Design of Remote Accessibility application

Amit Kumar Saha [amitsaha.in at gmail.com]

Mon, 19 Mar 2007 22:17:44 +0530

Hi list One of Google's SoC 2007 ideas by Ubuntu is

Remote accessibility

Ubuntu should have an easily installable and enable-able feature to allow remote access to your desktop, files, and other resources over the Internet. This could be accomplished via IPv6 when available, dynamic DNS (i.e. dyndns.org) and UPnP when not. Ideally everything would be ssh tunneled, with simple clients for Windows, Mac, and Linux distributed on USB keys or CD-R's. The client could rely on public key authentication and present options for VNC (or NX) remote control, drive mapping, or other resource sharing once connected. When appropriate, it should also allow read-only anonymous access if the owner has enabled it (for websites and shared calendars, for example).

Any thoughts on how we could implement a Simple, Bare Bone Remote access software?

Changing permissions via Web tool

[[[ This came in with no Subject at all. -- Kat ]]]

Dear list,

Hope everyone is well here. I am in search of some web based tool for linux server and may be some one of you suggest me some possible solutions.

I am using apache and webdav in a linux server. So developers can create/edit their scripts by accessing webdav and can check it through apache. Now not every one has to write permission on all the folders under the htdocs. since webdav authenticate user by LDAP so it can be solved by the <limit> tag in httpd.conf

reference   http://tldp.org/HOWTO/Apache-WebDAV-LDAP-HOWTO
Based on the Project requirement I have to modify the read/write permission of the developers frequently. Is there any web based tool so that this permission changing can be done from a browser ? I need this so that the project manager then do this from his windows machine.

OR is there any other solution to do this ? I left samba as there was a problem to edit files on linux by dreamweaver from windows because of time server problem. So any other way ?

thanks for your time.

Dual boot hard drives using Lilo?

Toby.Upham at mydata.com [(Toby.Upham at mydata.com)]

Wed, 14 Mar 2007 07:04:40 -0500

Good Day!

I have a bit of a challenge on my hands that I think you can help me with. My company (as listed below) makes automated computer placement machines that run on a Linux platform. We have used RedHat exclusively for years. Recently, we have upgraded to a Fedora version.

Into the Linux, we have our own GUI that is used for menu's, data entry, etc. We call it TPSys (Test and Place System). Well, there are many versions of TPSys that have been released over the years. Each version gives new features, some mechanical support, many software improvements.

I am the corporate trainer for this company. I am in a situation now where we just released a new version of the TPSys. Many customers that we have won't be elegible or just won't get the new software, so I'm in a situation where I now have to offer courses on older TPSys software, as well as new! I need to have my demo machine running the software applicable to that course. Short of changing the hard drive each time, I would like to have the machine be a dual boot system so that I can choose.

I have several options at hand. I have a secondary IDE spot that I can put a slave H/D, or, I can partition the drive (it's 80Gig, where we really only need a 40Gig partition to run).

My question for you guys is this...... if I edit the lilo.conf file, there is a boot line. The standard line that is in my machine is "boot=/dev/hda". What do I need to add in order have the choice of which hard drive to boot from? Is there a way to do this, and do you know of anyone using this in a practical way?

I really appreciate your time. Thank you in advance.

Upgrading from RHEL v3 to v5

Jesse Fitzgerald [jesse at nursingnet.com]

Mon, 26 Mar 2007 06:41:07 -0500

[[[ Please do not send in text with "smart" quotes! And please use a proper .sig delimiter - two hyphens and a space followed by a newline! -- Kat ]]]

Hello all. I'm running Redhat Enterprise Linux version 3.0 with an active RHN subscription.

Linux 2.4.21-47.EL #1 SMP Wed Jul 5 20:30:36 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux

I want to upgrade to version 5.0. I?m a bit anxious though. I only have a few users, but have spent a lot of time getting everything running well on my box. My question: If I install Red Hat Enterprise V5 using the upgrade option via the anaconda installer, will I loose any of my data or applications? I know that doing a clean wipe and reinstall is the BEST solution, but if possible I would like to upgrade.

Here is what I'm specifically concerned about loosing: Apache, MySql, PHP, Qmail, Vpopmail, and various other small applications (Webalizer, etc?). All of the above have been compiled from source. I'm also concerned about stuff in /usr /usr/home /etc and /var being overwritten.

I hope my questions aren't too silly. I'm a novice with basic administration experience. My server is not a mission critical commercial machine. Small variances caused by the upgrade would be easily tolerated.

Thanks in advance for any info you may have.

Kind regards,

- --Jesse :)

Time Woes

VIGNESH [vignesh1986 at gmail.com]

Tue, 6 Mar 2007 21:25:59 +0530

Hi! I have 3 distro`s installed in my system , Debian Etch , Xubuntu Feisty and PCQLinux 2007(Based on Fedora Core 6). My TimeZone is Asia/Calcutta. Is there anyway I can make all the distro`s show the right time.I don`t want to use NTP since the system is not connected to the Internet all the time.. Since Each time I boot into a distro it adds 5:30 to the system clock and shows it as the time. By afternoon it shows 10 pm the next day ! Is there anyway to make them show the right time ?

Cheers! Vignesh

XDMCP and sound redirection

Hello, all. Anyone know how to redirect the sound when in a remote X session vie XDMCP? I don't mean telling the sound server where to send the sound, I mean have it redirect the /dev/dsp0 back to the computer that is being used.

Thanks, let me know if you need more info, I'd include more, but I'm short on time right now. Sorry.

Followup: Schema for nmap XML Output

I know I've seen worse uses of XML, but I can't remember when - the useful part is just a CSV blob. This is more compact than a 'proper' use of XML, but it makes it harder to work with using XML tools: the part that looks most interesting here is (in XPath) /nmaprun/scaninfo/@services

(When I want to test simple XPath expressions, I load the XML into Firefox and use this bookmarklet):

 javascript:var r=prompt("Type your XPath here",
 '');alert(document.evaluate(r, document, null,
 XPathResult.STRING_TYPE, null).stringValue);
It only works when the result is simple text, but that's normally all I want to find.

Um... why?

FWIW, MySQL 5.1 has the ability to import XML directly:

How about the schema used in the XML? Or that used by nmap2sqlite (see below)

> Please point out any similar works

nmap2sqlite (http://search.cpan.org/~apersaud/Nmap-Parser-1.05/tools/nmap2sqlite.pl), which comes with Nmap::Parser (http://search.cpan.org/~apersaud/Nmap-Parser-1.05/Parser.pm)

Running Linux from Vista's bootloader

Anyone point me to any howtos or documents on running Linux from the Windows Vista bootloader..?

I do have a program called EasyBCD which will let me edit said bootloader - I'm at a loss as to where to put the GRUB bootloader so Vista will find it...

Mandriva 2007 - WiFi cards cannot find network

OS [osavill at uklinux.net]

Thu, 8 Mar 2007 21:56:26 +0000

I have taken some Ethereal logs

In Mand 2007 it does repeated DHCP Discovers over and over again and gets nothing back.

In Mand 2006 it does a single DHCP Request and gets a DHCP ACK back with its inet address.

I don't know the mechanics of who sends these DHCP signals but I am guessing that DHCP Discover is in some way incorrect for my setup. Does anyone know how to get it to send DHCP Request instead ?

Thanks, Owen
