Conversations on my remote user/site problem
by Oren Beck 26 Jan '08

26 Jan '08

Several folks have shared some truly worthy possible fixes. I am planning to sort them by my limited grasp of which are practical for me. There seems to be a depth of comprehension above average in our group, which is quite above mine. So, I am asking permission from those who have contacted me off list to post all the collected work. There seems a possibility of refining the best of all these workarounds into dare I propose a new distro? An assembly of all the tool kits and scripts plus a stand alone minimalist distro such as DSL or Puppy. The killer incarnation to me at least might be a package loaded from a website or sent as a mail attach. With a fallback to CD or USB media if connection is an issue. Under a doctrine of "if you have USB/CD access, permission is presumed - passwords etc can be simplified Thus we refine one path to -nsert media-reboot- automagic configures-and connects -then somehow it grands me remote KVM. An idea I had was a script to capture the IP of the remote livedistro,-have it Email that to me and then telnet etc in -- Oren Beck 816.729.3645

Linux Support Needed
by Jonathan Hutchins 25 Jan '08

25 Jan '08

Anybody currently doing linux/windows office support in the mid-KC area? There's a law office that I support, and they need occasional file restore and such. Toughest part of the deal is that they have an ancient Gentoo server on the 2.4 kernel that won't do emerge updates any more because the whole layout of Gentoo has changed. When it was originally built, they had to use Gentoo Unstable because they needed components that weren't in stable yet. If somebody's interested in taking this on, drop me a line and I'll give you more gory details.

Three low-cost Linux PCs
by Julie 25 Jan '08

>From C/Net's Week in Photos: "Three manufacturers are preloading Linux onto PCs that cost less than $200--and retailers can't keep them in stock." http://www.news.com/2300-1044_3-6227401.html?tag=nl.e434 Hope you enjoy the peek and comments that Cnet makes. :D BTW: I've been reading with great interest the thread about that "Cube" utility function in Ubuntu. I simply don't know how to REPLY to a particular post in the news letter or I would be in there asking questions...like, "What are the exact steps to get this to work for me...the n00bee trying to migrate from Winblowz XP?" ...And I laughed my arse off at that URL which led to the "story" about 'Window Shades'!!! I just about had peppermint tea come through my nose when I read about that demo to those Best Buy employees!!! They consider themselves "techies"???? LMAO!!!! ] : ) Julie @};- --------------------------------- Looking for last minute shopping deals? Find them fast with Yahoo! Search.

SVN - Apache - Microsoft Active Directory
by Lee Brandt 25 Jan '08

25 Jan '08

Anyone have any experience with this? I am currently setting this up at my work. I have set up the SVN server and Apache 2.2.3 on CentOS. SVN Serves fines just using basic authentication. Now I am trying to hook into our MS Active Directory and have been very successful at finding configurations that don't seem to work. As far as I can tell, I am not even contacting the AD server. There is no outbound traffic and notthing in the apache error logs. below is my config. <Location /subversion> # Load SVN Dav DAV svn # set the path to the repo SVNPath /var/svn/repo AuthBasicProvider ldap AuthType Basic AuthzLDAPAuthoritative off AuthName "My Subversion Server" AuthLDAPURL ldap://ldapserver.company.com:389/DC=company,DC=com>sAMAccountName?sub?(objectClass=*) AuthLDAPBindDN "CN=binduser,CN=usergroup,DC=company,DC=com" AuthLDAPBindPassword bindpassword require valid-user </Location> I haven't made any changes to the httpd.conf (other than making sure mod_authnz_ldap is installed and loaded). This is completely out of my league. Thanks in advance for any help. ~Lee

Rereading the comments alerts me they are out of date. Of course you should change "LOGIN_PASSWORD\r" to whatever you use followed by \r (expect for <ENTER> key). This does not, as I am typing, include generating the id_dsa.pub but... I just put that part in from another script. I include -X and Compression so running a GUI is possible even across slow links. Sometimes we start... vncviewer -bgr233 -noraiseonbeep -nocursorshape -quality 0 \ -encodings "copyrect tight hextile zlib corre rre raw" \ -compresslevel 9 localhost:0 To 'peek over the shoulder' of our clients. I don't advise that unless you are on the phone with them at that moment because they freak when mouse moves and screen gets typed to without them. Diverting messages from expect so your novice users will be less intimidated I leave for the readers because I have spent too much time on this already.

Remote access partition and install Linux. With a Near Zero skilled operator at the remote site.
by Oren Beck 23 Jan '08

23 Jan '08

The reasons for this situation are several at more than one location. The overview is to remotely install Linux on computers owned by non tool users, zero skills presumed of them. What I am seeking is several methods for making the process just plain work. Initial customer is my mother in Berkeley, and her social groups may join in. The minimal cold start scene will be a Knoppix or Damn small tested computer and net connection. The defined factors are: DSL or cable modem set up as DHCP. Hardware approx 2000 or newer. Working OS of XP or installed Knoppix or both.in most cases. Very Few sites with no OS. Internal HD swaps are a non starter as most of these folks are non tool using mundanes. The rest of the story is they almost all are politically or socially desiring to use Linux.by choice! With a few skeptics that "want to be shown"-more about the net than Linux as they still use TYPEWRITERS! And they often have little to no computer skills to unlearn. Short of my doing some major frequent flier miles tripping,KCLUG may be their salvation. "Someone is going to do it- why not us?" -- Oren Beck 816.729.3645
