No module named snack
by Matt Morgan 02 May '08

02 May '08

Hi everyone--I'm back on the list after some time not managing any Centos machines. It's good to be back. I'm trying to switch a server from sendmail to postfix. It's Centos 4.6. I installed postfix and system-switch-mail. When I run system-switch-mail, I get Traceback (most recent call last): File "/usr/sbin/system-switch-mail", line 89, in <module> main() File "/usr/sbin/system-switch-mail", line 76, in main from switchmail_tui import mainDialog File "/usr/share/system-switch-mail/switchmail_tui.py", line 36, in <module> from snack import * ImportError: No module named snack "Snack" appears to be a python module provided by a package called newt, which is installed: # rpm -qf /usr/lib/python2.3/site-packages/snack.py newt-0.51.6-9.rhel4 What am I doing wrong? Thanks a lot, Matt

It will not auto mount on my user account on CentOS 5. >If it's not any of the above get a new drive. Probable cause: Auto Mount of a DVD in the Teac DV-516D DVD/CD reader is not supported in the Kernel in CentOS 5 (or the Kernel on the Knoppix Live Disk v. 5.1.1); OR, there is something, somewhere, in CentOS 5 causing it not to auto mount a DVD when logged in as a regular user. A DVD can be mounted, manually, via the command line, without any problem. I believe the drive is working properly. Eventually, I will buy a DVD burner for that box. Thanks to everyone who participated in this thread and gave me things to try! If the same (unknown) thing is preventing auto mount of a DVD in an HP box Mike has,that might be interesting to Upstream as well as CentOS.

case insensitive file system
by Ruslan Sivak 02 May '08

02 May '08

We have an application that was build on a windows platform that expects a case insensitive file system. Is there a way to set one up in CentOS? NTFS should work, I think, but I feel uneasy using that under Linux. Russ

I suspect Alan is correct and that the only solution to this mystery is to buy a new drive. About 6 months ago, I bought an LG DVD Burner for my wife's box and it works fine.

You might find this article on the CentOS Wiki helpful. You can copy & paste the commands shown onto the command line and get multimedia things up and running, quickly and easily. <http://wiki.centos.org/TipsAndTricks/MultimediaOnCentOS> There is also information about the yum priorities plug-in on the Wiki. There is a link to it, near the top of the above URL.

Package change logs

Howdy, Does anyone happen to know where I can locate the changes that were integrated into a specific RPM update? I checked the wiki, the rpm query output and bugs.centos.org, but wasn't able to locate a changelog for the latest kernel update. Thanks, - Ryan

It may be helpful in pointing out > the problem. Also have you run yum update on the machine? (fstab and mtab files posted previously) I ran "yum update". The box is now 100% up to date. The problem did not go away. On CentOS 5, the Teac DV-516D DVD/CD reader can mount a CD, without any problem. However, it sees a DVD as blank. On Windows XP, it works perfectly, with CD and DVD media. I sent an email to Teac Tech Support, asking for the URL where I could download their Diagnostics for the drive and got this reply: >Unfortunately, no diagnostics are available as checking the read capabilities within >Windows XP is most than acceptable. If the drive does not work properly within >Windows or any other PC, then the drive needs to be repaired or replaced. Disappointing and I will probably never purchase Teac components again. The box is dual boot (WinXP & CentOS 5). Years ago, I purchased SystemSuite 4. I installed that and ran their generic diagnostics on the Teac DVD/CD reader and it passed. I am not positive the Teac drive is working perfectly, but I have a high level of confidence in it. My belief is that somewhere, there is either no support for the Teac DV-516D in CentOS 5, or, that something required to automount a DVD in it is not configured properly. It can mount a CD without any problem.

My belief now is that there is no support to auto mount a DVD in that Teac drive, in CentOS 5.

You forgot to include the part about being able to walk on eggs, without breaking them! :-) Sounds like a very honest job description. If nobody on this ML is interested (and qualified) consider posting on http://www.dice.com/ Not sure what it would cost you to post the job requirement there, but it's a very active site. I discovered it last Saturday. My background is mostly Aerospace, and after not working for many years, I need to go back to work. I'm a contractor, and your job description partially describes what we encounter, when we go to a temporary job assignment: abuse & lots of stress. :-) However, we get paid by the hour and for O.T. :-)

Have you tried the test of swapping the drives in - say - > boxes #2 & #3 and seeing if the problem moves with the optical drive > or stays with box, #3? Alan: Today, I removed the Teac DV-516D DVD/CD reader, manufactured October 2004, in Japan, from my daughters box. I temporarily hooked it up in my box. The exact same problem! I could not see the contents of a DVD-R, but, I was able to see the contents of my Knoppix Live CD, without any problem. So, I did not bother with the PITA of removing the DVD/CD reader from my box, and trying that one in my daughters box. I booted my daughters box with my Knoppix Live CD V. 5.1.1 and it also showed the FC6 Install DVD to be blank. I suspect: (a) The Teac DV-516D DVD/CD reader is not supported in this kernel or somewhere else in CentOS 5. or (b) The DVD/CD reader is somewhat faulty. (c) However, Windows XP shows it to be "OK" and I can see the contents of the FC6 install DVD OK, in Windoze. Also, I can boot from the CentOS5 and FC6 Install DVD's, without any problem. And, I was able to mount the FC6 Install DVD, in a terminal and install the RPM I wanted to install, without any problems. Thank you, very much, for your time and ideas! Lanny
