Is there a program already set up to do this? Probably similar to WASTE (URL...), though waste's client is currently unsupported on the newest version of ubuntu (make error having to do with char* or something). Preferably windows and linux supported. Another thing that could be of use would be a local ssh chat. For example someone connects to my box either as me or as another user and runs 'hiben' and a window (or i ran a command or something and have a window open for it) pops up that we can chat in. Something other than single line messages.
I have been assigned a task to implement a free open source content filter having feature of web, email, instant messaging etc. If any one has the information or worked on this type of product please share it.
I booted up my laptop as usual and found that when I opened Empathy IM Client it would not allow me to login when I changed the status to Online (or equivalent). Normally as soon as I open the client the Messaging Status can be changed in the top right next to the clock so I tried to remove it but unfortunately it took the shut down panel with it.
To try and bring them back I used the restore panel commands in terminal:
I'm a Linux newbie and for my new job I have to do a lot of instant messaging to clients. They are on a variety of services, aim, icq, msn, myspace, facebook, yahoo, Google Talk, jabber, and .mac/ichat Is there a good instant messaging client that covers most of these on one application? I am using Mandriva with KDE 4.2.
I'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.
Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.
I seem to be missing a secure.log or security.log file. I have Ubuntu 10.04 and can't find this file. I looked in the /var/log and ran a search command to no avail. Does anyone know where this file is or is it called something else. I'm looking for a file that logs any change to the security settings of the system.
I set up my ubuntu server with iptables that only allows ssh in the input chain (and of course established connections) with only the mac adress of my laptop allowed to connect, set up a key with a long passphrase and installed pam_abl plugin. ICMP echo is blocked by default.
The only problem is i log all other attempts to connect to the server and i see a lot of traffic going to ports 445 and 5900.
My question is: Is there a possibility that these attempts could succeed and is there any way to further ensure this server?
Newbie here, I'm thinking of moving mostly to linux to get away from the security holes in Windows. And I have some questions...
How secure is Firefox for doing online banking?
Sometimes I have run into a situation where the bank doesn't support anything but Windows explorer when accessing my accounts. Can this be gotten around safely in Linux?
Is there any way to secure harddisk accessbility ? i want encrypt my hard disk, and partitions that ubuntu installed on that. is there a way ? i want deny all access to hard disk, just my own root account can have access to all.
Ok im new, i know apparmor is running. i was looking for firestarter but their isnt one.....how do i secure this server? i want a good firewall and some virus protection!. also do i need this?
I want to set up a website that hosts very confidential business information. The info needs to be accessed by multiple people in different geographical regions. The entire website would require the high security (ie: there are no little sections that are publicly viewable). While the site will be run with Ubuntu server, I will be hosting it in Amazon's EC2 cloud.
So, if I use the HTTPS protocol with an SSL certificate, am I pretty well reaching the most secure possible situation? Are there any concerns with using the EC2 solution? Obviously there are a LOT of variables involved with maintaining website security, but I want to know if HTTPS is the current best bet (in addition to all the "best practices" of securing a site) or if there is a more robust way of securing content.
I am running UFW, which is set to deny everything but SSH on port 22, OpenVPN on port 1194 and HTTPS on port 443. SSH is set to only allow private key logins, and the root account is disabled. I have AppArmor running for all of my daemons (OpenVPN, Apache2, OpenSSH) and I have Fail2Ban running.
Is there anything else I can do to secure my server from the Internet (it is directly connected, there is no NAT between the Internet and my server).
If I need to get a file to someone I could place it on the server and somehow automate an email telling them there is a file available. They could login to the server based on their email address and a randomly generated key combination and down load the file.I also need it to preform the same function going the other way. Login into my server and place files going to me.

I always hear 'do NOT install anything from anywhere except the official repositories'. But I find a lot of great apps that are not included in repositories and would like to ask. How actually secure launchpad is? Are the codes reviewed by anyone? How do I make sure that a piece of software is not going to harm my Ubuntu? If I add a PPA for some program I won't going to check it's code every time it updates or am I being too cautious?
Is there a way to securely empty the trash bin without the need to type some shred command into consoles. My intentions is to be able to securely delete files when the 'Empty Trash' is used so to save the trouble of going to a console and doing some commands using shred.
A friend of mine has a private forum setup so he and I can communicate back and forth so we don't have to send emails. The link is a "https://" so I'm assuming it's secure. I'm a newbie to ubuntu and I have already switch 3 of my computers at home to ubuntu.
I'm using Ubuntu 10.04 and google chrome as my browser. When I log into his forum it pops up with a screen saying "The site's security certificate is not trusted" and I always click proceed anyways. I'm not worried about this because I'm 110% sure that it's his website that I'm trying to access. My question/problem is it also pops up with a little box telling me to enter my Username and Password every time. When I was using WindowsXP, I had to enter this info once and then I wouldn't have to enter it again.
I recently installed Xubuntu on a 5+ year-old Acer Aspire laptop. In spite of how the root, swap and home are volumes in an LVM2 group on top of a fully-encrypted harddisk, it's quite swift this computer isn't for me, however; it's for my old man. It's been my pet project for the past few weeks, as an exercise in making Linux both highly secure and user-friendly, so that even a technophobe like him could use it without fear of identity theft if it ever gets lost or stolen. I recently shipped it off to him...
The weakest part of security, however, I fear may be the screensaver, which is why I ask. I've searched and searched and cannot manage to find any information on security hardening practices (apart from banal advice such as "always choose a secure password" and "never log in to an X-session as root"). What I want to know is, just how safe is a locked screen? Also...is it technically possible with the right tools to get a core dump of a running computer and thus extract the block device encryption key from memory? I know that your run-of-the-mill thief will just try hitting the power button and throwing in a livedisk, but hey, you never know. Edit: found. [URL] I guess I need to tell him how to set the BIOS password to thwart that sort of thing next time I talk to him on the phone...
I have a minecraft server running on a P4 box running Ubuntu server 11.04 64bit. Now would it be secure, if I allowed ufw to allow outgoing? Or would this be a huge flaw someone could exploit?

Is an ubuntu live cd totally secure from intrusion? Stated another way, even if someone knows my ip address, can the live cd environment be hacked into in any way so that another could monitor what I am doing on my computer? From my understanding the live cd is read only, so that would prevent anything malicious being installed on it. I am curious if there are other ways a box running a live cd could be tapped into.
