Ubuntu Networking :: Access Apache From Outside The LAN?
Mar 18, 2010
I have set up a hostname on dyndns.com and configured my router to forward port 8181, but I cannot view it from the internet (FF says "can't establish a connection to the server"). The DNS is ok, is just the apache webserver that doesn't work.
I can acces my webserver from
http://localhost:8181 (loopback)
http://192.168.1.1:8181 (in the LAN)
BUT NOT <hostname>.dyndns.com
Here is my site configuration
[Code]...
So, what's the matter? How can I reach my apache from the internet? Also, I read about routers loopback errors, but this seems not related to it, since I tried to get it through a proxy server, and it failed

I can connect to anything locally, I can SSH in locally but nothing works from outside my network (can't access pages in apache, can SSH, etc.) I've checked the logs I can think of, but what should I be looking for? The last thing I did today was add a FW rule to log and drop from an IP, saved my iptables to a file in /etc. (this was at 10:45am). The last time I successfully logged in remotely 1:03pm. I connected multiple times in between. I've rebooted remotely once or twice. That's it. I've already flushed iptables.

I'm trying to setup an Apache webserver on my computer in order to practice HTML5/CSS3 for an upcoming competition I'm in. I'm able to access my site from inside my network, but I cannot outside my network. I've had several people try, and they all report that the server just times out. I'm running Ubuntu 10.04 and Apache 2.2.17
My site is at [URL]
Here is the output of ifconfig
Code:
eth0 Link encap:Ethernet HWaddr 00:26:22:50:0f:0a
UP BROADCAST 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

I set up my first web server and it works flawlessly -when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.
I have two network interfaces on my server, eth0 (public static IP connected to internet directly) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1. It is connected directly to the internet and serves as a SNAT for other comps on the lan.I added "192.168.1.1 www_server_com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.HOwever, the server itself only opens website if the address islhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www_server_com ( I cant use dots as I do not have more than 15 posts on the forum )Here is the firewall script I am using.
#!/bin/sh

I am a newbie to linux of 4 weeks. I set up my first web server and it works flawlessly - when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.I have two network interfaces on my server, eth0 (public static IP connected to internet) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1
I added "192.168.1.1 www.server.com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.
HOwever, the server itself only opens website if the address is localhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www.server.com.I do not understand why the record in etc/hosts doesn't point it in the right direction. It seems that when I open address 192.168.1.1 it still gets routed to the external network. I have seen using DNAT to deal with the problem but it didn't work in my case (maybe I didn't do it correctly). I have spent whole evening/night trying to sort it out, it's 4AM now, going to bed frustrated and angry (at myself hahaha). Still like linux very much, won't be going to windows anymore. Please help

I am installing Big Brother on a CentOS 5.2 running the default Apache 2.2.3. When I try to access any web page I get the following error: Forbidden You don't have permission to access /bb/ on this server. Apache/2.2.3 (CentOS) Server at fmsubbnix Port 80 So far I have:
1) Set the Directory options to FollowSymLinks
2) Verified all directory and file permissions are at 755
3) Set permissions temporarily to 777 and received same error so I am assuming the issue is in a config file somewhere
4) in hhtpd.conf verified <Files ~ "^.ht"> is correct
5) verified the "default" directory is correct (/var/www/html)
I have read and tried several ideas in posts listed on the web but to no avail and am at a loss as to what to look for next..

just switched our company from windows server to linux and everything is going good except we have 4 vpn connections though out the country coming to our server. All giving the client machines ip addresses of 192.168.x.x based on where they are located 192.168.1.x for the main location 192.168.2.x for a second location etc, and IIS could see the clients ip instead of the wan ip and was setup to block all ips except 192.168.x.x ip's and this worked great.
So i set up apache the same way, to allow only 192.168 ip's but i guess it doesn't work that way in apache for connections coming though vpn? 2 out of our 4 VPN connections are not static IP's, so the 2 that are I just add that ip to the allow list and that worked.But i don't think we should HAVE to get static ips for the other 2, that's one of the benefits of using VPN, especially if our old windows server didnt need it.Is there any way for apache to see the clients ip address for access or is there something somewhere else that needs changed for this?

