I am helping a local genealogy society set up their research center. They want three workstations and a single data server. The genealogy program of choice was GRAMPS, which I have used for years a Wonderful program! No data is going to be input on the workstations the users are simply researching existing data on the server.
Since several RDP-based Wyse thin client units were available for free as were monitors and keyboards, the decision was quickly made to use an RDP based client/server system. Using VNC was unacceptable due to its speed and latency issues, plus, it isn't supported by the Wyse thin client units ONLY RDP and Cytrix.
Using Microsoft's server OS and Terminal Server package was far, far beyond the society's budget. We briefly considered equipping a Windows XP box with a copy ThinSoft's RDP server package, WinConnect Server XP, but its $300 price tag was still too much for the society.
The decision was to use Linux for the server. At first we considered LTSP but it is oriented towards PXE net boots and, while this may have worked, its complexity scared us off and we opted for what, we initially thought, was a much simpler solution XRDP.
We were right and wrong at the same time. It is simple to set up very simple, but the lack of documentation places many pitfalls in front of you, PLUS the solution is distribution dependent.
I spent many hours on this issue. There are numerous sources on the web citing solutions to running XRDP. Unfortunately, they all involve running vncserver against the destination logins. This is NOT what we desired. We wanted to be able to boot up the host system but not login at all, yet still be able to connect to a session via RDP.
I tried numerous distributions and eventually spending a lot of time going through the xrdp source code and planting out my own debug messages in /etc/xrdp/startsm.sh to output to a file in /tmp. Putting in ps -eS >> /tmp/xrdp.txt was particularly useful because it showed that xrdp/sesman DID launch an Xvnc, meaning that it was unnecessary to pre-launch vncserver, as most pundits recommend. The solution was figuring out how to connect to the Xvnc session created by sesman.
I discovered the solution somewhat by accident. It seems that the files created in the destination user's .vnc folder by vncserver were interfering with xrdp/sesman. Here is what worked. 1.Starting with a nearly virgin install of Ubuntu 10.04 beta 1, installed two users intended to be accessed for remote login via RDP. That is ALL that I did I never even logged into them. 2.My first entry xrdp.ini was unmodified except that ask was deleted from username=. Everything was unmodified.
3.Using tsclient on another machine, with the desired username, that was NOT logged in, and password pre-filled, I connected and received a nice Gnome desktop. 4.The session was on 5910. 5.While keeping this session active, I logged into the next login created for remote access and received my second nice Gnome sesktop on port 5911 automatically. Xrdp-sesman DOES automatically launch Xvnc in a useful way!
I can ONLY get this to work on Ubuntu version 10.04 e/w Gnome. It fails on CentOS 5.2, Xubuntu 9.10, SuperOS 9.10 and Lubuntu 10.04. In all cases xrdp was version 4.1.1, so the issue is not with xrdp/sesman it lies within the OS what, I do not know. I did not test KDE at all.

in Debian Lenny, using TightVNC 1.3.9 I can setup a VNC server manually by using
Code:
vncserver -query localhost -once -geometry 1024x768 -depth 16 :1
But then, as I have read is a better option, I use xinetd with the following configuration:
Code:
service vnc-1024x768x16
{
protocol = tcp
socket_type = stream
wait = no
[Code].....
In fact, I was considering that the problem was with xinetd, but I have other services setted up with it (telnet & ftp for example) and I can use them correctly.
So now I'm lost with this, what else am I not considering with VNC service through xinetd? Where can I find logs or useful information to get a clue about this problems?
When I bring down a certain machine with some nfs mounts using init 0, it hangs forever while trying to bring down the mounts, but if I bring it down using halt -p (which I've read just calls shutdown if I'm in init 3), it comes down in a timely manner. I've also read that shutdown still calls all the rc.d kill scripts just like init 0, so what is actually the difference between them? Is it this:
Quote:
All processes are first notified that the system is going down by the signal SIGTERM?Does init not do that? I'm not trying to directly troubleshoot why NFS makes me hang with init 0 at this point, just wondering why shutdown works whereas init 0 doesn't.

