centos 6.4. I don't have a static IP and use zoneedit and ddclient to keep my installation of zoneminder current. So I decided I wanted to get zoneminder to send me email alerts. Sent some test messages but none were sent. I went to webdnstools website thinking maybe there is a dns or network problem. When it checks my dns setup, everything is fine except the mail server is has the wrong IP address. The A record and the www A record have the correct IP. The IP address its reporting is one that belongs to my ISP. TIA

unprivileged users rebooting at console
by Joseph Spenner 06 May '13

06 May '13

I'm curious why any user logged in at the console can issue the 'reboot' command and reboot the system. I've tested/verified this to work, and read some older posts about this. If it were a bug, I suspect it would be fixed by now. Also, if a user is logged into the console, and then logs in via ssh from another system, that user can also reboot the system from that ssh connection. It would seem that once a user authenticates on the console, and remains on the console, they can reboot from any other/new tty. Once they drop off the console, the ssh connections can no longer reboot. If this is by design, why? Thanks!

CentOS 5 netinstall problem
by Phil Dobbin 06 May '13

06 May '13

Hi, all. I'm attempting to install CentOS 5 via netinstall from <mirror.centos.org/centos/5/os/i386> & it gets as far as formatting the disk but when it gets to: 'Starting install process. This may take take several minutes...' it hangs forever (well, a couple of hours). Dropping down in a console I see it's telling me: 'Preparing to install' then nothing. 'top' shows activity for Anaconda but very little. This is on an old Poweredge 650 with 3GB's of RAM on a secondary drive. The primary drive has CentOS 6.4 running on it quite happily so the hardware's up to it. I chose to install the 'Server GUI' packages because I was curious. Maybe herein lies my problem? Any help appreciated. Cheers, Phil... -- currently (ab)using CentOS 5.9 & 6.4, Debian Squeeze & Wheezy, Fedora Beefy, Spherical & That Damn Cat, Lubuntu 12.10, OS X Snow Leopard & Ubuntu Precise, Quantal & Raring GnuPG Key : http://www.horse-latitudes.co.uk/publickey.asc

Problem with D-BUS Centos 6.4
by AJH 06 May '13

06 May '13

Hello, I hope anyone at the list could help me... I like to open a notify by using "/usr/bin/notify-send" in my .procmailrc. Should show a notify if a new mail arrive. My script which creates that notify-send is working and if I test it everything works fine. So I inserted it into my .procmailrc, i looks like that: | perl /opt/sbin/mailnotify.pl I like to grep my mail into my script which creates the notify-send... If procmail triggers that script this messages comes up into the logfile of procmail: --- process 6975: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": Permission denied See the manual page for dbus-uuidgen to correct this issue. D-Bus not built with -rdynamic so unable to print a backtrace --- OK..I searched in the internet about that problem and found out that: http://www.torkwrench.com/2011/12/16/d-bus-library-appears-to-be-incorrectl… But if i do that and insert: "dbus-uuidgen > /var/lib/dbus/machine-id" this is not the solution of my problem...the same happens again. so my question: could anyone tell my what I do wrong? -- thanks + bye ajh

Is there a good nntp client for Centos 6 that handles SSL native?
by Rock 05 May '13

05 May '13

Is there a good nntp client for Centos 6 that handles SSL native? It was difficult, to say the least, on Centos anyway, to get Pan to post to Mixmin servers, which require SSL (so we have to use Stunnel to add SSL capabilities to Pan) on Centos. Had Pan native SSL support, this wouldn't have been a problem. Hence the question: Q: Is there a good freeware NNTP client with a Centos repository that handles SSL native? Note: Here's the abbreviated sequence to install Stunnel with Pan (but it took me months to come up with this as all the tutorials on the web fail in the little Centos details). Install Stunnel: $ sudo yum install stunnel -y Read bug reports to find a stunnel init script for Centos: https://bugzilla.redhat.com/show_bug.cgi?id=455815 Add & modify that stunnel /etc/init.d/stunnel script: http://bugzilla.redhat.com/attachment.cgi?id=325164 Configure the Stunnel /etc/stunnel/stunnel.conf file: ;setuid = nobody ;setgid = nobody client = yes [nntp] accept = localhost:2119 connect = news.mixmin.net:563 NOTE: It took me months to figure out that these two now-commented lines cause stunnel to fail on my Centos box: Test Stunnel: $ telnet localhost 2119 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 200 news.mixmin.net InterNetNews NNRP server INN 2.6.0 (20120622 prerelease) ready (posting ok) post 340 Ok, recommended message-ID <kuyt4l$e21$1(a)news.mixmin.net> From: foobar <foo(a)bar.com> Newsgroups: alt.test Subject: This is a test This is a test of stunnel to mixmin. . 240 Article received <kuyt4l$e21$1(a)news.mixmin.net> quit 205 Bye! Connection closed by foreign host. Install Pan: $ sudo yum --enablerepo rpmforge install pan -y Configure any known good Pan newsserver: [Pan]Edit->Edit News Servers->Add->(see below)->OK Address: aioe.org Port: 119 Configure a test Pan posting profile: [Pan]Edit->Edit Posting Profiles->Add-> Profile Name: New Profile Full Name: Foo Bar Email Address: foo(a)bar.com Post Articles Via: aioe.org OK Test Pan setup by reading & sending a message to alt.test. [Pan]Post->Post to Newsgroup->alt.test Now you're ready to configure Pan for SSL via Stunnel: [Pan]Edit->Edit News Servers->Add->(see below)->OK Address: localhost Port: 2119 Switch the test user to this encrypted server: [Pan]Edit->Edit Posting Profiles->Edit-> Post Articles Via: localhost OK Test this setup by reading & sending a message to alt.test. [Pan]Post->Post to Newsgroup->alt.test Note: It would have been easier had Pan native SSL capability; hence the question: Q: What nntp client handles SSL native on Centos 6?
