Commandline utility to edit ID3 tags?
by Niki Kovacs 28 Mar '08

28 Mar '08

Hi, I'm running a webradio on our brandnew CentOS 5.1 database server. (The main purpose of this radio is fun, sure, but it's also a bit like a canary in a coalmine...) It's based on Icecast, MPD and NCMPC and works great. I'm configuring the server remotely via SSH, no X. Is there any commandline utility to edit ID3 tags? Cheers, Niki

USB printer stops working?
by Alan Goodman 28 Mar '08

28 Mar '08

I have recently attached a USB to my centos 5.1 NAS server. The printer works for about 5 minutes after the box has started but after that it stops working. CUPS says the device is busy. If I print stuff, reboot the server and go into cups it mentions an error about HAL failing, i click start printer anyway and all the documents I have printed will be printed. Someone mentioned it might be USB power saving, if this is the case how do i turn it off? Alan

OpenGL and CAD Apps
by Joseph L. Casale 28 Mar '08

28 Mar '08

I am likely going to switch a desktop over from Windows to either CentOS or Fedora and run two CAD apps that now have Linux ports. I was wondering as I can't seem to find much specific info about the support of OpenGL in RH based OS's. Does CentOS support this out of the box or do I need to do anything with it? Anyone doing this, or know of a definitive resource to point me towards? Thanks! jlc

Deleting file in /tmp directory
by Mário Gamito 28 Mar '08

28 Mar '08

Hi, This is a bit of-topic, but since it has to do with /tmp permissions here it goes. Anyway, I'm sorry in advance for posting this. I have this PHP script (simplificated here), called delete_tmp.php that basically calls external commands: <?php $session_file = '/tmp/sess_89765' system(''rm -f' . ' ' . $session_file); ?> delete_tmp.php file is owned by gamito.users /tmp/sess_89765 file has permissions -rw------ and is owned by gamito.users My /tmp permissions are rwxrwxrwt and is owned by root.root I know that the the sticky bit only allows files to be deleted by their owners, the owner of the directory or by root. Never the less, i can switch to /tmp directory and delete sess_89765 file as user gamito. If I run: $ php delete_tmp.php as root, it deletes sess_89765 file. But if I do the same has user gamito, it doesn't delete the file !!! Ideas ? Any help would be appreciated. Warm Regards, Mário Gamito

Re: [CentOS] Strange behavior from grep
by Mário Gamito 28 Mar '08

28 Mar '08

Hi, Thank you for your answer. After a little more research, I found out that the line containing the word 'gamito' is huge and yet it scrolls so fast in the screen that I can barely see it. I tried redirecting the output of the grep to a file and that huge line went in to it. So, I've tried a double grep: $ grep 'gamito' file | grep 'gamito' but without success. Well, my question now is, how do I get the word 'gamito' alone from the file ? Any help would be appreciated.

Strange behavior from grep
by Mário Gamito 28 Mar '08

28 Mar '08

Hi, It's been a long time since I've been noticing a strange behaviour from CentOS grep command. But today, I really need it. I have a file that has the word gamito inside of it. If I run $ grep 'gamito' file it returns nothing. Yet, if I run $ grep -c 'gamito' file It returns 1 which is right. The mind boggles. Does anyone ever had this problem or am I missing something here ? Any help would be appreciated. Warm Regards, Mário Gamito

Installing Postfix/Dovecot
by Giulio Troccoli 28 Mar '08

28 Mar '08

I have just installed CentOS 5.1 on my home server and I am trying to set a mail server. I have diligently followed the instructions on the Wiki - How To on the CentOS website (http://wiki.centos.org/HowTos/postfix) However I cannot send internal email (I haven't yet tried externally). Do you have any suggestions on what to check? To test it I used two normail user: giulio and federica. I logged in as federica and sent an email to giulio with the mail programme. Is this correct (i.e. using the mail programme)? There is one thing that I don't quite understand from the instructions. In section 3.1 it's suggested to set mynetworks = 192.168.0.0/24, 127.0.0.0/8 in the /etc/postfix/main.cf file. My home network however is 192.168.69.0 and actually the IP assigned to any computers in the networks start from 192.168.69.20. So I changed mynetworks to 192.168.69.0/24 and also 192.168.69.19/30 (as my server IP address is actully 192.168.69.25). I don't think this is the cause of my problem anyway, because it didn't work even with the value suggested by the Wiki page. Thanks for you help Giulio
