Ubuntu Security :: Viability Of Running SSH On Default Port Using Key Auth?
Mar 8, 2010I don't think it would be harmful to run ssh on the default port of 22. Especially since the machine will only accept key-based logins and only accept traffic on port 22 from external IP addresses that I specify.

Ubuntu Servers :: Ssh Restart Gives Error In Auth.log
Oct 29, 2010When ever I restart ssh

Ubuntu Servers :: AD Auth - Changing Password At Logon
Nov 17, 2010I have succesfully set up authentication manually in Ubuntu so users can log on with Windows Active Directory accounts and have their network drives mapped automatically using pam_mount.
Please note due to the setup I can't make any changes to the Windows 2k3 server.
If a user wants their password reset I can change it to a generic password. When they next log on to a Windows computer with the generic password it will automatically ask them to change it to something else.
Is there anyway to get this to work with Ubuntu 10.10? At the moment when logging onto Ubuntu with an account that is in this state the message Please change your password appears, it then proceds to log on without prompting to change the password and natually it won't map the drives etc.
Ubuntu Servers :: No Servers Work Unless Logged In?
Feb 5, 2011I have the system setup and working, but I want to put it in a corner and forget about it. Problem is, nothing starts running unless I'm logged in. And if I log out, everything stops again.It's running a LAMP server and has VNC and SSH servers as well. I want all of that to start without having to log in. That way I can remote reboot without worries and connect and login with either VNC or SSH.Everything seems to have an entry in /etc/init.dIs the way it's acting normal behavior? It's a fresh install, then I installed everything I needed from the repos.
View 7 Replies View RelatedFedora Servers :: Force Php Mail() Through Postfix + Auth?
Mar 8, 2011I'm a bit lost with the PHP/Sendmail configuration, maybe somebody could help me getting back on the right track. Following situation:
Postfix:
* accepts smtp on port 25 but from his own domains. Some policy and spamchecks through amavisd are made.
* accepts submission on port 587 and 465 from authenticated users only. Quota and spamchecks prevent outgoing spam.
So I'm enforcing a very strong outgoing spam-policy but the users are still able to use the php mail() function to send spam through the /usr/sbin/sendmail command.
My users have access to their own php.ini so my idea was to somehow enforce the delivery through the local postfix on port 587 or 465 and just let them enter their user/pass in their php.ini. (I suppose, their might be a cleaner-solution ).
Unfortunately, my configurations like smtp_host, port, user etc. are getting ignored if the sendmail_path line is active. But if I comment this line out, php just uses the default, which is the same as configured in the sendmail_path line - so it's active whether i use the line or not (setting it to an invalid command breaks the mail() function completely).
how can I enforce my anti-spam policy on the php mail() command?For my ssh users I just blocked the outgoing connection to localhost on port 25 which seems to work so far, but somehow the postfix-sendmail-wrapper just ignores this.
Fedora Servers :: Config A Customer's Samba To Use A MS 2003 SBS For Auth

Currently the samba is config'ed for auth = Users. But I want a central point for user auth, and since they already have the sbs in place, I'd like to use that.

Ubuntu Servers :: Use F12 To Execute Script Even When Not Logged On
May 28, 2010how to bind a script to a F key (F12) that will run as root even when not logged in. I have a headless server on client premises where it'd be easier for them to press F12 to run this script that will be rarely needed than to give them SSH instructions etc. I know this must be do-able, but I can't get my Google-fu on for this question. The only way that I can possibly think of doing it is to touch a file whenever that key is pressed and have the script idly checking for that file every few seconds in a loop.

Feb 1, 2011I'm a total Linux noob, but I've needed a working development server for a while so I've put together an old celeron box running Ubuntu Server 10.10.The box runs fine, as does the Apache and MySQL servers, even if they did take a little while to fine tune!The problem I have is that vsftpd doesn't respond unless I'm logged on locally or via putty. As long as a local user is logged in, it's fine. If I try to connect when noone is logged in, then the connection times out waiting for the server message, and thereafter I have to login and stop / restart the vsftpd to make it work again.I'm not sure if the vsftpd is set to run on boot or on login and I have no idea how to check. Vsftpd is set to allow only local users, of which there is only one - so I can't check if it would work with any user logged in

View 2 Replies View RelatedFedora Servers :: Script Can't Access Mounted Location While Logged Out
Feb 24, 2011I want to backup some data on my Fedora box to a external Hard Disk (USB). I mounted the external HD on my box. I wrote a bash script to do that and I scheduled a cronjob to execute the script. When I am online the script executes as planned. However when I am logged out the copy does not work. I also tested this with a cifs mount (via fstab) and that does not work either. I set the script to generate some output at the end and that is OK so the script does run when I am offline. I suppose the mounted locations are not reachable while logged out, is that correct? Is there a workaround so I can reach the mounted locations while logged out?

