General :: Shell Script To Automatically Login Through Ssh And Create User?
Oct 20, 2010
I was trying to create a shell script which will automatically login to the server 192.168.1.7 and checks if a user exists there or not, if it doesn't exist then it should create the user.I have very little idea about shell scriptThis is what I tried:Quote:
#!/bin/bash
pass="sacharje"
ssh 192.168.1.7
Now, how to pass that password automatically to the ssh when it asks for the password? (I can't use public key authentication here)

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.

yesterday I updated my fedora 13 to fedora 14 (on laptop) and today i cannot log in on user. It just go blank for a sec and is back to login.
At text console (alt+ctr+f2/f3) i enter my username and pass it give this for a sec and resets (clean) console
username: Name
password:
last used: [date]
login: no shell permission denied
i used unetbootin (fedora 14 netinstall to update) and later i updated 1,5G before reboot (did update that fix, forgot its name tho :s)
I would most likely reinstall everything, but i have some work at laptop and as death-line is near, i would prefer to fix it if possible.

I have a network set up that has been working for around a year with no problems but has now developed a login problem. The system was set up with a main server with all users on it and another PC located elsewhere that people could log onto using there personal login and password that then gained access to the account on the main server. This remote PC has now got the problem. When you try to log onto an account it comes up with the message "your session has lasted less than 10 seconds. If you have not logged out yourself this could mean there is a installation problem or that you are out of disk space."
Error message says that no profile for the user can be found and it couldnt create per-user gnome configuration directory. I can log on as root onto the remote PC as it is obviously a local account but all the account on the main server are not accessible. From the root account I can see that the connection to the server is OK and I can actually log into the accounts on the server using the failsafe session so the physical network is OK.
I never built or designed this set up and to be honest I normally work with windows so its all a bit strange to me. Both PC's run Centos 5. I have checked the messages log and there doesnt seem to be any indication of a problem. Just that it stopped connecting from the remote PC. The accounts are all active on the main server itself and have no problems being accessed.

I inadvertently typed the wrong path when changing my user login shell and now every time I log in I get a message stating that it can't find the shell and boots me off the system. It will then redisplay the login prompt. I'm running Ubuntu Server x64 in VMware Workstation.

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:
Code:
# 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:
Code:
...
anonymous_enable=NO
...
userlist_enable=YES
userlist_deny=NO
userlist_file=/etc/vsftpd/user_list
...
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:
Code:
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:
Code:
$ lftp localhost
lftp localhost:~> user install
Mot de passe :
[code]...

I've looked everywhere but I can't find where to change the default box for incoming mail, or am I on the wrong track. It's a nuisance having to change folders and I can't configure wastebin to empty on exit.And I can't get kmail to import from evolution. Do I have to go to the evolution storage and do it manually, and if so, how do I do that?

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"
code....

I've created a set of users using the newusers command. Unfortunatelly ive messed up and added all users to the 1000 group as primary group instead of giving the group argument as null what would add them to a new group. To make things clear:
The entries should be
user:password:::User Name:/home/user:/bin/bash
but I did
user:password::1000:User Name:/home/user:/bin/bash
I need to create the missing groups. A simple fix could be do a for loop creating a group with the name of each user in my file and then adding the users to it. Are there any dangers of doing it? What impact could this change have? Are there any safer ways?
A combination of the following commands:
Quote:
Add users to a group with the gpasswd command:
# gpasswd -a [user] [group]
To delete existing groups:
# groupdel [group]
To remove users from a group:
# gpasswd -d [user] [group]
If the user is currently logged in, he/she must log out and in again for the change to have effect.
Quote:
for i in (names)
do groupadd $i
gpasswd -a $i $i
Assuming I've created all users in group 1000 I could remove them from it with
Quote:
# gpasswd -d [user] [group]

I'm using openvpn under linux OS which is Fedora Core 14, in the folder "/etc/openvpn" i put 5 files which belongs to the network server that I should connect to, files are :
two files with the extension ".crt"
two files with the extension ".key"
one file with the extension ".conf"
Now, when I issue the following command (as root) :
Code:
/etc/init.d/openvpn start
It asks for my username & password to the network server, & after I entered the required authentication information, I successfully login, but I get disconnected automatically after two or three seconds.
- I connect to the network without any disconnection or problems under windows
- I use openvpn version "openvpn-2.1.1-2.fc13.i686"
- there was a bug in my OS "Fedora core 14" which is that I cannot activate or deactivate any ethernet cards, which solved by disabling NetworkManager in all run levels
- I disabled iptables
- I disabled selinux
- I got this error in /var/log/messages file when I disconnect from the openvpn network "
