I have a custom PS1 that I would like to use for my user account however when I view my users .bashrc file, there is no line entry there for 'PS1='. Can someone please tell me if I have my own custom user PS1 line entry, where do I place it so I can have some extra function and colors in my RHEL 5 system.

User input will be via the said touchscreen, and audio output will eventually come into the equation. The target vehicle(s) will be extensively modified for the project, and I'm hoping the software will eventually override features such as the immobiliser, so an extremely fast boot time will be essential.
I have one of those Via C7 fully integrated mini ITX motherboards, much of the onboard hardware will be useless besides two USB ports and a SATA port, so could be completely removed from the kernel if necessary to achieve a fast boot. If some BIOS hacking is required I'd happily look at that too. I'm a recently graduated software engineer, and can comfortably use Linux (I'm using openSUSE for developing the software) but don't have a clue where to start with the OS; if I should be downloading and modifying an existing distro or trying to build one from scratch somehow?
I have ubuntu 10.10 installed on my computer in dual boot with windows 7, but i am using a 27-inches Samsung screen through an hdmi cable to connect my computer. whenever i try getting on ubuntu, i cannot see the top and bottom of the desktop (so i cant access the menu bar or anything!)(while using my spare vga cable) i tried downloading the nvidia driver & utility for my video card (gtx 460), but even using that, i could not setup my screen resolution manually. When i setup my windows, i was able to manually setup a custom resolution (i.e. 1842x1026) through the nvidia utility to be able to get the screen the fit properly.
I was wondering if there is any way i could do the same for ubuntu, perhaps through terminal.
I'm trying to set the default apps using gnome-default-applications-properties. In previous versions I was able to set custom apps for everything. Looks like Gnome3/Ubuntu 11.04 doesn't let me do that for, say, the mail reader. I'm one of those people who still use Alpine, and in previous versions I was able to set the default to run an xterm (well, aterm) which auto-ran alpine.
This version, looks like that's not there. I'm wondering if there's a way to set that anyway. like registering a script I write as a "mail client" so it's available in the chooser. Second... and almost MORE annoying... the "Terminal Emulator" default app DOES have a custom option. But it also recognises that I have aterm installed, which I want to use as the default app... however, since it has an aterm option, it won't let me enter aterm as a default command. Which I want to do because I want to modify the commandline options. But if you choose "Custom" and type "aterm" into the Command field... it ERASES your commandline options and puts it's default sterm options in!
I'm having difficulty setting custom ls colors in xterm. If I understand it right one can edit the system-wide file located in /etc/DIR_COLORS to modify every terminal or customize xterm; I chose xterm mostly because the other terminals I never use. Here is my .bash_profile and .bashrc respectively:
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
if [ -f /etc/bashrc ]; then
source /etc/bashrc
fi
alias ls='ls --color -F'
PS1='[e[1;32m][u@h:w]$[e[0m] '
When I use the login shell, the colors are different than xterm in that they are not as bright; furthermore, I marked out bold fonts in .Xresources:
!xterm colors
xterm*foreground: #d3d3d3
xterm*background: #000000
xterm*boldColors: false
xterm*cursorBlink: true
xterm*cursorColor: white
xterm*loginShell: false
xterm*faceName: Liberation Mono
xterm*faceSize: 10
So, there must be a file around somewhere that is changing the colors between the interactive and login shells. Also,
man xterm:
color6 (class Color6)
color7 (class Color7)
These specify the colors for the ISO-6429 extension. The defaults are, respectively, black, red3, green3, yellow3, a customizable dark blue, magenta3, cyan3 and gray90. The default shades of color are chosen to allow the colors 8-15 to be used as brighter versions. How does that get anyone anywhere with setting the color? It doesn't say what color (class) is assigned to which file specifically, thus adhering to the distribution-wide color codes. Perhaps I am making this more difficult than it should be.
I am using the elementary gtk theme, but I wanted to have my gnome-panel have a set custom background, so I went into the 'gtkrc' and commented out "#include "Apps/panel.rc"". This worked perfectly but, the right click menus and drop down menus changed color which conflict with the icons that I am using.

