On my 10.04 LTS Ubuntu Server installation, apache2 doesn't bind to ipv4. It does bind to ipv6. I didn't notice this at first, because from my home connection I could visit the webpages without trouble. I noticed it running netstats -ta:
setting up NAT and firewalling for both IPv4 and IPv6. The machine is headless, so everything must be configured via CLI. I've done all IPv4 firewall configuration writing iptables rules in a bash script so far
messages appear in syslog each day. Each URL has from 2 - 6 attempts at various ipv6 addresses. My question is why is bind9 trying to resolve ipv6 addresses? I have done nothing to enable or disable ipv6 and thought that if not explicitly enabled I would not have to be concerned with it.
I'm running a native dual-stack (ipv4 & ipv6) dsl connection.So, I've been adding firewall rules, cleaning up unwanted processes, etc to tighten security.I'm left with only 3 processes that are listening to ports. mysql, ipp & ssh.Still not quite sure I need mysql. I run Amarok but without using a database, so I don't actually use sql for anything that I'm aware of.Anyway, my question is;Is it possible to make any any of these processes listen to ipv4 only or ipv6 only? Is there a distinction there at all?
Example- ssh is currently listening to port 22 on both tcp & tcp6. I do all my ssh connections using 'ssh -6', so, Can I make ssh listen to tcp6 only, or ignore tcp ?
How do I assign IPv4 and IPv6 static addresses permanently in OpenSUSE 11.2? Currently I am only able to assign either IPv4 or IPv6 static address not both. I cannot find even the interfaces file(/etc/sysconfig/network/interfaces).
I've installed mailman on 9.10, using apt-get, have apache2 setup already. However I'm getting 403 forbidden issues when trying to access [URL] I may have mucked something up as initially i jumped straight in and created a virtualhost and played around with the URL redirects. but as far as I can see, it's back to its default and it's still not working... When I try to access the page, in my apache error.log, i get this:
[Wed Mar 24 02:36:37 2010] [error] [client 192.168.1.1] attempt to invoke directory as script: /usr/lib/cgi-bin/mailman/
I've tried check_perms, it does give this error:
root@babel:/etc/apache2# check_perms /var/lib/mailman/templates bad group (has: root, expected list) /var/lib/mailman/bin bad group (has: root, expected list) /var/lib/mailman/cgi-bin bad group (has: root, expected list)
I have several sites running on a local server. Currently, they're all running on port 80. I need one particular site (and ONLY that site) to also accept connections on port 81.
If I browse to the server IP x.x.x.x:80 directly, Apache's behaviour of showing the default site should work as usual. But, if I browse to IP x.x.x.x:81, it should show a different site (the one that should be accepting both :80 and :81). This part is very important.
I was hoping something like the following would work, but it didn't Currently x.x.x.x:81 still shows what I've called myport80defaultsite.com below.
I installed it the standard way using emerge/portage, but it fails to start:
alpha skyer # /etc/init.d/apache2 start * Caching service dependencies ... [ ok ] * Starting apache2 ... apache2: apr_sockaddr_info_get() failed for alpha apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName [ !! ] * ERROR: apache2 failed to start
I'm used to have Apache unable to find pc's FQDN, as I don't set it, and it works without it.
[Sat Jul 23 06:41:12 2011] [alert] (EAI 2)Name or service not known: mod_unique_id: unable to find IPv4 address of "alpha"
Computer has IPv4 address set. I suspect that the nature of the problem is in the fact, that alpha has two network interfaces (it is used as router also). I've checked Apache conf files, but didn't find any meaningful directives to set interface or something similar.
I am trying to configure Apache on my server to work with ssl, but everytime I visit my site, I get the following message in my browser: SSL connection error. Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.
Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. Just some background on the situation: I am using Ubuntu 10.04 desktop edition. I installed apache by installing zend server (it installed apache automatically). I then installed openssl. Non-https pages work fine on the site. I tried getting trial certificates from multiple certificate sites but nothing is working (same error). I was previously hosting my site on another server on which ssl worked just fine. I also tried using the key and crt file from that server, but I got the same error. The domain name and IP are still the same though. My SSLCertificateFile and SSLCertificateKeyFile are pointing to the correct directory and files.
I'm using ubuntu 9.04, I want to design webpages in PHP for that I installed apache 2 on my machine. I'm using my mobile to connect to the internet when ever the mobile is connected and the wired connection established the server running properly. But when the wired connection disconnected my browser page didn't show the localhost home. How can I configure the apache on my machine.
