I installed SSH-keygen dependancies for a /chroot user.

I have been reading through the linux guide as the bash tutorial said i should before learning bash.
The Guide told me i shouldnt use the administrator account as my everyday account so i added a new user but the network manager doesnt show and i cannot connect to my wireless internet. I have approved the secondary account to access the net and everything but i cant figure this out.
If user1's main group is genetics and one wants to add him/her to group biochem and to assign biochem as his/her secondary group will the following suffice ?
Code:
$ sudo usermod -G biochem user1
I would like for user1 to have genetics as the main group but also belong to biochem. When user1 creates a file, as he/she belongs to main group genetics, I assume the file will be owned by user1 and group owner will be genetics. Ideally files created by user1 should be accessible to users in group genetics(when permissions are tweaked) but not by individuals in group biochem. However, any files with group owner biochem should be accessible to user1 as he/she does belong to biochem as a secondary group. Would having user1 main group genetics, secondary group biochem fulfil this criteria ?
I run both Mac OS X and Lucid. I backed up my OS X partition in preparation for a restore. I also moved over important work documents to Lucid. Restored OS X using timemachine. Updated OS X with patches and moved over some files from external hard drive. After moving the files over, timemachine backed up system. I went into Time machine to transfer work documents over but the previous back up was deleted for the new one. I had the documents on Lucid. I just needed to switch it over to OS X. Therefore, I tried to enable read/write from Lucid to Mac OS X partition.
1. sudo usermod -u osx-uid ubuntu-username # change Ubuntu UID to 501
2. sudo umount /osx # UNMOUNT OSX PARTITION FIRST!!!
3. sudo find / -uid old-ubuntu-uid -print0 | xargs -0 chown osx-uid # change file permissions
OS X was unmounted prior to entering commands and performed the steps above under a different user. During step 3 I received an error stating you do not have sufficient privileges and the process stopped. I logged out of my temporary account and tried logging back into my main account. Main account was not present on the login screen. So I followed these steps to change my UID and GID from 501 back to 1000. Login appeared. I tried to login but there was an error about ICEauthority and Nautilus. System doesn't load up and only shows wallpaper. I haven't deleted anything and I expect that I just need to point my UID back to wherever my home folder is.
I have an issue in my organisation that a particular user X's mail not able to forward from my linux server MTA postfix to my second windows exchange (HUB)mail server. We use linux mail server as SMTP Gateway we have implemented fetchmail for doing this job. and its MTA is postfix OS is SUSE. Rest users mail are able to come in exchange HUB server via linux mail server. When I see that purticular user X mail in linux I am able see its spool file in /var/spool/mail and also via mail or mutt command. My question is why postix not able to forward that user X mail to our exchange HUB server.

I can't get a program (wbar) to run directly from my user account, it fails saying "Image not found -> maybe using a relative path?". But if I run su -c "wbar", it shows up and manages to load the image. I think it has something to do with ImLib2 or whatever loads the image. I checked permissions on libImlib2.so.1 and it's world-readable and executable. Can libImlib2.a be causing this problem, set to 644? What else should I be checking?
View 2 Replies View RelatedI've run into a strange problem with GDM that I haven't managed to find a solution for yet, either by trying myself or googling, and I have run out of good ideas. I'll just infodump here about the problem and what I've tried etc;
I installed Ubuntu on a new PC a few weeks ago, setting it up with autologin for my mom and a separate user for myself, using the on/off-icon menu in the top-right corner to switch to my own user and back as needed, and logging the user out when done. This worked quite well.
However, a few days ago, this stopped working; logging out or trying to switch now leaves me with a blank black screen, without even a mouse pointer (but not off, the backlight is on).
EDIT: To clarify, this is an issue that only affects the GDM login screen, but that affects it whenever it is used, wether it is on boot (when not set to autologin), after logging out, or when trying to switch user.
At this point, I can usually use Ctrl-Alt-F1 to get a textmode login, and Ctrl-Alt-F7 to get back to the auto-logged in session (assuming I tried to switch, not logout).
I can't think of anything specific I did or installed around then that should be related in any way...
I tried disabling autologin and restarting gdm, which left me with the same black screen (which is still there after rebooting), instead of the expected login window. I managed to re-enable autologin by manually editing the /etc/gdm/custom.conf file, so that it would at least work for mom.
I've also tried to change which user is auto-logged in, thinking it might be a problem with my user account, but both users get an automatic session just fine when I restart gdm.
I thought it might be a problem with the video driver, but that's not the case - if I run zenity --info as root with DISPLAY set correctly, the dialog box appears on the screen just fine. It has no borders or titlebar (there's no windowmanager), and is apparently without keyboard focus, so since there's no visible mouse pointer I can't click the OK button... But since it appears, X is apparently up and running just fine, just has nothing to display other than a black background.
I tried purging and reinstalling gdm and gnome-session(-bin|-common), but that didn't help any.
Running ck-list-sessions after trying to switch indicates that there's a new session there, with session-type = 'LoginWindow', so it appears to think everything's fine.
Enabling debug output in the /etc/gdm/custom.conf file did get me some more debug output in the gdm logs, but it didn't really tell me anything, there weren't any obvious problems that I could see.
After some looking around, I've guessed that it's supposed to be running gdm-simple-greeter, which I assume would display a login box; trying to run it manually doesn't work though (it's missing some environment variables, and trying to add them based on the abovementioned debug output doesn't really help).
I have a very strange problem.ometimes, yes sometimes not all the time, I get a Destination Host Unreachable when I ping a computer on my network. If I switch to root using su I can ping that same computer. Here is a screen shot:

i have sudo priveleges and can install via update manager. i read somewhere that compizfusion might affect access permissions and i do use compiz and emerald at the same time.
Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code:
su [insert username of old account without brackets]
sudo usermod -G admin [username of new admin account without brackets]
exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code:
su [insert username of old account without brackets]
Means were going to Switch User to the old admin account
Code:
sudo usermod -G admin [username of new admin account without brackets]
This simply adds the admin group to the secondary group list for the new user
Code:
exit
Pretty self explanatory
I wanted to create an user but don't allow it to see the other user's home folder so I made chmod 0750 /home/folder and it worked fine so I went ahead and decided to completely forbid access to the root folder and I had the "great" idea to make chmod 0750 /, and now I'm having problems with wine and other applications, in example I used to have a folder in this address 209.239.114.51/mmgr but now it's giving me errors and if I try to run some applications I got error "There was an error creating the child process for this terminal"
