Kickstart - URL command
by Jörgen Maas 09 Oct '10

09 Oct '10

Hi list, I'm fiddling with CentOS 5.5 and kickstarted installations via cobbler. In my environment I need to install using the HTTP protocol over a proxy. Does anyone know why the URL command doesn't support the --proxy method? I get an Anaconda error message stating that this method is not supported. Even though i found out about that method in documentation. Relevant section in my kickstart: # install system install url --url=http://1.2.3.4/cobbler/ks_mirror/CentOS-5.5-x86_64/ --proxy= http://5.6.7.8:12345 text firstboot --disable reboot Anyone with suggestions? Other methods of getting this thing to install over a proxy server? Thanks in advance! Regards, Jorgen Maas

looking for a decent free / Open Source flash media server
by Rudi Ahlers 09 Oct '10

09 Oct '10

Hi all, I hope someone can help me with this one. I am looking for a decent free / Open Source flash media server software which I can run on a Linux server. Adobe's Flash Media Server (http://www.adobe.com/products/flashmediaserver/) is very expensive and not within any reasonable cost range (R40K+). The Fladh Media Server uses the RMTP This is needed to run the following Joomla extension: http://www.joomplace.com/live-conference/live-conference.html which basically allows us to setup a Flash tutorial conference setup, similar to podcasts. We currently use CentOS Linux + cPanel, as well as CentOS + VirtualMin but I'm open to suggestion for other control panels as well if need be. Does anyone have any suggestions for me? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Radeon HD 4550 driver
by m.roth＠5-cent.us 08 Oct '10

08 Oct '10

Upgraded the kernel to the latest, then tried to rebuild the proprietary Catalyst driver for a Radeon HD 4550 on a Dell Optiplex 980. The install dies, with a c error. Anyone else out there succeed in building one on the 2.6.18-194.17.1.el5-x86_64 kernel? I went to the ATI website, and the "installation instructions" include that it needs a) 32 bit software (which? dunno) and b) a couple of Xfree86 packages (huh? why? dunno, probably they haven't updated this page in years). Btw, it's fine for single head, but a relatively ordinary dual-head setup, with what Nvidia calls "individual desktops" ("spanning" seems to mean the same thing on both monitors). The xorg driver seems to work for single head, but no joy with dual head. For that matter, anyone have any contacts? I'm still mousing around the ATI website trying to find an appropriate contact. mark

Re: [CentOS] error when logging into system - SOLVED

I got pulled off on some other projects and am just now getting back to this. Evidentally, I had spent too much time looking at this last week. When I opened up /etc/passwd, it was specifly the default group for the user to be 500, not 1000 that I thought I saw. I changed this to 1000, and everything works now.

sudo 1.6.9 versus sudo 1.7.2 behavioral differences with umask settings
by David Goldsmith 08 Oct '10

08 Oct '10

Two servers, each have normal user umask values of 0077 and root umask values on 0022. On the first server (CentOS 5.4 i386) running sudo 1.6.9pl7-5 (from base), here are the results of touching a file as a user, as root and as a user sudoing to root: user: touch file - result is 600 root: touch file - result is 644 user: sudo touch file - result is 644 On the second server (CentOS x86-64) running sudo 1.7.2p1-7 (from updates), here are the results of the same actions: user: touch file - result is 600 root: touch file - result is 644 user: sudo touch file - result is 600 ** this differs ** On the second system, if I downgrade sudo to the base version, it behaves the same as on the first server, so this appears to be sudo version specific rather than an i386 vs x86-64 difference. Looking at the changelogs at the package home site, I don't see anything obvious that covers this change: http://www.courtesan.com/sudo/stable.html#1.7.0 http://www.courtesan.com/sudo/stable.html#1.7.1 http://www.courtesan.com/sudo/stable.html#1.7.2 Does anyone know how to change the behavior with the umask values when using the newer version of sudo? This is causing us some issues when sudoing to update an SVN working directory used by our Puppet server. Thanks, David Goldsmith

Zoneminder
by Joseph L. Casale 08 Oct '10

08 Oct '10

I have a few dvr's that I am contemplating converting to Zoneminder (don't know any other app) and would prefer to use CentOS over fedora obviously but the only rpm I see exists for Fedora. I don't want the hassle of manually compiling this, as we have our own config mgmt. Anyone using this rpm (srpm recompiled) in CentOS or know of a solution that exists? Thanks! jlc

Thanks a lot for this check-list (I recommend it for others in the future). I had already checked most of the points, but I still played around with your ideas, without success But, this remark: > I've never done ldaps to port 636, only TLS to port 389, so some of my > comments may be slightly off-base in your situtation. made me think of checking what should be the difference between a START_TLS on a plain ldap port and ldaps on the ssl port In /etc/ldap.conf: for ldap + START_TLS this is indeed > ssl start_tls but for ldaps (my case) this should be: ssl on Changing the value of 'ssl' to 'on' solved my problem! (and this explains why my ldapsearch queries were working: as you pointed out, /etc/ldap.conf is for the configuration of nss_ldap) IMHO, the comments in /etc/ldap.conf could be a bit more explicit on the 'on' value: ... # OpenLDAP SSL mechanism # start_tls mechanism uses the normal LDAP port, LDAPS typically 636 #ssl start_tls #ssl on ... Thanks a lot for your help!

does ssh-copy-id not use "id_rsa.pub" file by default?
by Robert P. J. Day 07 Oct '10

07 Oct '10

yesterday, i was demoing how to use ssh-copy-id on centos 5.5 to copy one's public key to another machine and account so you don't need to type the password anymore. i used "ssh-keygen" to create the standard RSA-format files, then checked the man page for ssh-copy-id, which reads: ssh-copy-id [-i [identity_file]] [user@]machine ... If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used the above seems to suggest that, as long as i'm happy copying over the default id_rsa.pub file, all i need type is: $ ssh-copy-id -i barney(a)192.168.2.19 /usr/bin/ssh-copy-id: ERROR: No identities found $ clearly, that doesn't work. but if i simply add in the name of the file, it's fine: $ ssh-copy-id -i .ssh/id_rsa.pub barney(a)192.168.2.19 ^^^^^^^^^^^^^^^ any reason for that? the man page clearly states that that file is the default, but it's obvious i still need to type its name. am i missing something? is the man page wrong? rday -- ======================================================================== Robert P.