I'm forging a gateway server, We have 2 Internet connection that goes to a load balancer router, and goes to my centos server and from our server goes to a switch for Internet distribution or routing.
OS-CentOS 5.5 [root@server etc]# uname -srio Linux 2.6.18-194.el5 i386 GNU/Linux
My eth0 and eth1 has the following configuration and IP
[root@server etc]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] DEVICE=eth0 BOOTPROTO=none
Disabling IPv4 packet forwarding but i already changed it to 1 at sysctl.conf One of the online forum says i need to configure the named.conf deleted some and run it(named.conf) and successful but still when I run network service I still get the :"Disabling IPv4 packet forwarding: net.ipv4.ip_forward = 0" The network is getting the IP range but it doesnt get any Internet connection.
I've installed webdav on my server and I can access it fine through cadaver. However, when I try to access it via nautilus, I get Forbidden. It is NOT secured (SSL). When I try to access it via firefox, I get an error since I DO NOT have "Options Indexes" in my apache config file. If I add this option in, then I can browse the root direction and webdav folder via firefox, but still not from nautilus. what other information you need. I've googled and searched the forums for awhile, but not "solutions" I found have worked for me. I want the webdav folder to just be a single folder within the direction, so this is how I have my config file setup:
As a side-note...when I included "Option Indexes", it allowed me to view the passwd.dav file from firefox!That doesn't seem very good...
I installed apache on my local machine to test my sites. I have one problem:I created a new site configuration in /etc/apache2/sites-available and enabled it. The problem is that cgi is not working, it just prints the content of the files. (The default location for cgi, /usr/lib/cgi-bin works without problem.)Here is the content of the site configuration file:
I have Apache Server working online under Fedora Core 6. But before I installed and configured everything, I've been testing in Fedora 12. The problem surges here, when I start the httpd service, every supuse 404 action on a web browser, takes me to localhost. I mean, if I enter google.com, no error, just goes to localhost, http://asdasd, no error, gives back localhost. I used to ignore the problem 'cause I thought it was a problem on my apache, but when I installed the Server on the Fedora Core 6 machine, I found that I have the same problem there. Of course, it only occurs when I am browsing through the same machine that has httpd started. Does anyone know how to change that??
I want to start to play with "homemade" kernels. (To get some experiences in this subject). I want to do this step-by-step. I have already read a lot about this. I have a Fedora 10 running. So I want to start with this. I have read that there is a "special" way to create a kernel for Fedora. [URL] OK. I understand this +/-. When you build a new kernel with an other version number, you have to rebuild all the modules with this new kernelversion, and you have to install these also.
But : I want to start with modify only some parameters in my kernel config. Do I need to rebuild and re-install the modules also? Will it not be enough to rebuild only the kernel? (vmlinuz) Where can I find some information about the options I can disable in my kernel to speedup my system? (boot process ed). I want to suppress the loading of unneeded modules. I want to understand the options in menuconfig (and there are a lot of options ! ! )
After doing this I rebooted my server (a few days later). After rebooting I had no ipv4. I tried statically assigning IP addresses to no avail. Ran ifconfig eth0 down/up which got me nowhere. Eventually decided to ask "Okay, what changed". Started installing packages that were autoremoved. Had to install from the apt cache using dpkg. First one I tried was sendmail-base. Then did ifconfig eth0 down/up, which gave me networking back.
I have checked the dependencies for sendmail-base and I see nothing that would relate to networking, so I'm really confused on why this happened. I had backups of the server so I went a week back and noticed sendmail-base was installed at that time. So I went a day back, where sendmail-base wasn't installed, and installed it. Sure enough it brought back networking. I'm just stating this because it is more proof that sendmail-base was the missing component.
I have an OpenVPN(10.04.2 LTS) server running in bridge (TAP) mode. Its sitting behind a router and then a cable modem. The VPN works perfectly but I have a security concern. In order to allow the VPN clients to connect to the internet, I had to enable IPv4 forwarding on the server. Is this is a security hole? Can a hacker access my servers connection from the internet (without authenticating with OpenVPN) and access my network. Can someone use Ipv4 forwarding to access my LAN network from the WAN
I used this command to enable ipv4 forwarding echo 1 > /proc/sys/net/ipv4/ip_forward
Without IPv4 forwarding my VPN clients can only access my LAN and router, but they cannot reach my modem or the internet.
Is there a way to access today the openSUSE servers via IPv4? My ISP does not support ipv6, nor my router, and I can't install software right now in openSUSE, because it wants to access te servers via IPv6.
If would be grat to have the download.opensuse.org ipv4 address.
I really need to install some packages, they are required for my school project.
