General :: Dialog Output Not Readable On RHEL 5?
Mar 23, 2011
I have written a manual backup script with menus using the dialog command. When using this on a centos 5(CentOS release 5.5 (Final)) server the output is the way I would like to have it. But when using it on our RHEL server (Red Hat Enterprise Linux Server release 5.3 (Tikanga)) it is almost unreadable. This RHEL server has been installed by another company so I don't know what they have configured.Now when I try to create a dialog box it is just waiting but not displaying anything.

I have been doing a lot of research on the web to piece together the components I need to understand what is probably a very simple thing. I've read up on buffers/cache vs. physical memory and using free -m and top and understanding that output, and reviewed Red Hat's article on virtual memory. I am hoping to get some assistance in putting it all together to understand what's happening in my situation because so far I have a lot of dangling factoids and no glue. I have also referenced the thread http://www.linuxquestions.org/questi...memory-309767/ but I didn't find my answer there.
My company is running a cluster of physical web servers (they are clones so running the same OS, with same RAM and applications installed). I'll be referring to a single system although the question applies to all because they're all showing similar output. The Multi Router Traffic Grapher is showing a steady swap usage for 3-4 months now. The average usage for today is 81%. There is, as far as I know, no performance hit because of it, but a developer noticed this and wanted to know what was going on, and I'd using this opp to learn. The system is Linux version 2.6.18-128.7.1.el5, running JBOSS, postgres, Apache, and Java. Here is the output from the memory commands I have used to try and understand what's going on.
Code:
top - 21:19:27 up 159 days, 7:43, 1 user, load average: 0.52, 0.61, 0.64
Tasks: 144 total, 1 running, 143 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.2%us, 8.0%sy, 0.0%ni, 91.9%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
[code]....
So my interpretation of this output tells me that my system has 4GB of RAM installed, 23MB of free "physical" RAM, and 1.35GB of RAM in cache (according to the second line of free -m, which represents free physical memory and useable mapped memory if I understand correctly). I have a 2GB swap partition, 1.5GB of which is currently being used, and according to the MRTG is the average that has been in use since January. So the swap size isn't decreasing. Java (JBOSS) is using the most physical RAM at 1.6GB.
My question is: if I have 1.35GB of RAM cached, why is my system using all of that swap space and not using any of the cached RAM? I thought I understood that Linux is supposed to either re-use unmodified pages in cache or send older pages to disk when more RAM was needed. It seems like my system is always sending pages to disk, which I guess would normally mean I just need more RAM but, to have close to the same swap size consistently seems like there must be more to it.

I got a CD of JPG files from a photographer. Some of the files are not readable on my Ubuntu machine (they show up as X icons in the Nautilus file browser). I figured out that the reason is that they are not "world-readable" (and also not "group-readable") and they are owned by a user that does not exist on my machine. I am able to work around it by doing sudo nautilus Is there any easier way to do this? I am thinking some setting I can make on my system relating to the CD driver works?

I am not sure whether this is something that can be answered here, but I figured this is the best place to start (next to google not giving me the answer I was looking for). One of our clients are running HPUX as filesystem, however when the support guys need to report the filesystem space they keep getting it wrong. Even after someone gave them the full command which will do the calculations for them, they still seem to make mistakes. On linux the df -h works very weel but this is obviously not available here...can use to display the filesystem space in the correct formats? Even if there is a set of commands that we can work into a script and they can then just run the script.

After moving a website folder on my local development machine to another drive, then moving it back, I got a 403 error. Most of this problem had probably to do with rights that got messed up. After deleting the code and restoring it from SVN, the rights seemed allright. The error stayed however.
The setup is a bit complex, as follows:
I have Ubuntu 10.4 as development machine, trying to mimic the server as much as possible We use Eclipse + SVN and I create all projects in a local folder under my user account In /var/www-vhosts I create folders for each vhost, like this one: test.localhost test.local/index.php: includes the index file of the project
test.local/.htaccess is a dynamic link to the htaccess file in a project subfolder
I get the following error in the apache error log:
The problem seems to be the .htaccess file, or the link to it. When I empty the htaccess, nothing changes When I remove the link, the index-include produces some output (in the apache error log) When I remove the link and replace it with the actual file, I get another error:

I'm writing a script based on dialog and one of it's functions is to perform a restore with dd, of which I would like to show the progress by means of the "gauge" option of the "dialog" utility. I wanted to do this by sending a USR1 signal from time to time to the dd PID, because this results into the amount of bytes already being dd-ed ont the console screen. A simple calculation based on the orginal size would result into a percentage that can be fed to the gauge function of dialog.
The challenge I'm facing now is to launch an external script (I guess with "&" to send it to the background) that sends, let's say every 5 seconds a USR1 signal to the dd PID. That would be no problem, but how do I capture the output of this "kill -USR1" to the original script? I tested this and the output is not sent to standard ouput, so it must be that it is sent to standard error. For now I don't see a way out.

I'm using Slackware 13. When a flash app pops up the allow/deny dialog, I'm stuck because the buttons are unclickable. My adobe flash player version is 10,0,42,34. How can I fix this problem?
Edit: I'm using fluxbox. I'm using an acer notebook with a synaptics touchpad.. both the touchpad and the mouse can't interact with the dialog.

I am using Linux on my system. I don't have gui for my system, only console is there.
I have some task to create a menu box window using dialog in shell scripting.
I have to take input from user & save it in a file.
But this should like html form as e.g.
Name - .....................
email id - ..................
phone - ......................
location - ...................
Submit Cancel
Such window should be displayed on console using dialog & then user will enter his information there as Name,email id, phone,etc & submit it, then it gets saved to a file. Here submit & cancle are buttons. I have to do it in bash shell scripting. Or give me some examples like the above with shell script code.

I have changed the preference in the Nautilus file manager/browser to "Single click to activate items" and it works.
However, when I run an application, say Totem Movie Player, and select Movie/Open I am presented with a Nautilus like file navigation dialog. This is a common dialog to most Gnome applications - probably part of Gnome. Problem is, the dialog does not respect my "single click..." preference.
I have tested this in Ubuntu 9.10, 10.04 alpha 2 and CentOS 5.4 - I do not think it is distribution related.

is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.

A client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.
This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.
Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.
