Ubuntu Networking :: HTTP Rewrite To Internal Server?
Nov 11, 2010
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 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.
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 a base install of a LAMP server on my system, and I'm trying to get mod_rewrite working on that local server (the directory of the local site is [URL]. I added this to my /etc/apache2/httpd.conf file, which was blank before I did so:
Code: <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow [code]....
It's supposed to redirect everything except the listed directories to index.php, which is used as a front controller. However, if I type in [URL] <any other page> I get a 404 error.
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?
Using netcat, nc(1), craft a valid http/1.1 request for getting http headers (not the html file itself!) for the main index page of www dot aalto dot fi. What request method did you use? Which headers did you need to send to the server? What was the status code for the request? Which headers did the server return? Explain the purpose of each header.
nc -v www dot aalto dot fi 8080 HEAD / HTML/1.1 host: www dot aalto dot fi And it returns: 200 OK Content-Length: 858 Content-Type: text/html Last-Modified: Thu, 02 Sep 2010 12:46:01 GMT [Code]....
I really don't know what does it mean. Question 2: Using netcat, nc(1), start a bogus web server listening on the loopback interface port 8080. Verify with netstat(, that the server really is listening where it should be. Direct your browser to the bogus server and capture the User-Agent: header "Direct your browser to the bogus server and capture the User-Agent: header" I don't understand this question.
Ok so I've been all over Google trying to find an answer as to why my MPD server won't properly output over httpd. When I try to connect to it from any source, it gives me a "404:Entity Not Found" error. There hasn't been any useful info out there to solve this problem. Help please! Attached is my mpd.conf file. All my permissions and firewalls are set up properly AFAIK.
I have recently downloaded and installed apache2 http server from tarball source (i'm running ubuntu but i think its more fun to use tarballs i don't know why but its how i am) anyway i just installed apache2 and when i go into the servers section of webmin and click on apache web server i get this message:
The Apache server executable /usr/local/apache2/conf/ does not exist. If you have Apache installed, adjust the module configuration to use the correct path. and when i go to the configuration menu i don't understand a word of it.
How can i build an internal dns server for my network, but don't use the top level domain, e.g:. mycat.com. I want to use mycat.kgn. And I want to put a mycat.kgn mail server on the network for internal uses.
My setup: dns mx mail2.mycat.com (my server) mx mail.mycat.com (godaddy) inet-gateway & firewall & mailserver: centos 4, mail2.mycat.com nic1 - internet nic2 - 192.168.0.1 kerio email server 6
All workstation & server uses: ip: (below) netmask: 255.255.255.0 gateway: 192.168.0.1 dns: 192.168.0.1
Workstations: windows & linux nic1 - (192.168.0.20 - 192.168.0.199)
Printers: HP laserjet jetdirect (192.168.0.211 - 192.168.0.249)
Config: I need a dns server with: dns mx zimbra.mycat.kgn 192.168.0.127 A mycat.kgn 192.168.0.1 A samba.mycat.kgn 192.168.0.128 A www.mycat.kgn 192.168.0.1 NS ns1.mycat.kgn 192.168.0.129
All workstation and servers: ip: (same as above) netmask: 255.255.255.0 gateway: 192.168.0.1 dns: 192.168.0.129
ldap all machine to zimbra.mycat.kgn for login info and password. map drive g: to samba.mycat.kgn data-share (with users rights from ldap)
I tried to do this in virtualbox, but fail badly! I created 6 vm using ubuntu 804 and 910, but my dns was not getting any records with dig, so I found an howto on powerdns. But I had to use mycat.com and not mycat.kgn?
I will draw my network to be! each machine: ip: (sameas above) gateway: 192.168.0.1 dns: 192.168.0.129 dns-nameserver 192.168.0.129 nameserver 192.168.0.129 and if the dns server does not find the info it forward it to the gateway 192.168.0.1
Basically, i want to be able to type a domain in my browser e.g. default.dev and it direct to the ../www/default folder on the Ubuntu Server on my network. The reason being is that as a web developer i have a number of sites that i'm working on locally and i'm getting tired of adding the domain to my hosts file and then creating a virtual host in Apache - i believe this can be done with BIND - is this right? If so what steps are required?
I have an apache server running on my ubuntu machine. I can view them using my local ip (192.168.1.6):80/. And my friends can view the things hosted on my server using my external ip (example http://123.123.123.123:80) but when a friend links back to me to show me what they are looking at and share the moment, I can't view the link, it simply redirects to my router login page.
I had an older linksys router and this could work fine. I could click on the links with my external IP and it routes back to my server for viewing.
Remember to note that I am on the machine that has the server, and I'd like to be redirected out and back to it so we can share pictures back and fourth without me having to replace the external IP address with my local one just to view that link in the browser.
I'm trying to set up a server for an NPO who connects to the Internet through an internal proxy (Websense). I can't access the Internet unless through the proxy.
Since it's a server I did not install a GUI so I'm wondering how to connect the new server to said proxy server. I have the IP address, port number and username-password for the proxy server. The new server has a static IP address and is ready too go!
I want to redirect [url] to [url] how to do this? The only solution that came up is just redirect everything to a php file, and than ask the php file do the redirect..... I want to do it using .htaccess file instead of using PHP or CGI.
Some time yesterday, I lost the ability to ssh my remote server, or even visit any webpages it hosts.