View 1 Replies View RelatedI just know it has to be possible to let two users (since I have two kids) share the same PC at the same time using a 2nd graphic card, two displays, two keyboards, two mice. I have seen one 10 year old "how to" which just didn't seem like it would fly with today's XFree/DBUS/all USB setups.
Does anyone know how to do this? I would like each user to see a log in screen and log into a GUI desktop (it doesn't have to be KDE, but that is what we have been using). The MB and the video card use the same type of GPU. The PC has a dual core AMD, and 4 GB of RAM, so the resources should be fine for school work, KDE Educational software/games. Other than squid, there isn't particular server running on it either, so resources should not be an issue.
Ubuntu 10.10 Server is loaded. Openssh has been loaded.
I have multiple users which need access to server via ssh.
My impression from reading about ssh is that a key needs generated for each person. Thus, each key will have a passphrase that is unique to them.
In /etc/ssh/sshd_config, the default sshd_config suggest using:
%h/.ssh/authorized_keys
My assumption is %h is a variable that will allow the current user to use the public key stored in his home directory under the .ssh folder in a file called authorized_keys. Is their a command string that automatically populates the authorized_keys file?
I am surprised that even though there are a number of hidden (e.g. .****) files located in the home folder, there is not one automatically generated as .ssh. It appears I have to create that directory myself. I am especially surprised by this since it appears the instructions for generating a key seems to load the key in the home directory instead of proceeding to create a .ssh folder to store the keys in.
It is not clear, but it appears that the public key needs to be copied or appended to the authorized_keys file, but, using the scheme above, the public key needs to be copied or appended to each users authorized_keys file instead of appending all public keys to a single authorized_keys location.
It then appears that each persons authorized_keys file needs permissions set to 600.
It also appears that if I decide to use RSA instead of DSA, I would do the same thing above but would use authorized_keys2 file instead.
Why doesn't the home folder which gets automatically set up for each user automatically get a .ssh folder generated? i.e Why does it have to be created by hand? Does it need the same permission on the .ssh folder? ie 600?
My aim is to allow many to log on via ssh simultaneously and then allow many to simultaneously vnc into their respective gnome desktops.
I'm having trouble breaking down permissions in linux. Here's the scenario. I have two users: UserA & UserB with each having to ownership and access to directories myDirA and myDirB respectively.
UserA --> /source/myDirA
UserB --> /source/myDirB
I need to set the permissions so that userA can access myDirA and myDirB. There are other users and directories but they should not be able to view outside of their own directories (which is the way it is now). I don't have groups set up for them and I'd rather not change anything else but just the permissions.
rwxr_x_r_x UserA
rwxr_x_r_x UserB
They're read/write/exec permissions are identical.
In our organization there are around 1000+ users are using mails. The mailing system is implemented under RHEL using postfix and dovecot. For user based quotas i have implemented Disk Quota. But the problem when i want to edit quota for multiple users with similar limits i'm doing "edquota user" for every users. It seems very difficult. Now I wanna know:
1. Is there any way to edit quota value for multiple users at a single shot?
2. Also there is any method to send alerts mail to the end users on disk utilization?

Whenever I login or restart the computer, my resolution gets reset. I think it may have to do with my setup being connected to a 18.5" HDTV. Is there a way to set custom resolutions in the OS, so that Nvidia and OpenSUSE can recognize them?

Im an IT manager for a small company with a small ammount of users. We already use linux for our data server and I would like to implement a domain controller. All of our user machines are WIndows XP pro.
Ive been reading up on using OpenLDAP as an alternative to active directory.
What I want is just a simple active directory like server, with a GUI if possible.
What do I need to look at and how would I go about setting this up? Im fairly proficient with Ubuntu already, I just need to be pointed in the right direction.
Is it even possible to have my windows users be able to log in to their machines using an ubuntu domain controller?
Just spent three whole days barking up the wrong tree, solving Fedora 11 and Fedora 12 boot failures because the correct hypothesis was illogical: installation did not update/modify the initrd.
The first couple of times I installed Fedora 11 on the HighPoint Technologies RocketRaid 2640x4, the installation inserted my "custom" driver module (rr26xx) into the initrd, permanently, so that the system booted off the controller card for which the custom driver was inserted. (I yelled about this success in this thread: [url]
My most recent installs of BOTH F11 and F12 on the RocketRaid failed to properly set up the boot. It turns out that the "rr2640" module I "slipstreamed" into the installation process was *NOT* permanently added to the initrd by anaconda. (F12 gave me "no root device found boot has failed, sleeping forever", on boot; F11 hung also, without such error, I presume, during the init script execution). Because of limited resources and time, I only know for sure the module was missing from the F11 initrd, and am ASSUMING the same was the case with F12.
The only difference between the successful installs and the ones with failed boot is that the successful installs were made on a single-drive (JBOD) mode on the controller; whereas, the failed ones were placed on RAID 5. But, AFAIK, the created logical device for the card is "/dev/sda", in both cases, and the kernel can not distinguish between the two cases (or can it?). Thus, the inconsistency cost me a lot of time, and is still inexplicable to me.
Question: What is the best way to deal with custom drivers, today? There are custom spins, and many tools, like isomaster. Stupid question: Is there a way to modify the initrd inside an installer ISO -- be it for CD/DVD/USBboot drive -- beefing the init RAM disk with whatever modules you'd like, for the boot process (using, say, isomaster)?
And what makes anaconda understand that a module must be added to the initrd ? How can one force anaconda to do so?
How does moving to dracut as the initrd tool affect any/all of the above?

I work as an system administrator for AIX and Linux servers. We have an FTP server running in Linux which has shared folders to Windows domain using Samba. The new requirement is to map users created to Linux machine to Windows users in such a way that, when a user logins into Windows machine with an ID say "X123" in domain "TEST", his access control to the samba shares should reflect based on the same user ID created in Linux machine.(FYI. Both the Windows and LINUX machines are in same network and domain). Please let me know the step by step procedure to configure Linux machine (smb.conf entries or any new file to be created for user mapping) to identify Windows user Login and provide access restrictions accordingly.
