Six core AMD Opteron

kc0tma — Fri, 26 Jun 2009 17:30:33 -0700

I didnt order an operating system with it because I cant stomach suse, and red hat doesnt seem to let LTSP work for some reason, and because of the LTSP and my thin clients microsoft is out of the question. I was thinking Id use fedora and the K12 linux, but Im having doubts if I can get it to work with that much computing power. So my next idea was gentoo because it seems to be able to support just about any processor architecture you can throw at it, but Ive never been successful using gentoo in the past.

So maybe I could jerry rig my own custom kernel, but again Ive never done that either. I think I got myself into a world of *plum* ordering that server, but its too late now so Ill just have to deal with it. My long winded question here is: Does anyone know anything about which kernel to use with these new processors? I cant seem to find anything on google that is any use. Would the x86_64 or the amd64 or whatever it is called work? Ive got time to play around and get everything working, the current ltsp server I have will suffice for this year but Id still like to get it off my rack as soon as possible. Anything any gurus can think of will be a great help.]]>

Low level program to save a mjpeg stream

Rufe0 — Fri, 26 Jun 2009 03:04:46 -0700

Well first Ill just say I am a complete Linux beginner, but I have done vbs, js, php, html web type stuff so Im not a complete beginner to programming.

However Ive been trying to learn C and python but its not making a huge amount of sense.

I am wanting to make a simple low level program that copies an image from a mjpeg stream on 192.168.0.1/videostream.cgi for example to a variable then save that variable to a file on my system.

I am aware that there are programs out there that would do this but I still want to make my own.

Any help?
Thanks Rufe0]]>

Linux user and group managment

SpooF — Wed, 24 Jun 2009 14:59:42 -0700

How would I go about setting that up?

I know when ever a user creates a file they can give certain access to, user, group or other. If I put a user in the group programmers then if they set a file to chmod x7x then the programmers group should be able to read, write and execute right? Is there anyway I can make it so I can always access there files even if they restrict group access?]]>

OpenLDAP SSL/TLS problem with pam/nss

humbletech99 — Fri, 12 Jun 2009 05:39:18 -0700

CODE:

getent passwd

returns nothing from the ldap server, and the logs show:

CODE:

Jun 12 13:23:22 myhost getent: nss_ldap: failed to bind to LDAP server ldaps://ldap.mydomain.com/: Cant contact LDAP server
Jun 12 13:23:22 myhost getent: nss_ldap: could not search LDAP server - Server is unavailable
Jun 12 13:23:22 myhost slapd[31771]: conn=9 fd=15 ACCEPT from IP=x.x.x.x:59963 (IP=0.0.0.0:636)
Jun 12 13:23:22 myhost slapd[31771]: conn=9 fd=15 closed (TLS negotiation failure)

I have set these options in ldap.conf for the nss/pam ldap modules

CODE:

tls_checkpeer yes
tls_ciphers HIGH
ssl yes
tls_cacert /etc/openldap/cacerts/slapd.cert

and I have the following options in slapd.conf:

CODE:

TLSCACertificateFile /etc/pki/tls/certs/ca-bundle.crt
TLSCertificateFile /etc/pki/tls/certs/slapd.cert
TLSCertificateKeyFile /etc/pki/tls/certs/slapd.pem

I dont think that increasing debugging in slapd will help as it looks like its the client nss and pam ldap modules that are failing to verify the certificate. Setting

CODE:

tls_checkpeer no

allows the getent to work, but of course this is insecure...

The cert file and pem file are there with the right permissions, and I am testing this from the same server that slapd is running from right now, so the cacert mentioned in the ldap.conf file is there on the local filesystem too and I copied it to the right path...

So my question is, how do I go about debugging this? I cannot see any more logging information or options to increase logging for the pam/nss modules... and I dont know much about openssl in general (I know I should but Ive always hated it)]]>

Command Line Program Examples

SpooF — Tue, 09 Jun 2009 13:20:24 -0700

For example:

You can run the following command to see memory usage of currently running process for a specific user.

CODE:

ps -u root -o rss,command

You can add the following to remove certain commands with the given phrase in the command.

CODE:

grep -v string

You can also add the following to sum the first column and return the results, in this case its the memory used and it returns the value in MB.

CODE:

awk {sum+=$1} END {print sum/1024}

All elements together:

CODE:

ps -u root -o rss,command | grep -v string | awk {sum+=$1} END {print sum/1024}

Do you think this would be a good resource to add to the forum?

I wouldnt expect this to be a sub category, more of just an organized thread. I just wanted to get some feedback on the idea.]]>
