When I attempt to install a new hardware system over the wire via NFS I get the following error:"unable ro retrieve http://192.168.0.1//install/images/stage2.img."The httpd.conf file is configured to use /var/www/html as the root. I have placed the installation files in /var/www/html/install. In the http install screen I enter the following information:Web site name: 192.168.0.101CentOS directory: installI have tried many different variations in these two entires, but the error always is the samw: the installation script searches for an address which has an extra / character interposed between the server IP address and the directory path entered in the next line.
I've been attempting to setup PXE/HTTP network installs so we can better handle deployments for new systems. I have a test CentOS 5.4 VM running, and another test VM that I want to deploy 5.4 to. TFTP, DHCP are all working correctly. Apache 2.2.3 config "seems" OK. When I kick off the VM which I will install to, DHCP discovery and IP allocation works, the TFTP server is found, I am presented with a menu option of OS selection.
I choose #1, for my 5.4 but then it immediately tells me: "Invalid or corrupt kernel image"
/var/log/messages doesnt show anything other than the DHCP OFFER/ACK process and that TFTP client doesn't accept options /var/log/httpd/error_log doesnt show anything either Not sure where else to look for diagnosis. My Apache config directory: /var/www/html/CentOS
My Apache DocumentRoot: /var/www/html/CentOS Directives: <Directory "/var/www/html/CentOS"> AllowOverride None Options None Order allow,deny Allow from all </Directory>
Forgot to add this line from my pxelinux.cfg/default file: label 1 kernel 5.4/vmlinuz append initrd=5.4/initrd.img ramdisk_size=16000 method=http:/10.37.129.3/CentOS ip=dhcp
(I think I have found my problem.. 5.4 was in the TFTPBOOT directory, but now that I'm using HTTP, I changed this to be: kernel CentOS/vmlinuz and append initrd=CentOS/initrd.img) -- question is, will just changing this work?
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 am having a problem with 5.4 that I did not have with 4.5. The problem happens only sometimes but in specific instances. Basically a summary of the problem is that certain network transactions timeout. The specific instances are with wget, rpm, http. The problem usually, but not always, occurs with pptp stuff. (NOT running pptp but getting pptp stuff). For instance, the following command, which finishes in seconds on non-5.4 OS's: wget [URL] downloads about 20% then gets stuck. About 5 minutes later it downloads another 20% and then gets stuck, etc. The same thing with rpm: rpm -ivh [URL] waits about 3 minutes and then gives an error. I think it does the same thing as the wget but wget will keep trying, while rpm gives up. The error from rpm: Retrieving [URL] ..five minutes later:
I can wget the above as I mentioned before and install it that way. Before I do it, yum works fine. Afterwards, yum exhibits the same behavior of timing out (because it is using the pptp repository). Also visiting the pptp web site from Firefox times out on certain pages. I originally thought it was some problem with the pptp site, but I notice that log into hotmail.com. Does the same thin (fine on other operating systems). A view with Wireshark on the wget (pptp) shows the my machine receiving a reassembled TCPPDU from 216.34.181.96 (Sourceforge), sending an ack, receiving a reassembled PDU, sending an ack, receiving, sending followed by the 5 minutes or whatever of nothing. Then sourceforge sends an RST and a SYN and the process is repeated.
When I put the machine directly on an AT&T IP connection (12.147.X.Y) everything worked fine. Same with Comcast on a direct link. The times I am having problems is when our router is hooked up to a Comcast IP (70.88.X.Y) and assigns 192.168.5.X addresses to our machines. So when I was doing the above from 192.168.5.27 going through the router through Comcast is when I had the problem. So it is probably something with the router, but it is hard to figure out since CentOS 4.5 and Fedora do not exhibit this behavior, nor does 5.4 on most sites (mail.yahoo.com for instance). I did verify, at least from what I could, that ICMP type 3 and 4 are not being blocked. If they were, the same problem would happen on other op systems. And I was able to ping, albeit just locally, but we looked at the router settings and ping was not blocked.
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 have a problem installing CentOS 5.5 over lan. I set up a dhcp3 server and it works, client got an ip. I set up a tftpd-hpa server and it works, client can boot the install image of CentOS 5.5 I set up an apache server and it seems to be impossible... In the installation marathon I clicked through the menu to the choice of the web server where my installation files are available. I enter the ip 192.168.138.1 and the path CentOS-5.5 and CentOS tells me "Unable to retrieve http://192.168.138.1//CentOS-5.5/images/stage2.img" . Thats right because the two slashes are not right. Where the hell come the two slashes from???
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.
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.
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:
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 ??
I installed CentOS. NetworkManager successfully installed and launched. I can ping any IP from terminal but I can't open any site in browser except 127.0.0.1 I can't open IP of the modem 192.168.1.1 in browser also.
I installed CentOS 5.3 on my Shuttle SS-31T with SiS 190 network adapter. While booting the message "Bringing up eth 0 [ OK ]" appears. After booting it isn't possible to surf to an internet location (p.a. www.google.com). It's also impossible to ping other machines in the network. After typing ifconfig everything seems to be ok.

