What are the differences between "su -" in a GUI terminal and directly logging in as root in a text mode terminal (tty1-tty6)? Any environment, path or other functionality differences?
View 14 RepliesI'm using squeeze. I wanted to know how you could determine from the command line in tty1 (or tty2 through tty6) what the resolution was that text was being displayed at. Is there a way? I know that in grub, you're supposed to be able to go to the command line and type vbeinfo. I tried this and got some information, but somehow I think it doesn't always apply to the terminal after the computer has booted up.

Ok i start to find it boring to ALT+CTRL+F1 each time i want that when i boot it directly go to tty 1. But i also want it to load desktop environment, but not to show it, only load it, so if i ALT+CTRL+F7, it goes to desktop environment. If its not loaded, it will not go to desktop environment or it will take like 15 sec to load it, this is why i want to load it while i am in the terminal.Also, how can i switch resolution in terminal?
View 3 Replies View RelatedI have a server laptop sitting around at home which is a pretty bland server, on which I generally leave the lid open and there is a login prompt always displayed.
However, I'd love to be able to display useful information on /dev/tty1 so whilst the server is just sitting there, rather than displaying a login prompt on the monitor, it could now display, for example, the current time and weather forecast for the day. Or something along those lines.
I've been installing proftpd on a server running fedora 8. It is setup in standalone server type, and I checked that the process is running and listening to port 21.
When I try to login using a ftp client in Normal mode with root user & password , I receive first a 220, then a 530 login incorrect error.
Can you help me?
I've been pasting my proftpd.conf configuration file below
Code:
My terminal text is unreadable. Where as the default output would usually fill half the screen it probably fills around 1/20th now. Basically it looks like the text is 1px in size. I was about to install a graphics driver (nvidia) but doh I can't see what I'm typing... I can't start gdm even after memorising the process of logging in and starting gdm (I think gdm is failing to start anyway) I'm using the default xorg.conf provided with the LiveCD;

View 2 Replies View RelatedEveryone is wondering why we can't run gEdit and other tools from a terminal by logging in as root(e.g"su-"), I understand that by making changes they are trying to force us as users of Linux to learn better habits that are more secure, but the issues are driving people nuts!
I for one really like being able to log as root and open gEdit to make drive changes without having to login as root, I would normally still have access to all my things like email etc. So changing Linux to force everyone to not use tools like gEdit as root is becoming more of an inconvenience than they realize, there must be a safe way to do this!

I can login as root in to Gnome and ssh but not in the console In fact I can login with anyuser in to Gnome and ssh but not in the console. By the console I'm referring to tty1-tty6.

I also looked the file /etc/securetty and this is the content:

I even can use "su" with root with no problem. The next entries are written in the /var/log/audit/audit.log file everytime I has this error:

View 2 Replies View RelatedI installed Centos 5.4 on my Pentium E5300 new comp, but I need IPX support in my work. It's simple - ipxutils and ncpfs from Fedora Core and new kernel with ipx support. I copied kernel config from /boot folder and activate ipx, ntfs support, and choose processor core 2 duo. New kernel (2.6.26) works OK, but I got one problem - when start it still shows message: "kernel: HUB 1.0:1.0 unable to enumerate USB device on port 1 (or 2, 3)" and stops after logging (text mode)
I got 2 USB devices connected - printer HP D5160 PhotoSmart and Scanner A3 USB Mustek, and I know scanner cause that messages but I don't understand why. Kernel config is the same like that from distro kernel (almost - ipx, ntfs and proc), but distro kernel doesn't do that. So I got 2 questions:
1. Why
2. What to do to stop that (disconnecting devices on boot time is not a solution)

View 5 Replies View RelatedI 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?

View 8 Replies View RelatedI tried most methods suggested on many sites to install drivers
## through the additional driver panel only
## through the Nvidia.run file I downloaded
## through the terminal using apt-get
All failed to start ubuntu gui it takes me to the console login and I noticed it says "saned disabled" edit /etc/..something. This problem made me install ubuntu again three times and every time I activate the driver then install the driver Nvidia.run or through apt-get and both leads to a black screen tty1 login. So what to do now I installed and removed many things and I won't reinstall ubuntu again. Also I typed compiz and this came on:

A new and very exciting error everyone now also the windows 7 that I have besides linux has also crashed and cannot open the login window. I don't know whats happening all I know is that few hours ago I logged in to windows normally now I cannot login to either one of them and the funny part is: I'm working on my thesis on this computer and I cannot work anymore and I'm supposed to meet with the professor on monday.
Finished installing Ubuntu 10.10 in my XPS15, intel i5 4g ram, nvidia GT 420M graphics card,
problem is when i go to additional drivers, the driver listed (Nvidia accelerated graphics) when I install it and reboot it the computer starts on the terminal, no graphic interface. All I get is the black screen asking me login and password, when I enter them, just get the terminal prompt in a black screen.
I am pondering on what would be any implications in logging in via SSH as root?Surely SSH is safe or am I kidding myself and falling for the unwary ethic of logging into a remote Linux box as root?I discovered some open ports remotely on the linux box, and decided to login as root to edit a configuration file to shut off the ports, hence my questioning in whether logging in as root...another point, since SSH is 'supposedly secure', there should not be any implications or am I kidding myself!??? Would it be better to login as normal user then su from there?
Ok, to make things even more interesting, what if its a bog standard generic linux distribution with no suid programs etc, then what happens...take that out of the picture, and say, for editing a configuration file...hackers are not going to see that are they, otherwise by the sound of the answers, it is putting an impression that hackers can see the traffic the minute you login as root?! Otherwise why bother using SSH? I mean, surely, SSH was designed to replace telnet and thereby increase protection...as we all know back in the early 90's before the internet became publicly available, that there was indeed sysadmins dialing in to private networks or telnet'ting into a remote system as root....
I bought an imac G3 yesterday and it has xubuntu 6.06 Dapper Drake installed on it. When i turn it on, after it POSTs, a little xubuntu logo appears it it begins to load 'essential drivers' and mount the file system, etc. After it is done doing that, it simply prompts me into a CLI that on the top says "Ubuntu 6.06.1 LTS ubuntu tty1". It asks for my username and password, and then it just keeps me in this tty1 terminal. I did some research online and supposedly by pressing alt+F7 you can exit the tty terminals and go back into GUI mode. Well pressing alt+F7 does nothing, and pressing alt+F1 through 6 just sends me into the different tty terminals.
I am very new to Linux so if someone could give me an idiot proof explanation on either how to fix it or whether im screwed and just need to reinstall xubuntu on here.

View 2 Replies View RelatedI have created a linux machine and installed some softwares on it with root user privileges . I used to login with root user credentials for doing the various task.
Later i have realise that this is not the best practice to follow and there should be a new user with less privileges to be created for doing the day to day task.
I have read the steps to create the user but will that new user sufficient enough to do the task that i m doing it through root user?
Will my software allow the new user to work on them?
I would be glad if someone points me to a guidelines on what should be my next step?
This must've been done before: I want to keep a log file open in terminal so I can monitor updates to it as they occur. My searches are coming up with everything but this situation... I must be missing some terminology or something key, because people do this all the time inside of other programs (NetBeans, or rails server, for example).