I used the cmd "vncserver" to start a vnc session, and it created a log file like this "/root/.vnc/linux-vzra:2.log". As time going on, the file "/root/.vnc/linux-vzra:2.log" became bigger and bigger, it is too huge indeed. How can I start a vnc session without a log file?

I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

All five of my computers are connected to the switch, actually. The only one that won't talk to any sites other than https secure sites is the Linux box. I am not well-versed in the inner workings of Linux and need some help in what I need to do so that regular http sites work.

View 6 Replies View RelatedI recently got a cable modem from Comcast, and connected a Belkin F5D7230-4 wireless router to it, then connected my computer and an Xbox 360 to the router with ethernet cables.
My computer dual-boots Ubuntu 9.10 and Windows 7. In either operating system, the wireless connection is flawless. In Windows, so is the wired connection. But in Ubuntu, there's a lot of trouble with the wired connection -- specifically, while I can connect to the router and to the Internet, and while I can use ping, dig, traceroute, etc., to verify connections to remote hosts, Web browsing, or anything else that uses http, works only for a few Websites, and then only erratically.
I don't believe it is a DNS problem -- testing with ping, dig, etc., demonstrates that, and I have also tried using alternate nameservers. I also don't believe that it is an issue with IPv6, as I've tried the fixes usually suggested, including editing the grub configuration to disable IPv6 support in the kernel and verifying that IPv6 was inactive. I've also tried using local dns servers such as pdns-recursor. None of these things seemed to help.
Also, perhaps unrelated, but disturbing: my computer has locked up a few times while testing the wired connection, and I had to use a hard reset to restart the computer.
I am having an issue with my server I have setup. I have apache running and can access the files via all other computers on my network via the ip address i have it set to default to the /var/www folder with index.html as the main file. I am however having issues trying to access it from my other IP the one i found at what is my ip. I have even setup a no-ip address to it. I've forwarded port 20 and port 80 i've even given it the default dmz. I disabled the firewall on my router and I checked and my Ubuntu machine doesn't have a firewall whatsoever i can access my outside ip on the local machine and have access the problem i'm having is trying to access it from anywhere but home.

View 7 Replies View RelatedI installed nVidia drivers for Ubuntu 11.04 but when I went to restart the computer (to complete the installation) it froze on the splash screen at the third "dot" and I had to turn off the computer manually.
I can shut down the computer, but every time I restart I get the same issue (except sometimes only the "dots" appear with lines of code running in the background).
I read on-line that hitting "F1" or "ALT + F1" right before the splash screen appears might work...but it doesn't.
My concern is that maybe the nVidia driver is "activated but not currently in use" because it didn't install properly due to the whole not restarting on it's own thing.

View 4 Replies View RelatedIn summary, after updating from 11.2 through 11.3 to 11.4, normal boot works fine, failsafe mode hangs with two fatal errors - "Module atiixp not found" and "Module ide-pci-generic not found". i would like to fix this a) so I have a recovery position b) so I learn a little more. As 11.2 has gone out of support I decided to embark on the upgrades to 11.3 then 11.4 using the zypper method described on this site. I think failsafe boot worked ok with the original 11.2 install, but I never had to use it in anger, so I can't be 100% sure. I did not test failsafe in 11.3, just checked that the typical cd set of applications seemed ok before proceeding with the upgrade to 11.4.
I have an AMD processor, chip set and an ATI 3800 series graphics card, so I added the ATI repositories for 11.3 and 11.4 as i worked through the upgrades. At 11.4 there were some graphics glitches during normal and failsafe boot which were successfully fixed by adding "nomodeset" to both boot options. Normal boot works fine but failsafe boot hangs with the error messages above. Searching for failsafe boot errors is unhelpful since, in all cases I have checked, normal boot fails too. I did try removing "Xfailsafe" from the failsafe options which produced no change.
I am guessing that, in failsafe mode, the ATI drivers are not loaded into the kernel and the idea is to default to some safer drivers which, in my case, are not present for some reason. However, there seems to be little information on the origin or purposes of atiixp so I don't know how to go about fixing this. I have not really researched the generic pci driver issue, but I am guessing that this is a fall back when the expected atiixp is missing.
