No module named snack

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

Boot disk changes from /dev/sda during install to /dev/sdb on first boot

CentOS 4.6 x86_64, Dell PE2950 with DRAC5, onboard SAS RAID 1, 2 arrays.

After booting installed system, /dev/sda exists but does not appear to
be a hard disk. fdisk -l displays nothing for sda. CentOS is on
/dev/sdb and the second RAID 1 array is now /dev/sdc.

It's been suggested (in the Dell Linux mailing list) that it is
related to the virtual CD device of the DRAC. But why would it change
after install? Is it perhaps a difference in drivers that are
available in the installer vs. the live kernel?

How can I find out what /dev/sda is? Any way to force the drive order
from the CentOS side? No relevant options that I have found in BIOS or
RAID setup.

bash-3.00# ls -l /dev/sd*
brw-rw----  1 root disk 8,  0 Apr 29 05:15 /dev/sda
brw-rw----  1 root disk 8, 16 Apr 29 05:15 /dev/sdb
brw-rw----  1 root disk 8, 17 Apr 29 05:15 /dev/sdb1
brw-rw----  1 root disk 8, 18 Apr 29 05:15 /dev/sdb2
brw-rw----  1 root disk 8, 19 Apr 29 05:15 /dev/sdb3
brw-rw----  1 root disk 8, 32 Apr 29 05:15 /dev/sdc

/dev/cdrom points at /dev/hda

mount /dev/sda /mnt yeilds 'No medium found'

When virtual CD media is connected via DRAC, it is found at
/dev/cdrom1 which links to /dev/scd0

As far as I know, it is. I recall something about it emulating a
usb drive so it could be hot plugged with a new "disc" if you will.

How did you install out of curiosity?

What info do you get when you cat some of the /sys/block/sd{a b}/ files after its booted?

DRAC Virtual CD (full CentOS disk 1 of 4) in one instance, Virtual CD
with http install in another.

removable = 1, size = 0 among others.

CentOS 4.5 - mounting remote windows fileserver using smb or cifs

Hi

I need to mount a windows share on a CentOS 4.5 box running stock kernel 
etc - I have tried using cifs and also smbfs

My fstab looks like

//share/name  	/mount/point	smbfs	username=user,password=password,uid=useridhere 0 0

or the same using cifs

When i try and mount that i get the following errors depending on the share type

smbfs: mount_data version 1919251317 is not supported

CIFS VFS: cifs_mount failed w/return code = -22

i would have thought that cifs was the way forward but any ideas? These use creds are being used on an ancient
7.3 box and they work fine

thanks

Re: CentOS 4.5 - mounting remote windows fileserver using smb or cifs

This works for me...
In /etc/fstab:-
//share/name    /mount/point           cifs    
_netdev,credentials=/etc/samba/cred.txt 0 0
In the credentials file:-
username=your-windows-user
password=XXXXXXXXXXX

Make sure the credentials file is owned by root and only readable by root.

Regards,

Ian

(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.
