View 7 Replies View RelatedI am using red hat 5. It is asking me for a user name at the terminal. I do not understand what it is asking of me. A user name was never established during installation of the program. it did ask for a root password during installation which i provided. At the terminal i did try typing "root" for the log in and the actual root password for the password. It gave me administrative access.
However, i don't know the correct command that will take me to the desktop. For windows i simply typed in win or exit to go to the main windows desktop. Linux is foreign to me... can anyone help? I would be greatful for the advice. I am a windows junky from way back.
I recently set up a family computer for a friend, and now his son is "experimenting" with the terminal (randomly entering commands). since he could accidentally do something bad, I am supposed to prevent him from using terminals, but only as hi user. I tried vlock and away, but with vlock it says 'this terminal is not a virtual console', and away can't seem to lock all consoles.

However, I'm also very much in the habit of using the nautilus-open-terminal extension for launching new terminal sessions.
I'd like nautilus-open-terminal to launch Terminator rather than gnome-terminal.
A quick search of my system and the web didn't reveal anything. i didn't find a gconf setting to control this. A quick look at the source code didn't help much either.
I have a problem that I can't seem to figure out. I can easily create a .sh file that will execute a command in Terminal, but as soon as it executes the terminal disappears. How do I get it to stay? My idea is to have the keyboard shortcut "ctrl+alt+del" open a .sh file with the contents "ps ax". Then it would be just like having a task manager; the terminal would open with "ps ax" already executed, and all I would have to do is kill the process number.

I recently did a fresh install of Ubuntu 10.10 64-bit. After installing the ATI drivers, I had to tweak GRUB to get the nice splash screen back during boot. Then, I installed drivers for my TV Tuner (Hauppauge 2250). The card works fine. However, my boot now goes splash screen to a terminal login for around 10 sec where system messages also show up to the GUI Login screen. I was wondering if there was anyway to return to a normal boot.
View 3 Replies View RelatedI'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.
And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.
I am using the sudo command to log on locally as another user by the following command:
sudo -u theotheruser -s
or
sudo -u theotheruser sh
As I see it, this initiates a new shell with the mentioned other user.However, this doesn't load that users profile from his home directory.Is there a way to automatically read the users profile when login in with selected command? I am mostely interested in getting a working prompt when logged in.
Naturally, hiding the graphical grub screen on a regular installation is easy, by adding either "timeout 0" or "hiddenmenu" to menu.lst. But on a live boot, there seems to be no menu.lst - at least no accessible one.
Although, in some kiwi image types, you can specify boottimeout="n" in the image description's type element, it does not have the intended effect. Here is an example. The following type element's boottimeout attribute will invoke the first grub menu item instantly. Changing the value to zero, not only does not hide the grub screen, but seems to restore the default 10 second time out.
<type image="iso" primary="true" boot="isoboot/suse-11.3" boottimeout="1" hybrid="true" flags="clic"/>
Is there any way to hide the graphical grub screen in a kiwi live boot?
When I run the command << kiwi-ltsp-setup -n >> the process gets to the point where it starts "Retrieving repository 'http:__download.opensuse.org_update_11.3' metadata" What do I change so that it will read from my local update repository. The local update repository is already listed in my yast repositories while the ttp:__download.opensuse.org_update_11.3 is not.