I can access dirac.org from inside my network; I can't access it from outside my home network. Apache is running on a Ubuntu box named "satan": 192.168.0.2 and I'm testing it from a MS Windows machine named "lucifer": 192.168.0.3. My ISP is optimum online, which does not filter port 80.
0. router
The router is a Netgear WNDR3700. All computers on my LAN receive their IP addresses via DHCP, but I've reserved all the IP addresses, so they are essentially static (satan is always 192.168.0.2, lucifer is always 192.168.0.3, etc). The router is set up to pass packets destined for port 80 to satan (192.168.0.2), which is where Apache runs.
1. tcpdump
Using tcpdump when accessing dirac.org from within the LAN (this is what works):
# tcpdump -i eth0 host ool-18bda2d2.dyn.optonline.net and tcp port 80
ool-18bda2d2.dyn.optonline.net.2826 > satan.www: Flags [S], seq 3934453911, win 65535, options [mss 1460,nop,nop,sackOK], length 0

I'm having a problem when I try to connect to my apache2 server from any client in my network using the .local address with the firewall on. I opened the port 5353 UDP but I still can't connect. The only way I can connect is disabling the firewall which I don't like to do on the server. What I'm doing wrong?

I am running an apache server thru webmin, on a 8.04 install. Attempting to install awstats I have realized that access.log stopped writing some months ago. Went back thru the error logs and found I had deleted the virtual server, and started a new one. Everything else works fine, it never even occurred to me that logging would not also be restarted. I would just like to get it going again, any clues???

I have a host system which is running Ubuntu and a guest system which is running Debian_squeeze on qemu VM. I need to send created traffic from Ubunto to Apache2 web server which is running on Debian. I made a bridge, and I can access internet from Debian, but this access is limited! I can just open some URLs not all of them! My question is how I can access the webserver from ubuntu?

I happened to be looking at my Apache-2.2.8 log on an Ubuntu LTS 8.04.4 system, and noticed a few lines like this:
Code:
61.160.212.242 - - [06/Mar/2010:07:04:41 -0800] "GET http://218.30.115.246/ HTTP/1.1" 200 295 "-" "-"
61.160.212.242 - - [06/Mar/2010:07:05:29 -0800] "GET http://218.30.115.246/ HTTP/1.1" 200 295 "-" "-"
xxx.xxx.xxx.xxx - - [06/Mar/2010:07:56:15 -0800] "GET http://218.30.115.246/ HTTP/1.1" 400 290 "-" "-"
(The third line is me telnetting to the server and trying to issue the same request. Note that I got a 400 error response, while the guy coming from 61.160.212.242 got 200s. Also, if you just open the http://218.30.114.246/ URL, you get back "hello" (nothing else, just 5 characters). I'm presently putting together a bootable CD with chkrootkit to run on the machine. (I found a thread that mentioned in passing that this was related to PHP, which I have running on that Apache server, but my Google-fu isn't strong enough to track down the original thread.) (After checking with chkrootkit: nothing unusual found.)

I'm trying to set up a small Intranet system to run OpenERP or similar using browser-based clients. I have an Ubuntu machine running 10.04 desktop edition to act as a temporary/testing server until we set up a proper, dedicated machine with 10.04 server edition. I have installed Apache2 from the repos and it is up and running fine - locally. That is the problem, I can't access the server from other machines on the LAN. Ping works, btw. So I've been reading tutorials and howtos for the past week, but for the life of me, I can't find what I'm doing wrong. The standard Apache setup seems to be made to "just work", so although I've looked at the various configuration files mentioned in the tutorials, I haven't actually changed anything.

I have recently installed a LAMP server on Ubuntu 10.4 nd I would like to have the /var/www folder writeable and accessible by my other computers on the LAN. I know I have to install Samba but how do I configure it so I can map network drives to the WWW folder and allow read and write access?

I came back to see on the screen a message requesting remote desktop control. So I said no and went into remote desktop and said never allow connection. I had recently hosted a PHP app on the home pc for testing purposes using apache. Here are some of the last logs entries:

I have a Name-based virtualhost website in Apache, what i want to do is to disable direct ip access to the site and allow only through web address (www.mysite.com, and not through xxx.xxx.xxx.xxx). Or at least show a default page / not found page
I presume this can be acomplished with Mod_Rewrite and .htaccess but i just wanted to know if there is a more global option for this
I have googled this a lot but i can only find posts related to ip host restriction rules, which is not what i want

I have web server apache on linux Centos. I can access it successfully by typing on the address bar http://localhost, 127.0.0.1 or 192.168.0.150 from the local computer server and the site loads normally with graphic. When I access the site from another computer in the same local network, I don't get the correct website. I see the site like html as text not graphic. Please see below text file output from the browser: Also I can only access the site by typing 192.168.0.150 IP address in the address bar. When I type http://localhost or 127.0.0.1, the site does not come up. Do you see what I did wrong? How can I fix this problem.