Ubuntu Servers :: PhpMyAdmin Installation - Don't Use "sudo" Because Logged In As Root
Nov 25, 2010I'm trying to install phpMyAdmin on my Ubuntu 10.10 server. I type the following command (I don't use "sudo" because I'm logged in as root, I know its not safe):
Quote: apt-get install phpmyadmin and go through the installation. I allow the installation to configure the database, and I chose the correct server (Apache2), when it asks for passwords, I use the same password that I use for the rest of the server (i.e. it is the account password for root, sudo, and my account). Once the installation is complete, I try and access it from a computer on the same network. I type "http://***.***.*.*/phpmyadmin" and I get the message saying the directory isn't there. I go into Webmin to confirm that the directory isn't there, and it isn't.
My questions are (1) Why isn't the phpmyadmin directory in my Apache Server root? (2) Is it installed with apt-get, if so, where? (3) How do I know what server I selected for it to install to? (4) What do I need to do to get it to install correctly?
Ubuntu Servers :: Every Time Logged In Via SSH Got A Message Telling There Where Packages To Update Including A Security Update?
Feb 11, 2011I was running 10.04 LTS and had decided to stick to the LTS versions as I'm now running my machine as a server and don't want to be updating regularly.Every time I logged in via SSH I got a message telling me there where packages to update including a security update. So I did a search to find out how to perform an update on Ubuntu server from the command line.What I found was to do this:sudo apt-get updatesudo apt-get dist-upgradeAfter doing that I rebooted but now my machine gives me this message:
init: ureadahead-other main process (794) terminated with status 4Your disk drives are being checked for errors, this may take some timePress C to cancel all checks currently inprogressI'm not pressing C yet and leaving it alone to finish, but I noticed when the machine booted that one of the options for booting talked about Ubuntu 10.10, so I'm worried that I've updated from 10.04 LTS to 10.10 by accident?
Ubuntu Servers :: VNC To Ubuntu Server When Not Logged In?
Jul 28, 2010but I have a few Ubuntu server's that are Headless, and rather than walking to the server room with a display i thought, id rather push for a good challenge..So I would like to know how to remotely login to these Server's Desktop environments. not necessarily with more than one user at a time. just need to login to the machine's via VNC or RDC preferably VNC I do my admin work with Apple Remote Desktop. but I have RDC as well..
I set these systems up for my IT Department... and I need them to be super easy to access for the rest of my team. ( I am the only one aside from or Director privy to using the command line ) so in order to make it possible for normal humansI'm installing the desktop enjoyment on each of them now. but..From what I have found in my previous Linux adventures - it is not possible to VNC to system that is not already logged in, in other words if the machine is booted, but at the login window.. I have never been able to connect via VNC, I am only able to do this once the machine is physically logged in to it's desktop nvironment once that has happened I am able to connect with VNC, but,, something tells me this is possible - this is something I do on a regular basis with my OSX server's - and with RDC to manage my active directory server

canyouseeme.org says "Success: I can see your service on port (25565)"

Jan 20, 2010I have a virtual server setup on port 80 that works fine, however, if I change the port to, say, 8080 the browser then fails to connect.I'm using webmin to configure everything, all the other settings seem to work as I would expect.I get the error "Safari canī open the page http://192.168.0.12:8080 because Safari cant connect to the server 192.168.0.1." in safari, and i get something similar on the xubuntu machine in firefox connecting via localhost.It's almost as though theres a firewall in the way, but I think it's more likely to be some config problem.

View 9 Replies View RelatedUbuntu Servers :: Ssh Is Running But Port 22 Not Open
Jul 10, 2010I have two computers on a LAN. (This is history not a Bazaar question, although I have one of those too) One of them (Ubuntu 9.04) Im using as a Bazaar repository over sftp. Its been working fine for about a year. Then we had a thunderstorm that knocked out our Internet service for a couple of days. When it came back up everything is working fine accept I could no longer commit to the server. A little detective work showed that ssh was not running on the server. I started it and Bazaar then couldnt find the repository files. I still suspected an ssh problem, but port scans from both computers showed port 22 open on the server and I could do a ssh login from the client ok. Then I started fiddling with ssh on the server and now I have ssh problems on top of the Bazaar problems.
On the server I deleted then regenerated the ssh keys. Ive done
sudo /etc/init.d/ssh reload
sudo /etc/init.d/ssh start
I get a normal starting message and ps ef |grep ssh
shows /usr/sbin/sshd running. But the port scan does not show 22 open and I get connection refused at the client.
