View 5 Replies View RelatedSecurity :: Iptables: Verify Traffic On Port To Check If It Is Legitimate For That Port?
Apr 18, 2011Is there any way to verify if packets being trafficked over a certain port are valid for the service you want to use this port for?
One obvious example that probably clarifies my question:
When I open port 443 (outgoing or incoming) for https/ssl traffic, I don't want this port to be used for say openvpn traffic.
Thus: when someone wants to surf to a website with https, it should be ok but if someone wants to connect to his home openvpn server over that same port, it should be blocked.
Security :: Port-bind Shellcodes Work With Port-forwarding?

View 2 Replies View RelatedUbuntu Security :: Router - Port Forwarding And Network Security
Nov 11, 2010As it stands I have a small home network operating behind my modem/router. Some of the ports on this are forwarded to my PS3 for gaming but I was looking at forward some for my file server.
At the moment I've forwarded port xxx22 to port 22 on my server for SSH for instance. ANd similarly 21 for FTP (although it doesnt seem to want to connect for any more than a few seconds using that). What I was thinking of doing was placing a small website for a handful of ppl to use on the server too and port forward again - xxx80 to 80. It works just fine but I'm a little concerned on the security front.
As I've moved the port to something different from the outside world I'm presuming I will have already cut the potential for malicious folks to wander in but is there anything else I should be doing? At the moment there's no firewall operating on the server, usually as its hidden behind the modem/router. But if I open this thign up more permanently what should I be doing? I've read a few articles on it but I'm always left with the overwhelming thought of "Thats if theres no firewall in my router" as they just seem to do the same.

Mar 1, 2010I'm disgusted with myself for not knowing the answer to this one, as I consider myself a fairly low-level hackerly type, but: How do I disable the USB port on a machine? This is so that if a pendrive is stuck into it, nothing will happen, i.e. no viruses which can attack the machine etc. The guy I know who wants this has WINDOZE machines on which he wants this done, but anyway I plan to migrate his office to Linux, after which I'd be wanting the above functionality.

Jul 18, 2011I'm running Fedora 15, and am trying to run a program that uses gsoap/soapcpp2 2.7.17 to communicate with different parts of the program. As far as I know everything has compiled correctly and I am using the same versions of the required libraries as several working installations. However, every single time the program tries to open a port, the program is unable to do so. This happens no matter what port I specify.
if there is anything in fedora that would limit or disable the ability of the program to open a port to start communicating. I have tried disabling the firewall with no change to the behaviour.
Ubuntu Security :: Disable The SSH Key Access?
Jun 15, 2010I currently have a user on my Ubuntu server that I want to block completely from login. I know right now they login with SSH keys so they don't need to enter their SSH password. Can anyone tell me how to remove the SSH key login for their username and root user which I believe they use too and block SSH access alltogether.I will then just change the root SSH password.I'm terrified they will do some harm so I need them blocked out ASAP.

Sep 3, 2010I've made an SSH server using OpenSSH on my desktop Ubuntu (10.4) for tunneling. However, I'm noticing that the public account I made for my SSH (one to give to friends to use proxy) has SFTP access to crucial system files. I'm okay with SFTP being enabled on my account, but not on this public account. Does anyone know of anyway to either disable SFTP to that user, or restrict access to important files?

Jun 19, 2011Set up a few machines yesterday to test out some parallel code. Just for fun, I selected the "encrypt users files" option when setting up Ubuntu (10.10). I had never used the option in years past. Now I'm finding it a pain. EG., ssh requires me to already have a login to the machine before it will let me log in w/o a password (eg., using id_rsa.pub and authorized_keys).
Similarly, I have no reason to encrypt files on these machines. They're just crunching numbers. Is there an easy way to disable this? Or do I need to delete my original user and make another one (with all the su privelages, etc...) w/o an encrypted file system / home directory.

View 7 Replies View RelatedUbuntu Security :: How To Disable Apt Authentication Check
Apr 3, 2011having a slow internet connection, I bought the all maverick repository on DVDs, copied the files on a usb drive and modified the apt sources file to consider the local repository only:
Code:
# deb file:/var/www/ubuntu_local/ ./
deb file:/var/www/maverick/dvd1/ maverick main universe restricted multiverse
deb file:/var/www/maverick/dvd2/ maverick main universe restricted multiverse
deb file:/var/www/maverick/dvd3/ maverick main universe restricted multiverse
[code]....
Even though I am reasonably sure it is safe, this local repository is not authenticated and I can only install package through the command line or synaptic, the Ubuntu Software Centre giving an error message "Requires installation of untrusted packages"...I thus would like to disable the apt authentication check for this local repository.

View 1 Replies View RelatedUbuntu Security :: Dangers Of Port Forwarding?
Feb 4, 2010Up to now I've been playing with Ubuntu whilst storing important data elsewhere for about 2 years. Now I'm ready to move to Ubuntu completely but want to address my security.I'm currently using a desktop and server behind a hardware firewall / Internet router. The router has DynDNS and forwards port 80 to the webserver and a port I picked at random to the desktop 22 for SSH with private keys. SSH passwords are disabled.
The first question is, is there a danger of running different security levels on the two machines? I don't care about the server, there is no data on it so I currently forward port 80 and am considering forwarding ports 631 (CUPS) and a port for LDAP. Will this effect my desktop (which has info I don't want to loose).The next question is whether port forwarding / hardware firewall is actually a safeguard against attack.

May 13, 2010I'm trying to SSH into my home computer from a remote location outside of my house's LAN and can't figure out remote port fowarding.
The guide here says to use the following:
Code:
I've tried connecting to my home computer through many combinations of the syntax listed above, read the man file, and looked online for help. But can't find out the proper syntax or a good guide that isn't written for Windows users using Putty.
Let's assume for the sake of simplicity that the public IP address of my home SSH server is 123.123.123.123, the private IP address of my home SSH server is 192.168.1.100, my home SSH port is 2222, and the SSH port at my current location is is 22. How would I write out the command?
Every time I try to connect I get a "connection times out" error.
Ubuntu Security :: Only Allowed To Use One Port For Proxy?
Jun 5, 2010I'm using a local proxy server VPN'd to another network.
How do I setup either Firestarter or Gufw/ufw to ONLY allow in/out from ONE port? (The one port the proxy uses)
Ex: Firefox is proxied to 127.0.0.1, all ports, and then the proxy picks it up, and sends out on port xxxx, and recieves on port xxxx, then sends back thru 127.0.0.1, back to Firefox.
Any setting/rules I've treid on either Firestarter or Gufw kills the proxy>VPN (Proxy won't connect to remote network)
Addendum: If I start the proxy FIRST, then the firewall, all is good. I'm thinking the proxy uses a port to connect with remote network first, then switches to my configured xxxx port...hmmm
