OK, if it is too quiet
by James Sissel 27 Mar '07

Why would a new 300G hard drive format and run Windows 2000 fine, load and run Trustix Linux 2.2 and 3.0.5 fine, load CentOS 4.4 and Ubuntu 6.06 TLS fine but when it comes time to boot them give a "Buffer I/O error on device hda, logical sector 0" and then fail to recognize any of the partitions?

Don't know, just installed the defaults. Since I cannot boot the CentOS or Ubuntu installes I can't even check to see what I've installed. MB is a Biostar 6100-939. The 300G HD is an IDE drive. Swapped it out for a newer SATA drive and it works fine. This weekend I'll put the 300G IDE in a different PC with a different MB and try it out.

Perhaps there's something funny with the ide controller that centos and ubuntu don't cope with by default, but the others do?

Looking for an install assist - happy to pay
by gregb＠west-third.com 23 Mar '07

23 Mar '07

Greetings, all... I need some quick sysadmin/consultant aid and thought this would be the best place to turn. I need a mail and web server set up: * More-or-less typical LAMP functionality. Bonus if there's web-based config of virtual domains, etc. * The MTA of your choice as long as I can easily (think: web-based admin) configure and administer multiple domains in a setup that won't get used as an open relay. Antispam/antivirus as well. * No need for DNS; I run all that out of a third party. * Webmail - Squirrelmail but, again, I'm not picky. You'll start with a fresh install of Ubuntu Edgy Eft (server edition) and SSH config'd so you can log in. However, I'm pretty OS agnostic - truthfully, I'm most comfortable with FreeBSD but whatever makes you happy. This is more a matter of time than anything for me - I'm swamped. And probably, if I'm going to be honest, I'm good enough to get it set up on the fourth or fifth try - but not the first or second. Makes more sense to pay someone to get it done right the first time. If interested, drop me a line at gregb(a)west-third.com and we can figure out the details. Thanks, Greg Brooks

Generic Remote Desktop Client
by Billy Crook 22 Mar '07

22 Mar '07

Throughout the course of a business day, I connect to any number of terminal servers, VNC servers, and citrix servers (citrix applications). I use krdc for the first two, and actually found a citrix client for linux for the last. I would like to use one application for all of these remote-graphical-desktop things though. I like krdc because it does RDP and VNC, and can scale the window and switch easily to view-only mode. AND, I want something that will accept username and password from a command line argument. Even better would be if it could auto-determine what kind of server its connecting to. If there were just three programs that could scale the window, accept username, password, and domain as arguments and indicate success or failure via return code, I'd write a bash script to do shit, and share it with you guys. I just don't know where to get the client software.

More info at: > > http://httpd.apache.org/docs/1.3/suexec.html > > Not sure if this is what you want, but using /etc/sudoers strikes > me as odd. :) Odd, yes, but it works. I was unaware of suEXEC. Ouch! It requires recompiling Apache. I should have clarified that I eventually want to market this application to people who are not able to recompile Apache. A little more research just revealed that the '*' flag at the end of the sudoers line will allow me to pass variables on the command line. Thus I do not need the /tmp file. This is the simplicity I'm looking for. Now it's down to two scripts and an entry in sudoers. Eliminating the /tmp file has eased my headache, although I still need to filter the variables coming in. Thanks, Kyle. suEXEC will be useful for a server with multiple users needing this capability, but that is a little ways down the line yet. -Jared

Giving Apache sudo access
by Jared 20 Mar '07

20 Mar '07

I have a line in sudoers which gives Apache sudo access to run *a single script* in a specific location, outside the htdocs tree: apache ALL=(ALL) NOPASSWD: /usr/bin/php -f /path/sudo_app.php Thus the apache user can run this single command. Because I can't seem to pass command-line arguments ($argv) to this sudo_app, I write a tiny tmp file. In htdocs, I have a small php script: 'app.php': <?php file_put_contents('/tmp/vars.txt',"$_GET[a]\n$_GET[b]"); `sudo /usr/bin/php -f /path/sudo_app.php` ?> ($_GET[a] represents an argument passed through the URL like this: http://localhost/app.php?a=1&b=2) Inside sudo_app.php, I open /tmp/vars.txt, read the two variables, and pass them with full root access to the rest of the script, which accesses /dev/ttyS0. Then the script deletes the /tmp files. It works, but it seems more complicated than it should be, involving two scripts, a tmp file, and a line in /etc/sudoers, in order to run a single command. Does anyone have another idea for giving an apache module the ability to have root access to /dev/ttyS0, without compromising the box? -Jared

> I reject SI byte units *because* they are SI/metric, not just because I'm used > to the original units. Count me in the minority among geeks, but I do also. The British system is superior to the French "innovation" which is based on an inaccurate estimate of the distance from the equator to the north pole through Paris. The British system is far more intricate and interesting, both in its history and its accuracy. The meter was *originally* inaccurate, and remains so, although the appearance of accuracy has lately been improved by formulas involving the speed of light. But I'm not fooled, not being a "dumb American" on the subject: Rather, an informed one who has no interest in blindly following SI/metric because I know the 200-year-old political agenda behind it, which I still have no interest in supporting, for the same reason that Brits and Americans rightly rejected it in the first place. Most people who advocate metric have no idea of its origins, and think they are irrelevant. So be it. People who prefer to study the origins of things quickly reject the metric system. > Decimal is annoying. If we're going to fix units, they should be based off > binary or hexadecimal. At least here in the US we have binary measurements > for liquids (1 peck = 2 gallons = 4 pottles = 8 quarts = 16 pints = 32 cups = > 64 gills) I wouldn't call it annoying -- it is designed to be simpleminded -- but it *is* arbitrary. The French did not develop metric because of its superiority, but they have convinced a lot of people of this fact, even though their equally innovative calendar of the same era long ago failed. The foot is not arbitrary, nor is it "the length of some king's foot." It is part of an accurate measuring system based on the extremely stable distance from the core of the earth to the north pole, which I'm delighted to use at any opportunity. But people have a hard time believing that the ancient Egyptian culture knew more about the dimensions of the earth than the fact that it was flat, and so this subject is controversial, and drifting off-topic, and thus suffice it to say that Luke's desire for accuracy is in line with his appreciation of the imperial measuring system, and I agree with him on both counts. -Jared