I've explored hosts.deny, /var/log/secure and even turned iptables off to see if it would fix anything. To no avail. Here's what my ssh login attempt looks like:
We have a apache server which have a ssl certificate like www.abc.com. We hosting a website is a online giving shop which need ssl cetificate in https. website of this is www.123.com, it will redirect tow this website owner don't want to show What can I do to achieve this ? Can I use rewrite function in apache to achieve this? How? or we need to buy any other ssl certificate for www.123.com? How can I install multiple sslcertificate in one apache server?
Basically, I have a windows 2003 server virtual machine (vmware) inside Ubuntu 9.10.
The Ubuntu machine has IFconfig: Code: sam@sam-laptop:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:15:c5:b8:c8:8b UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17
Why can't I ping or simply access the internal server on my ubuntu machine from a another computer on the 192.168.1.0 (slash)25 physical network? Do I need a bridge? Iptables?
I have been working on this for the last couple of days, but I don't seem to be getting anywhere with it.
I have a Fedora 12 64bit Server set up, and for the most part it's working Great. I have 3 VHost set up, and no problems with that.
My problem is I just moved my Wife's xcart store from Godaddy to this server. And the store works great. But xcart is set up to use Clean URL's, and this is what I seem to be having all the problems with.
In my "httpd.conf" file, I have "AllowOverride All" to use ".htaccess" and in xcart ACP I have it set to use Clean URL's. I added a ".htaccess" file to root folder, with this in it.
Quote:
Now if you try to log in to the store with just the base url "www.my_site.com/" I get a the Apache Test page. But if I enter "www.my_site.com/index.php" the Home page opens, and all clean url's from there work fine. ALL other pages will open just fine. So clean URL's is working. Its just the home page that won't load right.
Now if I change the ".htaccess" file, and set "RewriteEmgine Off", then the home page will load like it should with the base url., but then "Clean URL's" no longer work. I have to change "AllowOverride All" to "AllowOverride None" and turn Clean URL's off in the ACP of xcart. to get the store working again.
Then the whole site works just fine, just No Clean URL's. I'm at my wits end with this, don't know what else to try to get this to work. So I was hoping someone here might have an answer, or at least some ideas to try. This all worked just fine on GoDaddy's site, I left because it was just too dam slow. It took a minute and a half just to load the Home Page. On my server its less that 2 seconds. And every time I asked them about it, it would speed up for a few days then slow down again. But the same .htaccess file worked on that server. So I think my problem is in my "httpd.conf" file just don't know where.
I need to have a postfix server to rewrite the sender's address. For example, if the sender is: [URL], then the recipient would receive all emails from [URL] as [URL]. I tried using the generic file and created a table out of it, but this did not work:
postmap /etc/postfix/generic -rw-r--r-- 1 root root 9977 Dec 27 15:24 generic -rw-r--r-- 1 root root 12288 Dec 27 15:25 generic.db
I added this line to the generic text file:
[code]....
I am running two boxes with postfix 2.3.3. and 2.1.1 respectively. Both need this configuration. I also added this line:
smtp_generic_maps = hash:/etc/postfix/generic
on the main.cf file. However, this did not work. The one running postfix 2.3.3 is on Centos 5.5, the other one is on SuSe Enterprise 9.
I've moved a web site from one server to another.I'm also moving the domain name to the new server.In Apache I've got the web site configured up and running with no problems. What I'd like to know if this is possible. I'm wanting to avoid a complete web site rewrite. I've looked into mod_rewrite but I don't think this is right.I only want the web site to look aesthetically pleasing. So if it's not possible so be it. (I'm not a programmer but do have access to the code)
I'm trying to setup a Centos 5.6 Squid Proxy Server with Content Filtering & Antivirus Scanning Incoming HTTP Traffic from the Internet
I then proceeded to setup an configure the Proxy Server, i was able to test and confirm that Squid and Dansguardian Content Filter is working, however i dont know if Clamav is scanning HTTP traffic before it hits the client/server. Is there a way i can check if the Antivirus scanning is working.. is there some log file or real world test i can i can do to confirm that Clamav is scanning incoming traffic or even blocking potential viruses ??
Anyone who has squid proxy server with Clamav configured and its working can share there settings/setup with me and how they tested it ??
redirect a domain name with /abc to external ip of web server. Now I can made sure that I should use the rewrite module to achieve this issues. But I don't know how can I enable this function in my apache web server. I will post my httpd.conf for your reference.
I have a website example.com, serving pages on port 80. I want the url example.com/redmine to be rewritten to port 3000, where my redmine server is running, without actually changing the URL. So the user typing in example.com/redmine/test would serve up example.com:3000/test, without the user actually connecting through the port. I know this can work through CPanel, but I don't know exactly how it was implemented. I'm looked at how mod_proxy, mod_proxy_html, and mod_rewrite,
I'm trying to set up my web server (nginx) as a catchall virtual host, as per an example that can be seen here: [URL].. (It's the Wildcard Subdomains in a Parent Folder example). Now, here's my issue. I use Wordpress on the coburndomain.org domain. I have pretty URLs enabled, that make my Wordpress articles look like this:[URL].. At the moment, nginx is reporting 500 Errors, saying that index.php is not a directory. What I want to do is make a rewrite rule that allows me to use the above URL example with nginx.
I followed this tutorial to do so: [URl].. , but I'm not sure how to apply it to my setup. Here's my configuration files from Debian Squeeze with Nginx onboard:
I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?
