Hi, I have set up a server using CentOS release 6.5 with Samba and winbind and joined it to the domain using the net ads join -U command. However, when I try to run the wbinfo -u command it returns to prompt. The command wbinfo -p works. I have also tried restarting the Samba and winbind services and joining the machine to the domain again. However nothing works. Your assistance would be

Hi, I'd like to use cdrecord on the command line. I'm currently reading the relevant chapter in Carla Schroder's "Linux Cookbook". Unfortunately, some of the tricks and hints included in the book don't seem to work the same way on a standard CentOS 5 install. 1) Am I supposed to be root to use cdrecord and burn an .iso file? 2) How do I specify a device?

Does there seem to be a popular Linux distro folks use specifically for Asterisk? I'd like to move off of FreeBSD but I'm not too familiar with Linux distros. In particular, I'm looking for a free, stable, well supported distro that has a friendly community. Any advice appreciated. Sorry for asking a question that I'm sure has been asked thousands of times. Best regards,

Hi, I'd like to use SSH without password so I can use it in scripts (for example in combination with rsync to do backups). I have Carla Schroder's "Linux Cookbook" and I'm trying out the various receipts, but the one for SSH without a password doesn't work. The book is slightly dated, and I wonder if SSH included in CentOS works differently. Any suggestions? Niki

Dear R-gurus, Is there any function in R does the same thing as function subplot()in Splus? I am trying to post a pie chart onto the top right hand corner of existing bar chart. Also, Does anyone know if I can use paste() to paste the graph to another graph? Cheers, Carla Chen

One more question- is there a reference somewheres for all the built-in Asterisk macros? thanks! -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ?Carla Schroder ?check out my "Linux Cookbook", the ultimate Linux user's ?and sysadmin's guide! http://www.oreilly.com/catalog/linuxckbk/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I like to use zgsmplay to preview Asterisk's gsm files. Works like a charm in 1.2. But something changed in 1.4- they play at the wrong speed, very slowly. They sound fine in the normal course of using the Asterisk server. The file sizes seem wacko. The first example is from 1.2, the second from 1.4: $ ls -l im-sorry.gsm -rw-r--r-- 1 1000 1000 1419 Dec 5 2005 im-sorry.gsm $ ls -l
