Debian Configuration :: Bridge Network - Two Virtual Hosts?
Apr 1, 2011
I have a debian squeeze box with dual NICs that I'm trying to configure with two virtual hosts. I'd like to have one of these machines act as a router for the 2nd NIC so I can plug in a switch and have a separate subnet.
Something like:
- Openwrt router 192.168.1.1 (firewall/vpn/stats for 192.168.1.0/24 domain)
- KVM machine with 2 NICs (192.168.1.2)
- Virtual machine #1 has a fixed IP of 192.168.1.3 (virtual nic)
- Virtual machine #2 has a fixed IP of 192.168.1.4 (virtual nic) but also controls the 2nd nic and routes 192.168.80.0/24
I'd like to use the 192.168.80.0/24 network for testing equipment without poisoning my existing network.

I'm attempting to use a network bridge to connect my virtual machine, like so:
[Code]...
The issue is that when I type the following command, I get the further following horrible error message that doesn't seem to really point me to anywhere and I can't seem to find any relevant information to my problem on the web:
root@darkstacks:~# qemu-system-i386 -hda test.img -m 128 -curses -net nic -net tap,ifname=tap0 warning: could not configure /dev/net/tun: no virtual network emulation
Does anyone have any idea what I need to do here? My processor does not have the vmx flag, as it's a 2.4GHz P4. I don't know if that might have something to do with it.

I'm having trouble implementing SSL on a AvantFax login screen. I've created the the certificates and keys and have them stored in /etc/apache2/ssl and I'm sort of stuck now. I've been following a guide but any changes to the conf files leads to errors. The system I'm using is Debian 5.0

I don't know if this should be a followup to my prior topic [URL] ....
Each of the pieces I've installed all have an "Alias" directive in the conf file to link the directory where they live to be present on my server. For instance, DotClear lives in /usr/share/dotclear/web/ and there is a directive
Code: Select allAlias /dotclear /usr/share/dotclear/web
that directs http://myserver/dotclear to that site.
Now, I've set up VirtualHost entries for my DotClear and Owncloud with their own hostnames.
Code: Select all<VirtualHost *:443>
ServerName myowndotclear.com
ServerAlias www.myowndotclear.com
DocumentRoot /usr/share/dotclear/web
[Code] ....
Something similar for Owncloud.
The problem is when I go to [URL] ...., I get to my mythweb site.
This is not so good. So, for the sites that have their own hostnames, I removed the "Alias ..." directive. Of course, now I can't get to the hosts by going to the primary site which is probably fine, but I also still get my mythweb since that doesn't have it's own virtualhost entry.
This doesn't seem like correct behavior. Is there a better place to put the "Alias ..." directive so that it only works from one site and not all of them?
I am also thinking I should just link the directories into /var/www/html, but I'm not sure that's a better solution.

How to best manage both http and https pages on the same apache-server without conflicts. For example, if i have both 000-default.conf and 000-default-ssl.conf pointing to mydomain.com, and don't want users who visit mydomain.com without specifically type the https-prefix to be redirected to the https-page - how to handle users using browserplugins such as https-everywhere etc?
Another option would be to create a subdomain ssl.mudomain.com and have users who want to reach the ssl site to have to type ssl. I have tested several things with https everywhere enabled in my own browser, and it seems really hard to make this working the way i want, in one way or another i always end up getting redirected to the ssl-site automatically.
The reason i need this to work is because i run one site that i don't care much about SSL, that is the "official" part of that site, and i also host some things for friends and family on the SSL-part. This would not have been a problem if it wasn't that i use self-signed certificates for my ssl-site and the major user become afraid when a certificate-warning pops up in their browser and therefor leave the site.

I have two ethernet NIC's on my debian server. One built-in Realtek [eth0] (attached to internet), and a PCI Nvidia ethernet card [eth1] (attached to my Win7 netbook). I used this guide to setup the bridge: url. It worked when I was behind a router. But when I moved the computer in front of the router, to direct connect to the internet, the internet stopped functioning on any device that I plug into my Nvidia NIC. The name of my bridge is 'br0'. Does anyone know how to fix it, so I can route the internet to my second NIC?
My Win7 netbook displays this at an 'ipconfig' command:
Windows IP Configuration

Connection-specific DNS Suffix:
Link-local IPv6 Address.....: fe80::143e:4cab:f802:8611%12

My Debian interfaces file:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# Set up interfaces manually, avoiding conflicts with, e.g., network manager

I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.
Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:
(The WiFi is secured with WPA2 Enterprise)
Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
[code]....
The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?

