After having encountered this issue several times, I’m glad I have found a solution on the osdir site.

http://osdir.com/ml/gnu.screen.user/2005-04/msg00051.html

This solves:

• irssi screen hangs
• ssh timeout hang screens

The workaround for this issue: kill all “old” ssh connections to that screen that are no longer connected.  According to strace, it seems screen is trying to write to the client, which is no longer connected:

write(1, “[22;1H\33[1L\33[1;24r\33[?25l\33[24;11H\33″…, 235 <unfinished …>

In a previous post, I wrote about the release of Open Panel and OpenCLI.

OpenCLI is going to change the way we maintain systems - for too long many repetitive steps have been automated hundreds of times by different sysadmins without having produced a standard. I think OpenCLI will become the standard that covers 99% of the tasks you perform while maintaining your systems.

Tired of getting mail notifications of e-mails you’ve already seen but have not read? The default mozilla thunderbird new e-mail notification tool has the tendency to display old mail and mail that has already been moved to junk folders. When you flag your e-mail as ‘read’ when you filter out junk, you can work around the displaying of junk messages.

With this new thunderbird add-on, you can configure more: https://addons.mozilla.org/en-US/thunderbird/addon/2610

note: use “%subject” and “%sender” in the notification text to display message details. More info on these variables on the author’s website: http://tjeb.nl/Projects/Mailbox_Alert/index.html

The past months, I teamed up with the panel6 folks in their project to create a server/webhosting control panel “that eats webmins for breakfast”. I’m very happy with the results so far: the webbased GUI communicates 100% through ajax with the core system.

And it gets even better: it contains a command-line called ‘opencli’

Creating vhosts on servers is repeating the same trick every time. I know most people around me have automated this using ’setup-a-new-domain’-scripts, but handmade scripts usually lack proper errorchecking - unless you spend a lot of time writing them. With opencli creating a new vhost is as simple as entering ‘create vhost www.foo.com’ and apache is up and running the domain \o/.

While upgrading Apache to version 2.2.4-2 for a subversion upgrade (version 1.4.4dfsg1-1) I ran into errors with my auth_pgsql (or any other auth_mysql, auth_ldap or auth_* module) setup:

“Internal error: pcfg_openfile() called with NULL filename”

This is caused by auth_basic and stops the authentication and authorisation process. Adding the following directive to your auth_pgsql or auth_ldap config file solves the problem:

“AuthBasicAuthoritative Off”
It disables basic authorisation being authoritive for the authorisation process. The errors will still be visible in your logfiles, but the authorisation scheme works as normal.

When your windows image viewer is really slow in showing the image (halts on ‘Generating preview’), make sure that there are no dead links in the same folder as you are currently viewing the file in. Broken links to network drives for example cause slowdown of the image viewer. This usually occurs on the desktop, which contains shortcuts to programs or games that might no longer be installed on your computer.

Moving the images to a seperate directory solves the problem.
