Ubuntu Servers :: Linking Internal HTTP To SSL Encrypted Site
Mar 28, 2011
A church I've been working with has a CCTV system that has a web interface for viewing the camera feeds. We need to see the page from the outside, but it is just an HTTP page, no encryption. The box itself does not accept any sort of SSL encryption. How I can get this on the net in a secure way? At worst I could set up a remote desktop type solution, but I was really hopping I could use some apache magic and just re transmit the page to https and ssl encrypted.

I installed Nagios on my Ubuntu 10.04 server using apt-get and when I accessed the web console, everything was OK. I made some changes to apache (creating some new virtual sites) and since then Nagios gives me a warning message for HTTP with the message, HTTP WARNING: HTTP/1.1 404 Not Found. The sites that I created are working perfectly. I noticed that the attemps are 4/4. Does this need to be reset or does Nagios automatically reset that once it detects the issue is resolved?

My squid configuration is based on a whitelist only basis.
Im trying to do a dynamic whitelist for squid, which allow URLs in the whitelist when the requested URL comes from a trusted search engine like www.kidrex.org. However, when i access www.example.com and tried and find www.kidrex.org on the referer column, i could not see www.example.com as the requested websites.
Any idea how to get pass this problem, else i would have a hard time building my whitelist, which is not dynamic at all

I have a registered domain that resolves (via dyndns) xxx.mydomain.com to my external facing router -easy no issues there. Behind the router I have several machines (some VMs) running webservers, mail etc... What I want to be able to do is redirect the external traffic based on xxx to the relevant internal machine and serve the content back to the external world.
I have tried using a http rewrite of xxx.mydomain.com to the relevant machine an it works fine from within my network, however externally the re-direct fails as the master DNS servers have no record of internal DNS setup in my network (obviously).
So is there anything I can do to get xxx. recognized externally? I'm only just starting to get my head around how DNS, HTTP, TCP etc all hang together. Am I barking up the wrong tree with rewrite? Should I be looking at proxys?

I've never figured out a good program to use with file globbing from http sites. Wget works with ftp sites and file globbing and for mirroring I use lftp, but I would really like to download just the files that start with "xf" from Robby's site.

My company web access is behind proxy(http://abc.proxy). Network admin can get to check who is top10 user and web they access. I owned a centos server. I have a thought that create an encrypted tunnel within proxy so the admin cant detect my http address. This is how it going to works
client with OpenVPN -> OpenVPN server(centos with company proxy)-> proxy -> internet
My connectivity in my client are using OpenVPN server as bridge. Hence, no record for client is recorded in my Network admin monitoring list. OpenVPN server's activity can be traced by network monitoring tools, just assume that our ultimate goal is to hide client activity.

i am forwarding HTTP request to a internal server, it is quiet successful but access logs donot show the ip of the external m/c. Rather it shows the ip of the machine on which i have enabled port forwarding.

In the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?

We're having an issue with HTTP POST file uploads on our two Ubuntu PCs. For some reason, whenever one of our users attempts to submit a file in an HTML form, the request times out, usually with a 500 Internal Server Error message. This problem is not limited to one site, but occurs on all sites that use file uploads. Also, the problem does not appear to be with our network, as a Windows 7 PC on the same network can upload files to the same sites without any difficulties. The problem is not browser-specific; we have tested with Firefox, Epiphany, and Google Chrome and all produce the same results. The issue is relatively new, and was first observed within the last month; before this time, both machines had no problems uploading files.
Does anyone have ANY idea what could be causing this? I've tried a number of things, including rebooting the PCs, rebooting the network, disabling IPv6, etc. I'm not very experienced in Linux system administration, but I can use the terminal and am familiar with some terminal-based diagnostic tools, so if you need any additional info or want me to try something, please let me know! I've exhausted my own computer knowledge with regards to finding a solution to this problem.

I have written an OpenGL based program which uses i.a. libjpeg that I want to link statically so I can send it to someone who doesn't have all the libraries needed installed to allow for a dynamically linked executable to run. As such I tried with giving the [b]-static[b] parameter to gcc.
Code:
x86_1$ make
gcc -O3 -c jpegloader.c
gcc --std=c99 -O3 -c --std=c99 -I/usr/include -L/usr/X11R6/lib main.c
[code].....
Why would gcc claim that I'm missing GLUT? This works perfectly fine when I do dynamic linking -- i.e. omitting the -static argument.

We have one office with a simple samba server running on Lenny; not a PDC, just simple username/password authentication. It also acts as a DHCP server, NTP server, and DNS server. All clients are windows machines (mainly XP Pro, but also starting to get Win7 show up). For remote access, most users have chrooted WinSCP; OpenVPN was setup, but too slow for most AutoCAD uses (our primary application). It is still used by a few people, though.
I need to set up a similar system in another location, and need to provide access to both servers. People mainly access files stored in their own office, but will occasionally need to access files in the other office. In intend on having both run the same version, whether I stick with Lenny or put both on Squeeze.
I was thinking of setting up both servers, and then mounting the remote file system (the "other" server) over the internet, possibly via sshfs, but do not know if it is reliable enough. Or perhaps via OpenVPN connecting the servers, but then the overhead of the VPN may become an issue, adding lag time. The remote shares would then be accessible via the samba config.
Are there other options that may be easier to set up, more reliable, or more secure? We do not want a domain set up, just simple workgroups. Since many are using their personal laptops, joining them to the domain can cause some problems. It would also require more effort to add a new computer, and with the constant stream of outside consultants we use, that could get cumbersome.
My main issue: no budget beyond the low cost box for the second file server, so it has to be an open source solution from start to finish.
I'm not quite a newbie - I have quite a bit of experience setting up and maintaining basic Samba / DHCP / ssh servers - but not much beyond those. I certainly am open to learning new things and doing the research, but my head is swimming with all the options I have come across.

