Server :: Securing SSH Via Webmin ?
Jan 26, 2010
I installed OpenSSH via tasksel and am using Webmin for administration. I'd like to be able to SSH externally and want to setup the necessary public/private keys to use in FileZilla.
In Webmin, under Servers > SSH Server I can click 'Host Keys' and see an RSA key. Is this the public or private key for my server? Do I need to copy this into a text file to import it into FileZilla on my remote PC (that I want to connect from)? Is that all that needs to be done (aside from opening the port on my router/firewall)?
Is there an automated way to set this up via Webmin?

We have a public server and it can be accessed from any where through ssh.
My question is my server should not allow anyone directly to login as root user. First he should login as normal user then he should switch to root user.
I also have another questions is there any specific linux command is there to end other users ssh session without rebooting the server.

I am creating an FTP server using VSFTP. It will be in the wild, initially at least only functioning as an FTP server. I have the iptables config from the previous box I set up 3-4 years ago. I have also got private/public key authentication running with SSH to eliminate brute force attacks.
Here is where is my specific question. On the old server I set up something that allowed my clients to log in using accounts that were not system accounts but would translate to a single system account that was limited to FTP. I remember setting up a passwd account that had username / password pairs that FTP used for authentication.
What app is this? Is it just part of VSFTP or maybe SELInux? I really want to utilize this.

I have a blog on my site and am using htaccess rewrite rules to block all those nasty scripts from trying to execute various things mostly relating to phpmyadmin and wordpress. This has reduced my httpd error logs to less than half from before.
Am trying to come up with a rule to rewrite all calls to certain files if they are not originating from my domain, here is how it looks right now but it's not working as I can see scripts trying to hit "wp-comments-post.php" getting a 500 Internal Server Error.

I have an Ubuntu Lucid server that is public facing. I haven't really configured much on it except installing SSH (sshd) and Apache (httpd); I don't have a firewall or anything. Are there some common rules that I should follow to secure my system? I've been following this article on securing my Apache.

I'm running an SFPT server which my clients logon to using an FTP client. at the moment each client has a user name and password.
Thus far to improve security I've disabled root login but an looking for futrhrt ways to protect it from attack, having researched using google some of the security features suggested prevent the FPT clients from connecting.
Questions:
1- what further things can i do to secure my server that still allows it to be usable for FTP clients?
2- specifically is it possible to use non login pre-share key authentication?
How i set up the server is shown here: [url]

I have to deploy a server to some customers that should not be given access to the server itself. I know that nothing is 100% secure but I've searched without finding a decent answer (maybe I googled for the wrong terms ?)I need some advice about encrypted filesystem. * The server must boot without asking for a passphrase (the server will be in a restricted access area so typing a password could take a while). I can't store the password for luks in an unencrypted file so it seems a loop to me. The only way out I can see is to store the passphrase in the boot binaries (better than nothing...) but this results in more work for me.* possibly the customer should not be able to move the hard disks to another pc, i.e. reading the passphrase from some unique hardware ID. This is risky but I could add a master passphrase to be used in case of hardware replacement

We want to set up a Linux server (hosting Git or later SVN repositories) which should have all stored data strongly encrypted, so that if one steals the server the data cannot be read. For example, our notebooks have all important data stored on a "true-crypted" partition.
We plan to access it with SSH private keys and only after successful login should the data be readable. The server would be located in our office, shut down at night and not be connected to the Internet directly, but only accessible in our intranet.

