Ubuntu Networking :: SSH Adding A New Non-Local User?
Jan 5, 2011
Trying to add my wife as a user to my computer, only to log on through SSH, not locally. Only problem is I use keys for logging in.
I've gone through the guide on the ubuntu website, created a key, copied to through a pen drive, put it in her .ssh folder on my computer, but it still comes up with the error:
Code:
Agent admitted failure to sign using the key.
Permission denied (publickey).
Is there a group I need to add her to, or add her public key to a different file somewhere?

On Ubuntu, the local user is automatically added the xhost list when logging in (via a script in /etc/X11/Xsession.d).
Is there a way to enable this in OpenSUSE?
(My original problem is that I cannot interact with a running X session when loggin in via SSH, since newer GDM versions don't create $HOME/.Xauthority any longer.)

I have a Linux host connected via LAN to Internet. No proxy or squid is used on the host and outgoing traffic to Internet is not limited. I have several local users on this box. Recently bandwidth statistics on the switch/router showed increase in the Internet traffic from this host. How do I monitor the traffic utilization per local user on Linux host? I want to be able to monitor the amount of traffic per port and per user, like user alice downloaded 20GB today via port 22, and so on. Do not offer to use Squid, this is not just web traffic I want to monirot but all amount of incoming/outgoing traffic per user per port.

I'm trying to get vsftpd running with both anonymous and local user access to the same folder. The directory I'm using is /tftp with the following permissions:
dr-srwxrwx 7 root root 12288 2009-08-14 15:54 tftp
My vsftpd.conf is this:
anonymous_enable=YES
local_enable=YES
write_enable=YES
[code]....
I set the default "ftp" user's home directory to /tftp (was /var/ftp).

I am currently working on a project related to packet sniffing which has been implemented using the concept of raw sockets. I am using C language.I am able to decode the following details from the packets received from a local network,like:
source and Destination Mac Address
source and Destination IP Address
source and Destination port no
But I am having trouble in decoding the domain name when an user in the local network is logging onto internet.For eg. if a user in the local network is trying to log on to web using his browser say if he has logged on to url then from the packet I need to get the following details
source Mac Address from which user had logged on
source IP Address from which user had logged on
domain name

I have a Fedora 12 and OpenSuse DVD with me. It consists of lots of packages and hence to install these packages I don't have to download them. What I want to do is copy the package folder on my local machine and then add them as repository in Synaptic Packet Manager.

Take a physical user FRED. FRED is a linux user ( known by linux on his laptop ) FRED is a Samba user ( Known by samba on the samba pdc server ) When he logs locally (with username/password) on its standalone laptop (with no network), he is known as FRED:user. He access his data in /home/FRED/. When he logs through samba (with username/password) on the domain MY_DOM, he is known as MY_DOMFRED:MY_DOMdomain user. He access his data in /home/MY_DOM/FRED/. ) Is it possible that the human FRED has only one repository and have full access to its repository regardless of how it was connected. If yes, how to do it
2) If not, Is it possible that the human FRED has full access to /home/FRED/.............. and /home/MY_DOM/FRED/.

I have configured a CENTOS 5.5 server with DHCP + DNS. The network environment contains clients to obtain IP dynamically and some amy be configured manually. Until noe I have not used any GUIs for the configuration.
Now I want to manually add some hosts to my DNS. Can this be done by directly adding the host names to data files (pointed by the f/w and rev zones)? Or should this be done differently?
What are the good DNS GUI tools available for CentOS?

I've noticed that the root account $PATH does not include /usr/local/bin or /usr/local/sbin by default. Are there any potential issues that could arise from adding those directories to the path? If so, what is the best way to make sure your shell finds executables in those directories, without affecting the stability and security of the system?

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

How would you make NIS user information override local user information on client systems? This is what I think is right? Add nis on the passwd registration file on the second line Is this correct?

I've created a new user on the system and can login to the server with SFTP but can only add/remove files in the users folder and nowhere else on the server.
I've tried adding
AllowUsers username to sshd_config but that made no difference?

I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.
However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.
Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?

I recently re-installed my U10.04 and this time around, I added a root user and brought the permission levels of my default user to "Desktop User" as well as elevate the root permissions as explained elsewhere in these forums. Everything went fine until I wanted to "sudo" something from the Desktop User account terminal. I use Skype a lot and preferred to use the repos to get it loaded. Into synaptic where it asked me for the password. I entered the password and I was rejected. Ok, maybe I typed it in wrong. Tried again. The third time I checked in an editor to make sure I wasn't in all-caps. Third time OUT!
Switched user to root and there were no problems. Enabled the partner repos, installed Skype, as well as all the other stuff I use to run my home office. I have missed something, I know I have - perhaps a setting somewhere in the user permissions. I don't want to have to switch user every time I have to make changes to the system. Alternatively, if it's better practise to just leave my system as it is for security purposes I'm not running a server, but I'd like to have my system as secure as reasonably possible without elevating my problem to "paranoid security" level.......

CentOS 5.3
I have added a new user by doing the following:
useradd -m jobBlogs
It creates the home directory with initial files. However, when I do the following
ls -a
there is no .ssh directory.
Am I doing something incorrect here?

Im trying to create the following script...I want to create an interactive script that prompts the user for the following:
user name
user home directory
user login shell
user comment
the script then needs to read those variables that are entered by the user and actually create the user account. and of course, would like the script to display what user account was just created so that i know in fact the script worked successful.

I've been trying to add a user to the system, so I can use it through samba to access the shares on the server. I'm using "useradd" but the command is not found... with a little search, I was able to find the command "/usr/sbin/useradd username" my question is can someone point me to a guide with basic administration task, I was checking out the wiki on Centos, but didn't find "adding user"; I know Centos has a gui for this, but I would like to stick to shell commands. By the way why some commands are only access through /sbin and others /usr/sbin. I know this probably has to do with your path, but how can I fix this so I don't have to type the whole path every time.

I have Ubuntu 10.04.2 (Linux 2.6.32-33-server on x86_64) with OpenLDAP 2.4.21 and Webmin1.550. I converted my ldap database from another system with the older style schema (OpenLDAP 2.3.3 with slightly older Webmin version 1.480) and no longer use slapd.conf, but the newer slapd.d format.
It all works fine except for one thing. When I add a new user, it lets me type in the additional LDAP fields:
But when I click the Create button, all the fields get jumbled together in the Title/Position box with a diamond question mark delimiting the fields:
Modifying existing users (which have the Additional fields displaying correctly) also has the same result - it moves the fields all into the one Title/Position box with the diamond shapes with question marks inside between each entry. Is it a problem with my schema files? I tried reverting to the older shema files and slapd.conf and it still did the same thing on the new system. I am really at a loss.
Here is also the output of ldapsearch for that user (host and samba ids are sanitized):
Previously added users that show the fields properly have "description:" and then the field listed for each Additional LDAP field. Also shouldn't the "title" be visible in plain human readable text here? - it looks like it encrypted it somehow - similar to a password hash. The older system works fine and the fields are all readable and in their proper locations. But the new system just doesn't work right.