I'm having an issue with setting up the virtual hosts on my web server. I have 2 virtual hosts (example1.com, example2.com). example1.com works but example2.com is sent to the index file of example1.com. I did some searching on google and it seems the problem might be with my /etc/hosts file.
First virtual host that the second is also directed to...in sites-available/sites-enabled (note port 80 is blocked by my isp so I use 8080)
Code:
Second virtual host file
Code:
And my hosts file
Code:
# The following lines are desirable for IPv6 capable hosts
Also I'm using a dyndns.org...would that make a difference?

I'm having issues with my GigE Marvell NIC. The problems have started recently. Anytime I push network bandwidth over ~9MB/s, I loose all network connectivity. Stopping the network, rmmod'ing and modprobe'ing the sky2 module and then starting the network again does not resolve the issue (even though eth0 dissapears and then comes back). The only non-standard configuration (as far as desktops go) in my network is that I use a bridge so a KVM virtual machine can be exposed directly to the network. I'm currently testing the problem to see if it exists outside of the bridge.

When I converted to OpenSUSE 11.2, and went through YaST HTTP Server Configuration, creating my virtual hosts under the Hosts tab, YaST combinedm all int ile,"/etc/apache2/vhosts.d/ip-based_vhosts.conf".I did google and read, [URL]for further assistance.I'd like each virtual host to have its own file under vhosts.d, and wondering why YaST did not do that.The file /etc/apache2/httpd.conf laid out the file structure, and all vhosts.d/*.conf files are included.Is there a way to tell YaST to create separate files for each vhost, or does the user have to manually do it?

I currently have an Apache Web Server running on Ubuntu 10.4 and I use a DynDNS service to make them accessible to the outside world via a domain and/or subdomain.
My configs currently look like this:
<VirtualHost *:80>
ServerAdmin <obscured>@<obscured>.com
ServerName <subdomain>.<obscured>.com
ServerAlias <subdomain>
[Code].....
This works fine from access outside of the network and all subdomains resolve to the correct directory.
The problem I am having is with accessing a subdomain over my internal network.
I can access the Web Server using the server's IP address: http://192.168.1.123/ but this always takes me to the same virtual host and I don't know how to distinguish between different virtual hosts (different subdomains).
Ideally I would like to access the same subdomains using http://<subdomain>/ where <subdomain> is the same as the subdomain attached to the external domain name.

I run a dedicated opensuse 11.1 server with apache (2.2.10-2.9.1) installed. This box has been running for nearly 2 years hosting several low traffic websites. I must admit that I did not give lots of love/attention to the machine over that period. It ran rock solid. The different websites each have their own associated user account and are stored in their own /home/name/public_html/ folder. It was setup through Webmin. Each domain name is also linked to a unique IP (the box has multiple available IPs), however this is configured at my domain provider. All in all a very simple and straightforward setup that never let me down most of the past decade.
Recently the sites on the machine were no longer responding. This happens each other year or so since I write my logfiles to a separate partition. Was df -h and indeed, partition was full. Removed logfiles manually, and while I was at it I decided it was time to run an online update (yast2 / online update that is). Rebooted machine after yast telling me to do so. Sites are no longer working. Can no longer login to webmin. Only thing what works is the 'root' webpage (/srv/www/htdocs folder), which makes me rather clueless as the other sites are just not responding at all, not even a timeout or error message.While I know that deleting logfiles manually is quite stupid, I've done it fore and not really ended up in trouble.
Hence my questions: does this sound familiar to anyone and do you mind to give me a clue about where exactly I should start to look. It's been ages since I actually administrated apache, so I might overlook the obvious. Long story short: any tips are very welcome about what I should check first, what config files might have been changedith the update, etc ...

I have got a debian (v3.16.7-ckt25-2) for server (without X). There is a br0 bridge connected to eth0 network device. It works fine when I start it manually by
Code: Select all# ifup br0 but I cannot start automatically at startup.
there was a missing line in /etc/network/interfaces:Code: Select allauto br0

apache virtual host to limit the concurrent connections of virtual hosts? Taking into account the host of each virtual user's home directory can also have more than one subdirectory, which should be restricted to a subdirectory. Is beyond the control of the operation of these sites in a subdirectory. Best local restrictions or limitations to the overall situation.

I'm trying to bridge connections between a wired and a wireless connection in one of my computers. I was told it was impossible due to low-level limitations in the wireless subsystem, but apparently theres a way if you somehow forward packets from one port to the other. Is there a way I can achieve this?

I want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.

I've successfully install kvm with private network (nat) up running. I want to switch the kvm network using bridge mode (or host-interface), but do not success. env: nic iwl4965/ kernel 2.6.27.8/ debian etch upgrade to lenny/ kvm 0.9.1/ hardware hp 6910p The doc I follow up is at [URL] The way how i set it up is to modify /etc/network/interfaces by adding following section to enable br0
Code:
allow-hotplug br0
iface br0 inet dhcp
bridge_ports wlan0
bridge_fd 9
[code]....
However, the problem is the guest os, which starts with -hda k1.img, can not access to the internet. Is there any step I miss? or it is because wireless does not support bridge (I've heard doc says that wireless does not support wireless bridge)?