I have 3 ips on the machine 10.0.1.30, 10.0.1.37, 10.0.1.38. .30 is the main ip 10/100 the rest are 10,100,1000 ports. I can only access Apache 2.2 over .37 or .38 but not .30

I am new to web server support. I have a request from my management to modify the logging slightly. Effectively I need to redirect a custom string from our http response into the apache access logs. When a user navigates to our site they receive a "dye" number that is associated with them. This number follows them to whatever cluster they are directed too. The string is formatted as such, com-company-dye: d0a2#6dfce. I need that that header dye to appear in the access logs so we can use that dye number as a key for troubleshooting issues though out our various monitoring systems.

I am running a syslogd on my ubuntu 10.10 system. I have a apache2 server on the same machine. I have configured my apache2.conf file to send the error logs to the local syslog server.
The config is as under :-
LogLevel notice
ErrorLog syslog:local1
I have also configured the /etc/syslog.conf as under :-
local1.info /var/log/apache2/error_logs
I have created a file in the /var/log/apache2 dir with the ownerships and permissions as under:-
-rwxrwxrwx 1 syslog adm 77 2011-08-11 18:14 /var/log/apache2/error_logs
Next I restarted the sysklogd and apache2 servers with a service command as under:-
sudo service sysklogd restart
sudo service apache2 restart
I thereafter observed the /var/log/apache2/error_logs file and found the entries for apache2 closing down and coming up as under:-
Aug 11 18:14:14 cc apache2[4940]: [notice] caught SIGTERM, shutting down
Aug 11 18:14:19 cc apache2[5282]: [notice] ModSecurity for Apache/2.5.12 [URL] configured.
Aug 11 18:14:19 cc apache2[5282]: [notice] Original server signature: Apache/2.2.16 (Ubuntu) mod_ssl/2.2.16 OpenSSL/0.9.8o
Aug 11 18:14:20 cc apache2[5285]: [notice] Apache/2.2.16 (Ubuntu) mod_ssl/2.2.16 OpenSSL/0.9.8o Microsoft-IIS/5.0 configured -- resuming normal operations
Now the problem is I donot get any other messages thereafter. So it is hardly useful. How can I increase the logged messages from apache. I tried the facility:
local1.*
Then restarted the sysklogd and apache2, but the contents of the /var/log/error_logs file remained similar. Next, I followed the link. I created the perl script for recording access logs of apache2. I then restarted the apache2 and sysklogd. when I opened my website from a browser, the access log did not work. I think I am getting something wrong with the facility value , in apache2.conf it is ErrorLog syslog:local1 ! but the script is suggesting that it should be local2 in the line 4
openlog('apache','cons','pid','local2');
I therefore changed the script to local1 in above line. But still no access log?

I have a fresh fedora 13 install, I managed to browse and setup my phpadmin.....and browse everthing locally. I can not browse the web site from any other machine in my network. All my machines get their IPs from my dhcp (192.168.1.0).I googled and read a thread in this forum, I understood it might be due to SELINUX. I disabled it, rebooted, still have the same behavior, browse my apache locally but not from other machines. I did a telnet from one of my machines using the IP as followstelnet 192.168.1.11 80got the following onnecting To 192.168.1.11...Could not open connection to the host, on port 80: Connect failed.I checked error-log and access_log file, found no hint. I think it should be something related to some fedora systemor firewall or selinux config that is not allowing access to it.

I am looking for the best way to set up permissions in the following situation. I have a web server set up on debian. I have different web sites in /var/www. Each web has a group of developers who each have system users and ssh access to the server. For example i have a web site in /var/www/example.com and a group of developers in group exampledev. I need all the users in exampledev plus the apache user (www-data) to have read write and execute permissions on all the content of the web site. I can give the group exampledev these permissions without a problem. The problem is that when they modify or create new files (they either connect via ssh o sftp which is the same right?) they are created with their user and group rather than exampledev. Am i going down the wrong path? This must be a common situation but i haven't found the solution.

We have Apache installed on CentOS 5.3 in our laboratory. Indeed the server is running fine for almost two years since it is actually the first CentOS 5 that was released just regularly updated. Now, most of our applications are custom made PHP applications and until now we somehow managed to avoid using PHP to fetch files that are on the internet itself. But now we are desperate because we need to allow PHP to fetch files through Apache but it seems as if Apache is not allowed to make a connection to the outer world. Additionally we use a proxy server to connect to the outer world so right at the beginning http_proxy is used to set that environmental variable. And for the root user it all works fine after that but it seems as if the apache user is not allowed to access the internet. Just to make a remark our web server can be accessed from the outer world so its a one way street for now.
