The unfortunate truth about Exchange

Up until the last year my workplace used IMAP servers running on Linux and Solaris to manage and deliver mail. Then we decided because of the collaborative benefits, particularly with mobile devices like Blackberrys, to move to Exchange. The results have been dramatic, and this chart made by Google to espouse their GMail product reflects . . . → Read More: The unfortunate truth about Exchange

How to convert to/from DOS format in VIM…

It’s very easy, but also easy to forget how to convert to or from a DOS format file in Unix using “vim” (Vi iMproved), the Open Source “vi”. If the file is in DOS format and you want to convert to Unix, use the command:

:set ff=unix

note that “ff” is an abreviation . . . → Read More: How to convert to/from DOS format in VIM…

Disabling Firefox Resume From Crash

Though to many it’s handy, personally I find Firefox‘s “Resume from Crash” function, well, annoying. This function makes it so that if Firefox is killed prematurely that the next time you start it you get an (annoying) popup that asks you if you want to restore the previous state/page(s) that Firefox was viewing.

Custom Google RedHat Kickstart List search engine

Michael DeHaan at RedHat has created a custom Google “search engine” to search the RedHat Kickstart List archives (the RedHat mailing list “kickstart-list@redhat.com“). It looks pretty handy to not have to use other perhaps more painful tools (or get too much noise):

CrossLoop – secure remote access

A friend of mine showed me what looks like a nice (free) secure remote access solution for visually managing a remote PC:

It’s based on TightVNC and therefor has the advantage of using encryption on the control session, helping reduce the risk of prying eyes. It also has a pretty cool way . . . → Read More: CrossLoop – secure remote access

SUSE Linux Enterprise in the Americas Blog

Here’s a potentially interesting Novell SUSE blog where you might expect a little more “off the cuff” information from the SUSE development teams:

Fedora 8, NIS (or LDAP), and “gdmgreeter”

One major issue with Fedora 8 in shops that use a network user repository like NIS or LDAP is “gdmgreeter” breaks (note “gdmgreeter” is the Fedora replacement for XDM). The symptom is X11will fail repeatedly and not come up. In that case you will also see errors like this in “/var/log/messages”:

Fedora Core 6-isms

While in the organizations I have sway over we are working to rid ourselves of older out of maintenance OSes, I do occasionally run into some Fedora Core 6. When I do there are a couple of minor hacks you regularly have to do to make things work (note these are after applying the latest . . . → Read More: Fedora Core 6-isms

Good RPM documention

Good documentation for maintaining/creating Linux RPMs is difficult to find. This Wraptastic site seems to have so good stuff:

http://wraptastic.org

It appears official, but it’s hard to say since the site seems to lack an “about” to key off of.

In a related line, these two RedHat sites seem to have copies of . . . → Read More: Good RPM documention

How to create a mini-boot CD for SLES 10 SP1

If you have an older system that doesn’t have an internal DVD but you do have an external USB DVD, here’s how to build a CD to boot from. This will probably work with any version of SLES 10:
