Security :: If Visiting An Https Website Is There Any Added Benefit To Tunneling Through Ssh
Apr 4, 2011
Basically, whenever I am on an unencrypted wireless hotspot, I open up an SSH tunnel to my home server to do all my browsing for the privacy and security it provides.But I got to thinking, and now I am curious, if I am visiting a site like gmail for instance that always uses SSL/TLS for it's connections, is there any added benefit to also using an encrypted tunnel? or is it perhaps superfluous to use both

On my website/blog I've gotten a couple of comments having what seems to be regular content (name, mail, message), but where the sender website field is set to "http://Yourwebsite". I find it strange that two comments from separate individuals fill the sender website field with this text. Is this possible to find out if these comments are spam or not? Based on the messages alone they don't seem to be, even though it is possible. From what I know the comments code don't enter this value by default.

I have the following details on my system:
- CentOS
- RHEL 5
- WebWare for Python
We have an exisiting website written in Python and was developed by other entities and now being maintained by us. We want to run the website using secure connection (HTTPS), I tried reading this article and successfully executed every instructions but still failed to run the website using HTTPS.
[URL]
The way we run the website is using port 8080, e.g. [URL] I am sure I am missing something here, first, I am still looking on where does the port 8080 comes from since I've checked the httpd.config and it wasn't there.

I have a local computer (local), and remote computer (remote) behind of remote server (server). Also, I have user access to all of these 3 machines. Now, I want mount some directory, located at remote, to my local mount-point via sshfs. How should I setup my local sshfs and what should be done on server to make this mounting?
I'm stuck with ssh tunneling because the default method for tunneling requires root access while WinSCP somehow could do this with only user access (the tunnel server could be configured there in 'tunnel' panel).

I bought a mlb.tv to watch baseball game online and they have blackout for local teams. I try to use proxy sock to bypass the blackout, but for some reason they know my location because I'm getting blackout. I check to see if they were just checking for proxies and I went and I try to watch other games not in my area and I was able to watch it. I use this command on the ssh client "ssh -D 9090 user@domain.com" and I change the setting on my network. I do a ip lookup and the ip address is from the server location. I dont want you guys to tell how to bypass, I just want to understand how they know my location.

I am attempting to set up a VNC with ssh tunneling for remote desktop between my laptop (opensuse 11.2) and my desktop (kubuntu karmic) and using the instructions here: [URL] and here: [URL] but I am having trouble getting remote desktop to work once I establish the ssh tunnel
I start out with
Code:
ssh <user@remotepc> -p <non22port> -L 5900:localhost:5900
That seems to wok and connect properly
The problem comes when I try to use a remote desktop client on the laptop to initiate the VPN desktop sharing and point it to
Code:
localhost:5900
Thats when I get a notification on the host saying:
Code:
Refused uninvited connection attempt from 127.0.0.1
And on the laptop I get:
Code:
VNC server closed connection
I have tried messing with the few settings in Krfb, but none seem to have any impact. How do I open localhost:5900 and allow VPN tunneling to the host machine?

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?

Is there a plugin or some other way to check to see if a website has https available, and use that instead? I know some sites, like Wikipedia have a different hostname for SSL support while others have the same hostname, just What I would really like to seesome kind of header in the http reply or the html that saysSecureAvailable= is there any system like this in place? There's too many issues with with unencrypted http to continue having that as the default.

I have tried to configure my iptables to allow only HTTPS connections to the internet. Unfortunately, I didn't get that to work. I configured it like this:
Quote:
iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A OUTPUT -t filter -p tcp --dport 53 -j ACCEPT
iptables -A OUTPUT -t filter -p udp --dport 53 -j ACCEPT
[Code]....
Of course I am only trying to access websites via HTTPS Still, I was wondering if HTTPS somehow under the hood requires the HTTP port to be open or if my rules are in some other way wrong.
ps: I got the rules from that website: [URL]

When connecting to an unknown unsecured wireless network, is it possible for someone to capture a header and resend it even if it's over https? For example I login on an ipod or on a computer and connect to a server through https and password auth. Although anyone monitoring the transmission could not get hold of my password since it's encrypted, could they just capture the header and resend it 5mins later to logon again without even knowing the password?

I have an ssh tunnel with my ubuntu (vps) server. On my local computer I have proxifier, to redirect everything with socks5.
Everything works fine, I can browse websites and that. Email also works.
But when I want to visit a website that uses https it doesn't work. I do not get to see the website, or receive an internal server error.

I am working on a project to create a video conferencing environment. For this I use a default installation of BigBlueButton on ubuntu 10.04. One of the main problems here is that it's not safe enough to share classified documents trough this software. It's a simple webserver that uses nginx. What I want to do is make this connection secure.
One of the problems is that I don't only have a connection trough port 80 but it uses the following ports:
Port 80 (HTTP), 1935 (RTMP), 9123 (Desktop sharing).
I would like to use a proxy instead of some tunneling or vpn to do this. Would anyone happen to know anything about squid or another equivalent to do this?

I'm trying to figure out how to use ADrive.com's 50 GB's or SkyDrive's 25 GB's of free storage to backup my computer automaticaly.
Problem's:
1. With ADrive I can select all my files at once through their website's uploader vs SkyDrive where you have to select them one by one. There are some third party programs, like Gladinet, which will mount sky drive to your computer like an extra drive, though I haven't found one for linux yet. This guy came up with a cool way to backup automagically with Windows: [URL] I am trying to figure out how to do the same thing with Linux.
2. ADrive's uploader is not on https, whereas SkyDrive is. Either way I wanted to encypt my files on my computer first so when I back them up, they are safe in case they should fall into the wrong hands, not that I don't trust Microsoft or whoever ADrive is with all my most precious documents, but I'd rather error on the side of safety.

Anyone running fedora 11 have any luck getting a smart card reader added as a security device under firefox?
Specifically from firefox: Edit-Preferences-Advanced-Encryption tab-Security_Devices-Load;
Enter arbitrary name and "/usr/lib64/libcoolkeypk11.so" as the module.
This worked fine in fedora10 and was the necessary step to getting a card reader to work with firefox. In fedora11 (with firefox beta) the browser just comes back with nothing, it doesn't even respond. Note I am familiar with the concept of pki and certificates as well as certutil, pkcs11_inspect, pklogin_finder, etc. Also note utlities like pkcs11_inspect and pklogin_finder and esc all work and communicate with the reader and read the contents of the card but smart card login configured via the authentication applet (as working in fedora 10) is not working either.

I'm working in Ubuntu 9.04 Desktop with Apache installed. I have a directory /var/www/test:drwxrwxr-x 5 root www-data 4096 2010-01-04 13:51 test And I've added myself as a member of the group www-data. Problem though is when i go into /var/www/test I still can't do anything, whether it's creating a new file or directory or editing files there. The files within the directory are also 775 and setup under group www-data.

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.

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 don't care for domain 'authentication' by an "Authority". I don't trust no one, so CA's to me are as trustworthy as the gypsy in the park.
I can use a self-signed certificate, but the problem is most browsers makers are Fn idiots that say the connection is not secure, when it actually it, but because I did not folk out cash, it makes my website look bad.
I can understand the need for a 3rd party to verify the domain host to prevent man in the middle attacks, but I do not care for this.. and browser makers should take more responsibility and introduce different padlocks for types of authentication, rather than saying "this connection is encrypted, but not secure because its self-signed". What a load of horse s***!
How many times does people stop to read certificate authorities? I sure don't. I only care weather or not the connection has been encrypted.. so, I am looking for a way for simply providing encryption for my website.
From what I understand, when you submit a CSR to a CA, it includes the private key, meaning that the CA would be able to see the encrypt data, should they get hold of it. This is not acceptable for me.
Is there anything other way to use encryption other than the SSL model that is used typically amongst HTTPS browsers today?
