I have task to do configure a two httpd service in a same linux machine using iptables.
For example: Run primary httpd instance on 80 and 443 port if primary instance is down switch to second instance running on 8080 and 4443 this can be achieved using iptables.
For the first time in installed and configured centos-ds from this HowTos and from the manuals.It is running nicely but disabled my httpd.Is it not possible to run directory service and httpd in the same machine

I have reviewed the HowTo wiki on Setting up an SSL secured Webserver with CentOS [URL], and have successfully set up my server.
We are using the conditional <IfDefine SSL> tags around the <VirtualHost _default_:443> section. I wanted to do this because we are deploying a standard <VirtualHost> section that is appended to the httpd.conf file for several Apache versions on several OS's, and this makes maintenance much easier. Sometimes the server will be configured with SSL support, and sometimes not, depending on certain functions of our application that the end user will require and determine. Our application then determines which mode the server should be run in depending on these functions, what OS is being run, what version of Apache is being run, etc, and starts the httpd server in the appropriate mode. For CentOS 5 with Apache 2.2, if the application indicates SSL is required (and we expect the server to be configured appropriately), then we do the following:
/usr/sbin/apachectl -D SSL -k start
Has anyone noticed that when using NameVirtualHost's in apache that the service httpd restart command is broken?Also it seems system-config-bind has glitches too.

I can start this from the command line and it shows no errors.
httpd -t --- syntax ok.
no entry in the httpd error logs.
chkconfig reports it as on.
service --status-all shows this --

The httpd.service file does not exist on the system. Where can I get a copy?
I configured httpd.conf. With ip, port 80 and specified the document path correctly. But service httpd restart shows httpd stop fail, httpd start fail.

View 2 Replies View RelatedAlright, so I upgraded my old fedora 10 server to Fedora 11 with a netinstall CD, but now service httpd restart is broken. I already had to delete the old config file and reinstall apache, but now I can't restart it. I can kill it and then start it manually, but it never stops the running instance and fails to bind the port. I know it's because /var/run/httpd/htpd.pid is in the wrong place, which would be /var/run/httpd.pid, but do I have to make a symlink every time I want to restart it? I edited all the config files to point to the right place, but the system does not honor them. What do I do?

I am using CentOS 5.6 with Apache 2.2.17. The Apache was compiled from source using RPM build to comply with PCI requirements. Also Plesk 9.3 is used as a control panel, but other than the config files the Apache is pretty standard. When the httpd is started, there are no errors reported in /var/log/messages or in the error_log, and the httpd starts, shows up in ps and the pid file exists in /var/run/httpd.pid.
However when you check the status 'service httpd status' you get 'httpd dead but subsys locked'. You can add websites normally, and the proper config files are generated so I am pretty sure this isn't a control panel issue as I have other servers running the same control panel and Apache 2.2.16 compiled and installed the same way as the 2.2.17 and there are no problems.
I need to change the some configuration in httpd.conf file with out affect any current status of http service.

This is my first use of Ubuntu, but I have previous decent experience on Centos & Mandriva. I've just installed Natty 11.04 on a box that was running a mandriva 2010 - and the network is acting quite strange. When I define a static IP for eth0 through the gui, along with route & dns, it sort of works: ssh is fine, vnc too. However, I have an asterisk running on the box, and it is wild: some packets get lost in the box.
An ngrep shows the packets reaching the interface, but they dont show in asterisk !!! I've done a ufw disable, iptables is empty (why cant I service iptable restart btw ?). ip route list show decent routes (eth0 default); When I switch to DHCP, it is better, but unstable... If i plug a wifi usb stick, it seems to be better... Is there some known issues that could explain this behaviour ?

View 4 Replies View RelatedI have a machine that is like a firewall, I use iptables to route traffic through it, to the router. For ex
Host1 -> Middleman -> gateway -> Internet
Internet -> gateway -> middleman -> Host1
I have this working using these rules:
Code:
# 192.168.0.6 = host
# 192.168.0.8 = middleman
iptables -A PREROUTING -t nat -d 192.168.0.6/32 -j DNAT --to 192.168.0.8
iptables -A POSTROUTING -t nat -d 192.168.0.8/32 -j SNAT --to 192.168.0.6
On the middleman machine when I analyse the traffic using Wireshark, I can only see the outbound traffic, I don't see any traffic from gateway->host only host-gateway The traffic must be passing through both ways because the host has Internet access. How can I modify the iptables rules to see the traffic both ways?
whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?
View 1 Replies View RelatedI want to do port mapping on a linux machine using iptables.I have a service listeneing on port 2000 udp and I want to add iptables rule, which will map incoming packets on port 2001 to port 2000, so that service will accept the connections.The idea is that I don't want to change the default port for the service, but to make internal port redirection from (2001 to 2000), so the default service port will be filtered by iptables, and the other port will be open to the outside. The internet host connects to the linux machine on port 2001. The linux machine change destiation port from 2001 to 2000 and the service (on the same machine) process the packets and accepts the connection.I tried adding the following to my iptables rules, but it didn't work out:
$IPTABLES -A FORWARD -p udp --destination-port 2001 -j ACCEPT
$IPTABLES -t nat -A PREROUTING -i eth0 -p udp --dport 2001 -j REDIRECT --to-port 2000
I had been running my SMTP server with WINE, as the SMTP server software is a Windows-based program (MERCURY), but I cracked the shits with WINE and removed it. Now I am running my SMTP server in a Windows virtual machine.This virtual machine has a different IP address from my host machine, so what I need is for my computer (the host) to redirect incoming traffic on port 25 to the virtual machine at 192.168.56.101 on port 2525.Can someone please help me with it? I think its done with iptables.
View 1 Replies View RelatedI've got the following two subnets.
Code:
Subnet 1: 10.1.0.0/24
Subnet 2: 172.16.0.0/24
A machine in subnet 1 is natted to a static address in subnet 2. For instance 10.1.0.10 is natted to 172.16.0.10.
I have achieved this with the following iptables rule. (in addition to enabling forwarding)
Code:
iptables -t nat -A POSTROUTING -s 10.1.0.10 -j SNAT --to 172.16.0.10
So far this works perfectly. What I want to do now is to add another rule that only nats the machine in case it is NOT accessing subnet 1.
In other words, when this machine accesses any other machine in subnet 1, it should show up as 10.1.0.10. Whenever it accesses subnet 2 of anything else, it should appear as 172.16.0.10.