I am trying something a bit tricky.Suppose there is a website URL...Now suppose when i open a file /var/www/ test.php which connects to the above website to gather some info and then allow me to further in the process, i want it to instead direct to a file say /var/www/test_done.php.How do i edit my hosts file for such a scenario? Is there any other better option than using a hosts file ?

I am trying to set up a network like this:
Internet <---> Router <---> Debian server <---> Windows PC
I want the server and PC to both have internet access, and I want to be able to forward ports from the router to the server. I know how to configure the server to give the PC internet access, but how would I assign an IP address to the server and give it internet access? I have used a very similar setup a few years ago, but I can't remember how to do this.

Now doing some research about performance of Linux switch. I'll start with basic structure of my system: PC1 is connected to PC2 - both have 1 NIC so not much to add.PC2 eth0 is divided in VLAN`s as far as maximum of 4094. Every VLAN has it's own switch (bridge). On PC1 when I run a test I just make VLAN/configure IP address and stream data to IP that's configured for that bridge on PC2.But now I want to add one more interface to each bridge, so I could stream from PC1 through bridge to Virtual interface (just an endpoint out of bridge). I could possibly add one more computer, physical interface to PC1 and make it work, but is there any way to make this work with virtual interfaces, like tun or something? Making just a simple tun interface and adding it to bridge, as you understand, doesn't do the trick, I need some kind of other endpoint that /virtually/ connects to tun interface. Maybe someone has made some kind of script or something? Using Iperf for my tests.

I don't know if I'm posting in the right box - I'm new to both Ubuntu and this forum so please bear with me. Thing is, I spent almost 2 days trying to find a web server that meets my likes. I tried like almost every well known web server, be it Apache, Lighttpd, Nginx, and Cherokee, one by one. For each I was successfully in getting PHP up and running, but was never able to configure the virtual hosts.
I'm 99.99% sure that I - for multiple times - followed correctly the online how-to's. Especially Cherokee, I did exactly the screencast (which is just 2 steps, as Cherokee has a GUI for virtual server setups). Strange enough, with each web server the virtual hosts thing never worked for me. I always received "Server not found" error. I tried with Firefox and Google Chrome. Currently I'm on an Ubuntu 9.10 (32bit) box - I reinstalled this one over the 64bit, to vain.
Don't know if it's a problem with my DNS, but I have another machine running Windows 7 with the same DHCP settings (means same DNS and IP range). Virtual hosts work fine there on an XAMPP installation.

I'm wondering if this is even possible before I start the learning curve with Ubuntu and apache virtual hosts.
I have a static external IP address that resolves to the various domain names I will be using. I have a web server inside my network with a private IP address and any http request to the firewall is forwarded to the webserver on the appropriate port. This setup works well when using the same web page/configuration for all of the domains.
Will it be possible to use named virtual hosts in this configuration, or will the NAT'ing interfere?

I'm running vanilla SuSE 11.1 on a vanilla server with Webmin 1.51 and Apache 2.2.
For a month now, I've been trying to get virtual hosts to work with Webmin without success. When I browse for the second site, I continually come up with the default host site.
just forget Webmin and modify the httpd.conf file directly. That defeats the purpose of trying to use Webmin.

Some time throughout the night last night eth0 stopped working entirely, I could not resolve dns or any thing. Oddly though eth0:1 and eth0:2 worked perfectly with a ping -c 10 -I eth0:2 xxx.xxx.xxx.xxx but still could not resolve domain names. My nameservers are good as i have tested them on my other machine. My setup had been working fine for quitte some time and i did not make any changes besides updating webpages, it is a server running Debian Lenny. Unfortunatly since eth0:1 was working for the most part i was trying to change the IP's in the config and accidentally killed the settings using webmin so I cant post to many details at the moment until my host for the dedicated gets my /etc/network/interfaces restored but in the meantime i have searched all over google to try to find an answer to the original problem but cannot so i would like to prepared for when the server is accessible again.

What is the (officially) proper way to configure Apache so that a given IP address can have two or more virtual host names, each going to different distinct configurations (e.g. with different DocumentRoot, Alias, etc), and also do this for the IP address so that it goes to a designated configuration rather than defaulting to the first or a random host name?
Apache documentation does not appear to address this. If so, it has it hidden in a non-obvious place.

it seems i have tried everything that everyone else is having issues with but nothing seems to fix mine. Possibilities:
1) EC2
2) Permissions on the files - I changed everything to the apache2 user "www-data" - no dice.
3) I am a dope...lets hope its that and one of you kind people point me to my issue.