In my workplace, I can't update Centos using http protocol, but, it's possible with ftp (I tried with Debian and it's work). How to configure the repositories in Centos 5.5, to download the packages by FTP?
My ISP has a bad habit of killing nearly all sustained FTP transfers (reset packet to my router and the remote host) and I need to install CentOS 5.5 on an older pc that doesn't have a DVD drive. My solution would be to (temporarily) turn on IIS on my laptop and extract the contents of the DVD to the ftp dir, but do I simply just drop everything in there with the same directory structure as the DVD or is there a particular way I should set up the directories?
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?

I'm trying to set up my CentOS 5 box as a gateway for my home network.I've set up dhcp on my internet interface (eth0) and dhcpd on my LAN interface (eth1).I can browse the internet from my CentOS 5 box.I can ping the CentOS 5 box from my LAN.However, I can't browse the internet from my LAN.I've enabled IP forwarding in /etc/sysctl.conf and I've disabled my firewall. I've saved these changes and rebooted. Again, no internet browsing from my LAN.
I can't get the CentOS version of pptpd to work. I have a Debian 6 one with the exact same setup that does work. The required port is open according to various external port checking websites. It's giving me random errors when trying to connect, including 800, 809, 619. This is what I did so far;
Step 1. Installing pptpd the pptpd is the daemon that runs the pptp server.
To install this:
Step2. Next you will need to modify the pptpd.conf
Step 3. The vpn server is now configured and now you must setup authenticated users:
Step 4. When pptpd was installed it started automatically so we will need to restart it to apply the changes:
Now, if you would like to add internet access over this vpn, you can do this:
And find the line for ipv4 forwarding and make sure it = 1:

I am setting up a new server with 2 nics installed. Nic0 goes to the firewall and nic1 goes to the internal engineering network.
Problem is Ip forwarding is not working!
Particulars: Server Name - slick Firewall Name - gateone engineering node - crooked
Routing on slick:
From crooked ( which is inside the server (slick) with an ip address of xx.xx.221.249 the only way I can ping or anything outside of the firewall ( gateone) is to turn on IPtables with this configuration:
I don't want to use IPtables. I need the ip forwarding to work.

Would like to seek your support and idea about the having 2 IP addresses bind to my server.I am using a Dell Server coming with 2 Gigabit Ethernet ports -- eth0 and eth1.After CentOS 5.4 installation, if we assign 2 IP addresses 192.168.1.1 and 192.168.1.2(both in the same subnet - 255.255.255.0) to the 2 NIC. The default gateway is 192.168.1.254.We found the following phenomenon:1. If we unplug the cable connecting eth0, eth1 will be disconnected as well.2. The connection to the server, like SSH, FTP, experience frequently disconnection.My questions:1. If we want to connect both cables to the 2 ports, how can we make them independent and actas normal? That means both ports are functioning independently.2. Is the any build in function in CentOS that can bind 2 NIC as 1?
So I just did a fresh install of CentOS 5.3 and ran an initial update how ever I cannot get the network manager to start. I found this page on the wiki - [URL]? highlight=(networkmanager) But when I try to run chkconfig NetworkManager on
