General :: Login As Other User Using Shell Doesn't Load The Profile For That User?

Dec 11, 2009

I am using the sudo command to log on locally as another user by the following command:

sudo -u theotheruser -s
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.

Slackware :: VSFTPD User Versus Login Shell Definition

Jul 18, 2011

I'm using VSFTPD on my office LAN for one simple task: to receive-and send - installation images created with Ghost4Linux. Until recently, my main LAN server ran on CentOS, but I decided to migrate it to Slackware (nicer release policy ).

What I usually do is create an 'install' user who can login to FTP, but not on the system. Here's an example of what I used to do on my CentOS setup:


# mkdir -p -m 0700 /home/ftp/install
# groupadd install
# useradd -d /home/ftp/install -g install -s /sbin/nologin install
# chown -R install:install /home/ftp/install
# passwd install

The relevant bits in vsftpd.conf looked like this on the CentOS server:



Then I only had to create the /etc/vsftpd/user_list file and put a single line in it to allow the newly created user:


install Now I've tried to get the same behaviour on Slackware, and I succeeded more or less, except for one thing. There's no way my 'install' user can login to FTP when his default shell is set to '/sbin/nologin' (or '/bin/false'). Only when I change the 'install' users' default shell to a "real" shell like '/bin/bash', he's able to login.

Here's a little practical demonstration of what's happening:


$ lftp localhost
lftp localhost:~> user install
Mot de passe :

General :: Deleting Another User's Diretories From Own?

Apr 12, 2010

I am a non-root user, and have made a directory into which other users in my group can write. The directory is setgid, so files and directories within it have the same group.I can delete files placed into this directory, but if a user creates a subdirectory with files in it, I can't seem to delete those. Is there something special I can do (other than, say, bothering the user in question or the sysadmin about it) to get rid of this subdirectory?

EDIT: Inevitably, of course, someone asks "why?"The shared folder in question is a mercurial repository. We can't use a shared-account ssh-key-based server for this like mercurial-server, and we can't just host it externally for various reasons. But that part works fine.We use Redmine for project management, but it does not yet read the repo index for file contents - it reads the working directory. So the working directory must be kept up-to-datecrontab has been disabled by the sysadmin, so that's out. So I naïvely put a changeset hook in the shared repo that performed an "hg update". This seemed to work fine initially, until, of course, someone pushed a commit with a new directory. While I had vague thoughts of trying to make a setuid script for the hook, I'll probably just consider safer avenues.

General :: Login Shell And Consequent Subshells

Jun 13, 2010

When we are asked for password while booting Linux, is that the login shell ? If yes, we can't seem to be able to do anything in that shell besides typing the password. (Is it in this that the contents of /home/.profile file gets executed ? in a sigle PC)

When we click on the terminal icon for the first time, are we opening a subshell of something or a new shell altogether? If on repeatedly clicking on the terminal icon, new shells are being launched, not sub-shells, then why does export seem to work with the new shells, though its supposed to work for subshells ?

Code:- '-K': Allow users to resume and upload files, but *NOT* to delete or renamethemDirectories can be removed, but only if they are empty. However,overwriting existing files is still allowed (to support upload resume) . Ifyou want to disable this too, add -r (--autorename) .This is pretty much what I want to do, but I only want this done to ONE user on the server. I have many user accounts, but only one of them I want to prevent users from issuing the "delete" command and deleting everything.