View 2 Replies View RelatedI'm trying to complete the porting to RHEL 5 of a commercial application that we've had running on AIX and SCO for decades. It originally ran on dumb-terminals, and even now runs on dumb-terminal emulators that run on Windows. We have thousands of customers, many of whom we'd like to migrate to Linux. We're pretty much done with the port, with the exception of this little glitch we're having with pseudo-ttys...
Our app utilizes pseudo-ttys, such that sub-portions of the application run under a screen manager that provides for screen-switching of multiple instances of the sub-apps on non-GUI terminals, some of which are still running serial. In this regard, it is not unlike the GNU "screen" program. However, it also supports file transfers over serial links using zmodem, and requires the ability to switch in and out of a fully 8-bit transparent mode where the screen switching keyboard commands must be ignored.
On AIX, we're using the BSD TIOCUCNTL (UIOCCMD) capability to send commands from the sub-app to the screen manager. TIOCUCNTL provides custom user ioctls and is an ideal way to solve the problem. It is not implemented on Linux, and the "alternative" of TIOCPKT does not provide arbitrary ioctls so at best we'd have to commandeer some of the existing TIOCPKT ioctls for our own use if that's even possible. TIOCPKT seems like a hack, it apparently was implemented not as a general mechanism but to solve problems specific to rlogin/rlogind.
SCO didn't support TIOCUCNTL either, so years ago we used the SVR5 alternative of putmsg/getmsg. This is a streams-based mechanism of sending control information over streams separate from the data. While RHEL 5 seems to have man pages indicating these commands exist, and in fact you can link programs using them to libc without errors, they are apparently stubbed out and return "function not implemented." This seems to be, according to this Wiki, due to certain Linux factions deeming that streams are "technically inadequate":
Certainly, I would agree that a streams implementation that is incomplete is undoubtedly "technically inadequate."
At the same time, it would appear that the SVR5 method of pseudo-tty is now the recommended implementation, the BSD one being "deprecated" (not to mention, also incomplete on Linux, given TIOCUCNTL is missing):
So here I am trying to figure out how to solve the problem. I have found a library that apparently implements the getmsg/putmsg commands for Linux, called libLiS. However, according to IBM, it has a problem with SELinux:
We've had to disable SELinux for other reasons anyway, so this is not a show stopper for us, and I am actively exploring using it as our solution. However, I've never been exactly crazy about the idea of depending on disabling security features to make something work. But, there's something to be said for the compatibility it would offer for our apps.
However, it occured ot me that we are probably not the first to have this problem, and was wondering if perhaps there is another solution that we should consider.
It has occured to me to use named pipes, but this would be rather ugly--we'd have to maintain a directory full of hundreds of named pipes, probably named after the associated ptys that the sub-apps could use to issue control commands to their screen manager, and the manager would have to monitor these pipes for commands, etc.-- certainly possible, but it seems like it might be re-inventing the wheel a bit, or at the very least, is a somewhat kludgy work-around to the apparent lack of any user-customizable control mechanisms in the pseudo-ttys. And we'd have to support it in addition to the code for the other methods since those platforms aren't going away anytime soon (SCO death-throes notwithstanding).
I use mpssh or pssh to issue commands to multiple servers. Problem is that some of the commands require pseudo terminal and won't work with these tools. This will work just fine: "ssh -t user@server command" as stated under SSH man: -t = Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g., when implementing menu services.
Multiple -t options force tty allocation, even if ssh has no local tty. So, is there a workaround for the above tools? Or is there any other tool for multi server administration that will work? If you are not sure what I am talking about just try executing "ssh user@server top" and "ssh -t user@server top" to know exactly the difference.
Perl has the concept of pseudo virtual files where data can be appended to the end of the script, & Perl will treat it as a legitimate source of data:
Code:
$ cat pseudo_file.pl
#!/usr/bin/env perl
use strict;
while (<DATA>) {
print; }
__DATA__
1
2
3
$ perl pseudo_file.pl
1
2
3
$ _
I would really like to be able to do something similar in a Bourne shell script where I don't have to manage a collateral text file which is prone to getting lost. Does anyone know if there is a similar construct in shell programming? I would have thought this feature was a remnant that Perl inherited from its shell programming roots, but searching on the Web has revealed nothing of consequence.
Is it possible "reset" all (X, GDM related) permissions/settings of one user? What would cause one specific user not to be able to log into anything via gdm/the login screen? After providing the proper password, the screen goes black and then jumps back to the login screen. No session alternative works, not even xterm or gnome failsafe. I can however log in via the console (Ctrl+Alt+F6, recovery etc). With another user I can log in via GDM just fine, and deleting and re-adding the "broken" user doesn't make any difference.
Some (maybe) relevent logs:
