View 4 Replies View RelatedI used Avast webfilter (proxied webtraffic through Avast) when running Windows. Sometimes Avast would alert and "protect" me from being infected by a compromised website. NOTE: Avast would alert even absent clicking any links. Just viewing the page could result in infection. Should I be running some kind of proxy webfilter for protection? My understanding is that Firefox can be compromised and this can in turn compromise Ubuntu.Are these kinds of threats specific to Windows running Firefox, or Firefox per se. If Firefox per se it seems like I need some sort of Proxy webfiltering like Avast provides.

View 1 Replies View RelatedI want to block some ip address that are attacking my server and making my ssh port busy. On searching the google, I found
Code:
iptables -A INPUT -s ip_address -j DROP
I will add this rule in iptables. My questions are:
1) do I have to do
Code:
chkconfig iptables on
so that it load the iptables at boot. I am wondering why do I need this because iptables is already modified and it loads the iptables at boot time if firewall is enabled.
2) When we add the above rule, which file is modified? Another way, where are this rules stored? It is not in /etc/sysconfig/iptables and /etc/sysconfig/iptables_config.
securing VNC connections by tunneling the connection over SSH. However, from the server perspective it will still allow an unsecured connections and you're relying on the client to setup up the SSH tunneling. Is there a way to configure the Linux server to now allow connection over an unsecured channel?

I am having a web server (apache) and 3 sites are hosted in it, named as www.web1.com,www.web2.com and www.web3.com.
I need to restrict www.web2.com to Internet users and allow only to local network. At same time I need to allow www.web1.com and www.web3.com to both Internet and LAN users.
We have 4 servers having rhel 5.2. We have several users logged in on one of them. We have nis server/client running on them and have common home area mounted on all of them. Now we want to disable/block the accounts of the users who have not accessed our servers in last 2 months from today.What logic should we apply to do so? We were checking stat of .bashrc of each user but is not correct logic. We are going to write shell script for the same. We dont want to do anything in users home area or their files.

View 1 Replies View RelatedA couple of weeks ago, I completed a system upgrade that was motivated because I have to deploy Windows 7. I have to deploy it because my Windows development environment is getting very long in the tooth, and I have to become current again for a project of mine that is underway. So, yesterday, I deployed Windows 7 Professional in VMware 7 hosted on Mandriva 2010. With my new upgrade, I have a very capable quad-core athlon system with an NVidia 240GT video card, and it runs Aero quite nicely in the virtual machine. I do have to say that Windows 7 looks nice and isn't too annoying to use, except - of course - when I need to dig into it to change some setting or another.
Now, on Windows, for many years I have used Zone Alarm firewall rather than the Windows firewall, because ZA monitors and controls outgoing connections. I have used this on both my Win2K development system (virtual machine) AND my Win XP laptop to keep microsoft applications (notably media player) from calling the mother ship when I didn't think they should. It has worked well. So one of my first actions was to download the newest copy of ZA free firewall and deploy it on Windows 7, after disabling the Windows firewall. Well guess what. ZA doesn't stop Windows from calling the mother ship. I have all settings on ZA set to "ask" before allowing anything to contact the net, but I've been playing with some multimedia things and the microsoft software has been talking on the internet as happy as you please, and ZA hasn't asked me a single time if it could do so.
Of course, when I ran a few tests with ping and tracert, ZA asked me. Also, I had to fiddle with ZA settings a bit to get the Windows 7 to successfully talk to my LAN. But when Windows 7 wants to talk to microsoft, it talks regardless of what ZA says. Well, when you get down to it, this is one reason I have Windows running in a VM...I WILL be in control, regardless of what microsoft wants. Does anyone know of a tool that I could use from Mandriva to prevent a VMware client from talking to a website? I'd like to be able to easily enable/disable it so that I can let Win 7 talk to microsoft when I need for it to do so, but no other time. I'm using bridged networking in VMware so all my virtual machines have their own IP addresses, but of course all of them (as well as my host Linux system) go through the same network adapter. It seems to me that iptables would have to work for this, but I'm not at all sure how to set it up to do it given the bridge.
I don't care so much the practicality and needlessness of actually setting up a computer for proxy server for personal usage, but none-the-less, i want to do it, and i'm just wondering about hardware.The proxy, i don't intend on having a desktop environment, so it'll be a terminal interface.But for a system that will handle traffic for 3 pc's and a ps3, how much hardware would one suggest i need, as far as RAM, HDD space, so on and so forth.
I was thinking it would be fun to do with with my old amd k6-2 processor and it's 32mb of ram, but in order for that pc to work, i'll need to replace a few hardware pieces, and before i dumb money into it and pull it out of the closet, i want to find out if it would even be worth my time to do it.
I run a HTTP/HTTPS proxy server but one of our clients is having trouble accessing [URL]Can anyone see if the login button is using some kind of weird connection feature? I thought it might be using flash or something rerouting the connection through something other than port 80 (or 8080 for the proxy) but not sure if that is the issue.I just used a fake login and password but instead of giving me the incorrect password error the page just hangs.

1. I understand you can protect your files or directories in your website by setting file/directory permissions. The meaning of r w x is clear to me, but I'm not sure how to proceed... Starting with the index.html file, if I wanted to make it so that anyone in the world can read it but can't modify it, do I set its permissions to rwxr-xr-x? If I set it to rwxr--r--, would that mean the file couldn't be served? I mean, what does the x setting do on a .html file, how can a .html file be executable?
2. If file permissions work on the lines of owner-group-others, in the context of a website, who is 'group'? As far as I can tell, there's only the owner, which is me, and others, which is the world accessing the site. Am I correct in thinking that by default, say when creating a website on a shared hosting server, there is no group unless I specifically set one up?
3. My ISP allows the DynDNS.org service, meaning that I could serve a website from my home. It's too early to go that route just yet, but for future reference, I would like to ask about the server software called Hiawatha. It is said to be secure, but having read some evaluations of it, it doesn't seem to offer anything that couldn't be accomplished with Apache or Cherokee, it's just that its security settings are simpler and easier to configure. Am I right about this? Or does Hiawatha truly offer something that the other major server packages don't?