I have had webmin running previously but i just recently installed Unbuntu server and i am now trying to install webmin. after typing this to install webmin sudo apt-get install webmin it started doing its thing and then it halts.
Giving me the following message: "Package webmin is not available, but is referred to by another package. this may mean that the package is missing, had been obsoleted , or is only available from another source."
The first thing i did after installing webmin was edit the sources.list
Then i tpyed sudo nano sources.list I uncommented everything with "deb" in front of it
I also uncommented
deb cdrom:
I then typed this sudo wget [url]
After getting that i typed this apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
Then i tryed to install it and got that error.
I also tryed install it using this tutorial [url]
When i got to the part when i need to type
sudo apt-get install update this is what happened

I encountered a a dependency issue when trying to install Webmin on Ubuntu Server Edition 10.04 Beta1.
When you try to install webmin, libmd5-perl is not available in any of the lucid repositories:
I resolved the dependency prob by adding the following repository to my /etc/apt/sources.list: deb [url]
Then I did a sudo apt-get update then sudo apt-get install and libmd5-perl installed fine along with webadmin. BTW. I got a GPG error when doing a apt=get update because I did not import the public key for the debian repos I used to get libdm5-perl, which doesn't matter to me as I commented out the repos once I got libmd5-perl installed.

I recently installed Ubuntu server 9.04. It appears to be functioning correctly in that I can acces it from other Windows machines ony my network. I installed Webmin to remotely administer this server, however I cannot connect using Webmin from my other machines. I am only running Samba on this server at the present time.
I attempted to access the webmin conf file at /etc/webmin/miniserv.conf but permission wasa denied, evenas root.

To make my problem simple to understand I've attached a picture. Basically, in the Webmin>Apache configuration page, where I used to also enable/disable the modules Apache was using (on Ubuntu 8.04) I've noticed now that the option to configure the modules is no more (on Centos 5). So, I'd like to disable and enable some modules but can't, like the mod_python for example which gives me hundreds of errors in the Apache's logs, but cannot.
how to view the Apache modules again in Webmin?
just noticed can't attach images... here's the link to the picture: [URL]

I have a computer running Ubuntu 10.04. I have installed Webmin on it and everything is working fine except for the GRUB module. I wish to know if there is a new GRUB module that supports GRUB 2? It may be beta or an unofficial one.

I'm a newbie here but I have a question on how to make the connection between webmin and thunderbird via POP3. I have webmin set up and it is able to send and receive mail via webmin but when I enter the account details in thunderbird it cant find the settings for my mail account. I'm not exactly sure where I need to go in webmin to set it up to allow a connection from a client to allow the downloading of mail to the client. Would simply prefer to go to thunderbird to send and receive mail as opposed to logging into webmin then going to my mail.

I have webmin on my linux server, I've made a cron job which requires a password to be entered after the command has been run.. all good. I noticed the cron job has the option "Input to command", where after many hours googling a can assume this is where you type input after the cron job has run (for example, a password?). I have tired putting the password needed for the job (the cron job is an ssh root@address) into this field however the output when running the cronjob is saying "permision denied" still.
Is there some sort of character I have to enter in this field, like
-p mypassword:
or
*mypassword?
or
"mypassword"

I want to install Webmin on a dedicated remote server. I keep reading different blogs/tutorials etc about installing webmin on Ubunto server 10.10 but it seems too easy to be true. There is never any mention of requirements etc. I did read that even perl isn't needed pre install now and will install with webmin.But do i need to install lamp etc first or does it pull these in when Webmin its installed?

I have a dummy server set up in which I am trying to install webmin (which I have done several times in the past and remb it being straightforward and pretty simple!) however when trying to install I keep getting errors.
I install all the perl packages as required :-
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
After downloading webmin I try and install it:-
sudo dpkg -i webmin_ 1.530 _all.deb
This is where I encounter errors regarding apt-show-versions saying that it is not installed.I try and install it but an error appears stating that apt-show-versions is not installed. So I try and install apt-show-versions and that fails as it states that there is libapt package missing too. When I try to force install both - unable to fetch some archives but maybe run apt-get update or fix missing....It just seems like I am going around in circles (as I have run apt-get update and have run the commands as root...)

I installed webmin on Debian apt-get install webmin. After installation following message came.
Code:
Setting up webmin (1.510-2) ...
Webmin install complete. You can now login to https://IP:10000/
as root with your root password, or as any user who can use sudo to run commands as root. So I infer that the installation was successful.
But when I do
Code:
http://IP:10000
I get following error
Code:
Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED): Unknown error.