I have a wide area network with 7 CentOS servers running Bind and 1 Windows 2003 server. All 8 of these servers handle DHCP and DNS at their respective locations. At each site I can ping computer.site.company I'd like to be able to resolve the dns names from site to site. So from site1 I would like to be able to ping computer.site2.company and get a response.

I am currently finalizing a SSH Tunnel (gSTM) via Ubuntu Server (see: [URL]). The gentleman who helped me there went above and beyond the call of duty as we used to say in the military. Accordingly, I wanted to start a new thread to explore options to the pending completion. So, several systems in play here. I will list two of the three with the presumption that the SSH situation is in play (testing it today from outside of my network).
Systems Currently in Play: Ubuntu 10.04 Desktop Edition with all updates as of today's post: Server: Acer Aspire AST180-400A. It is currently being accessed from Ubuntu 10.04 Desktop Edition with all updates as of today's post from a laptop: Toshiba Satellite A200. Router: Netgear N300 WNR 2000v2. Modem is Motorola Netopia 2210-02-1006. Proposed System To Add: eMachine ET1331G-05w running Windows 7. Why? Well, my girlfriend is terrified to ditch the Bill Hates way of things. It is running through the router currently as well.
What I would like to be able to do is access the Windows 7 desktop via my laptop on the road as well. Specifically, I need to be able to access and view documents and photos. Now, the docs are at least in OpenOffice; she switched to it finally. I would like to also be able to view my desktop to access docs and pictures on the server, but that may be a new thread as the Win7 situation is the priority right now.

I'm migrating a site from one VPS to another, and I'm having trouble understanding what I need to do with DNS. I haven't even gotten to the nitty-gritty of it: I don't understand it at a very high level. My host sent me this email explaining what I need to do, and I don't even know what questions to ask.
Quote:
Your registrar has MyHost's nameservers listed for your domain name.
All DNS-related info for mysite.com and everything inside that zone is defined in your zone file which is currently on your VPS "myserver1" and is being rsynced to [our] servers.
I'm suggesting that if you don't want to spend any of your migration time setting up a DNS server then you may wish to just make the changes in that file, since that is the method that is currently working.
I've come up with two possible interpretations of this situation, and perhaps neither is correct.I need to set my new VPS to be its own nameserver, and have my registrar point mysite.com to my VPS. I need to set up a DNS server to somehow interact with MyHost's nameservers (something about a zone file). Do either/both of these sound plausible? I thought DNS made a server into a nameserver, is that not right?

Im trying to just set up my web page so it can be seen on my local home Lan (then Ill try to get it on the internet). I can see the site it on my pc but other network users cant.
They can ping my computer but cant telnet to it on port 6060 (thats the one is set the server up on)
What's wrong with my configuration its mostly the default with a few changes that I hoped would make the site work.
My ip 192.168.1.10
Here is the sites-available default file

Right now my server is being used as a Minecraft server. I have a site hosted on it, but my ISP blocks port 80, so I'm the only one who is able to view the site. I want to be able to change the port the site is on so that anyone can view it. I've looked it up and apparently that is possible; however, I haven't found out how to do it. I've changed the ports.conf file in /etc/apache2 and the default file in /etc/apache2/sites-available, but it didn't work. All that did was take my site off of 80, but it did not put it on the new port I specified. What exactly do I have to change so that when I go to mysite:port, it loads my website?
EDIT: Also, just for extra information, the two ports I tried were 8080 and 81.

I have Ubuntu Server (x64) installed on my box with Apache2 and Squid. For awahile port 80 (http) was fine, I could update packages and use wget. Then one random day port 80 became blocked for incoming traffic. I couldn't use apt-get and had to change to an ftp mirror to update. Also wget is not working.

A while back, I put a site up under a LAMP setup, and followed a guide from ubuntuforums that I googled to set up SSL encryption for the site.
That site works great, but since then, I've added some other sites to the same LAMP server. They load fine as well, but if I type in https:// before going to the latter sites, the browser attempts to redirect to the first, and warns that it is a fraudulent certificate, and that I'm at risk by going to the site.
Obviously, it isn't an attack site, the certificate is just set up for only one domain. How do I prevent my non-SSL sites from redirecting to the SSL-encrypted site?

Does anyone have any recommendations on what software I can use so I can FTP my site's files to the /var/www directory? I tried using vsftpd, but the software was terribly difficult to configure correctly. I tried telling it to make everything that was uploaded have "704" permissions, but everything I uploaded had strange permissions on them. When I used to use professional Linux hosting, that was never a problem, so I'd like a simple FTP server software so I can easily manage my site from a remote location.

I am running a website using a Fedora 9/ Apache 2 platform. I have added two new disks to the same server and installed Fedora 12 (I don't have both sets of disks in at the same time either the old ones with F9 or the new ones with F12). Having copied 'all' of the settings over to the new F12 installation it only serves pages on localhost not on the external IP as the F9 version does.
I have now installed F9 (got rid of F12) onto the new disks and copied the settings from the old installation onto the new disks and the server once again serves up pages. The only hardware changes are the disks being popped in and out between restarts as I swap between the old and new installations.
Hopefully there is some obvious (to someone) difference between F12 and F9 that would account for this.I have messed with settings for a while now and am almost at the point of paying for RHEL to see if that does the job.
