CentOS 5 Server :: Cannot Get Bind9 Internal View Served To Connecting Vpn Client.
Sep 25, 2010
I have a white slate centos 5.5 installation on a virtual box at Media Temple (one of their new VE servers). I am trying to create a development environment where I can have Bind9 serve up one set of zone files to me and other developers on the internal network and another set of zone files to external requests (ie... using the views feature). I would like to be able to develop for sites for which the dns is not yet pointed at my server. The network is created by having the VE server be an OpenVPN server, and connecting my client box to the server (my mac - 10.8.0.6 / my ve server 10.8.0.1).
I have the connections working fine, I have also been able to route all network traffic from my mac through the vpn to the server. For some reason, I cannot get the DNS server on the ve server to serve me an internal view zone file. When my vpn is on, I cannot ping or navigate to any web pages from my mac. I think this is because my ve server is not setup as a dhcp server and the ip tables are not setup to allow all internal requests to use the server to go get web pages.
I cannot view-ping anything else from my mac/client when on the vpn, I can successfully ping any website my ve is authoritative for. This tells me that my ping is obviously going over the vpn, and thus an internal request, but the external zone file is still served up. The following is my named config.
acl "lan_hosts" {
10.8.0.0/24;
127.0.0.1;
};

I'm running bind9 on Debian 6. I have a primary domain, 44kg.net, fully configured and working dynamically (the server also runs DHCPd and updates the DNS records properly).
[Code]....
To access my externally-facing website, which has a blog and a forum which are keyed to the external domain, I set up the domains in bind so they would resolve to the server's internal IP. This worked great for a few months, then inexplicably ceased working. I didn't touch anything, but it coincided with our router dropping its VLANs. I've moved the server to a different location and it's still not working properly. Whenever I try to lookup the external domains, I get SERVFAILs. This is annoying because the internal domain is fully working and I copied the basic settings.

We are having an odd apache issue. Certain files are not being served out.The files actually live in a remote DFS volume served off a windows system. They're mounted under /data/vizwx. There's a subfolder here called wx_intranet which has all the data.The Document root for this virtual host is /data/www/htdocs. There is a data/vizwxsubdirectory with a symlink named wx_intranet which points to /data/vizwx/wx_intranet .SELinux is completely disabled (not even permissive).
When a user requests a file from http://<host>/data/vizwx/wx_intranet/VizWx_14c.jpg no error is given to the browser. Firefox just shows the URL in question (I can't even view source). The <vhost>_access.log file shows: wx_access.log:172.16.1.16 - - [19/Feb/2009:15:30:16 +0000] "GET /data/vizwx/wx_intranet/VizWx_14c.jpg HTTP/1.1" 206 167791And there's nothing in the <vhost>_error.log, even after cranking the LogLevel up to info.
The permissions on the files in the share are slightly weird for reasons I don't fully understand, but they should work... the files are an effective 'chmod 3777 <file>' for all files in the mounted directory... that's with Sticky and SetGID bit set.What am I missing here? Oh, I also modified the Vhost's options from "Options all' to 'Options all -SymLinksIfOwnerMatch" to see if that was the problem... no dice.)CentOS v5.2, apache 2.2.3

If I use PHP or SFTP to delete or replace a file while it is being served will this cause the download to fail?If so is there anything I can do about this, the concern is for large files.

I have two DNS servers, one local and one remote, and I am trying to get them to talk to each other using views.
The problem I'm having is that the remote server can talk to the local one and receive zone files, but if I update the local server internal view, the remote doesn't receive the update. Here is my config:
Quote:
key "external" {
algorithm hmac-md5;
secret "xxxxx";
};
controls {
inet 127.0.0.1 allow { localhost; };

Before we use CentOS 4 and all work fine. We start x11vnc by ssh like root. And after this connect by client login in X screen. In CentOS 5 this way don't work. For connect we must login by local from keyboard, start x11vnc ssh by logined local user, and after this we may work, but can't change users.

I'd document here the way to get to eDesktop through linux (debian, ubuntu) at the University of West Florida (UWF), since they appear to only support Windows through their documentation on the University web site, and the link through Argus (the secure web site) doesn't work in Linux. This is sometimes needed to use the University resources (libraries and computer programs) from remote locations, and otherwise a google search is fruitless. I had to have a guy in the computer science department show me how to do it. This may apply for other Universities with similar setups. It was impossible for me to figure it out on my own, I had to go back to my old 9.04 partition to get the info...
1) Open Terminal Server Client (Applications>Internet>...)
2) Insert as follows:
Code:
Computer: eDesktop.uwf.edu
Protocol: RDP
User Name: YOUR USERNAME
[code]...
3) OPTIONAL BUT RECOMMENDED click Save As and save it as a quick connect so you don't have to refer to this again.
4) Flip through the other tabs and configure as desired, and click Connect!

i installed unix services for windows 3.5 on a windows xp pro box and it installed fine. I configured nfs on the debian box and exported the ip of the client computer and forwarded port 2049 correctly. I followed the instructions for setting up teh nfs client on windows. However whenever i go to tools->map network drive and type in the server-domain-name:/file-address it says it cannot connect?

trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface
auto lo
iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?

I use NFS to serve up my media files to all the other machines on my network. What I am seeing is if a client has the NFS directories mounted for a couple of hours, files will start "vanishing" from what is being served up. The files are still there on the server. The client can no longer see them. The only way to make them viewable to the client again is to unmount the directory on the client and then remount it.

My chief file server (Dell PE R300) died last week with a disk error, and because it serves the /usr/local and /home partitions via NFS to my ~60 desktops, nobody could do any work until I managed to rig up another server and pull data off the backups. I'm using RHEL 4.To avoid this in future my plan is to knock up a dual server solution with DRDB and Heartbeat.In the meantime, is there a better way to allow desktop users to carry on working as normal, without relying on the file server too much? i.e. something better than NFS but not LDAP (I don't want to implement this just yet as the organisation as a whole may do this in the future)? My users need to be able to access the same home area on any linux desktop managed by me.Also, to implement DRDB/Heartbeat, it might be best to have the home areas on an external array, is that right? Can anybody recommend some hardware?

Is there some way that I can use apache/iptables to serve both of my servers through the same basic domain? I'm not talking about VirtualHosts either, I don't believe ( despite the fact that's all I can find anything to read about on Google when searching for this ).
Anyway, the problem is that I have a TorrentFlux php torrent-client that I run so I can add stuff to the download when I'm not around. I don't want to put this on my regular webpage server because there's just not enough diskspace in that machine. On the other hand, I don't want to replace that server all-together because the other machine is my desktop and would not make a reliable host.
So my idea was that there could be some way to have the apache2 server on my dedicated server redirect a subdirectory in its webroot to the webroot of my desktop's TorrentFlux server, but over standard HTTP ports so that it is more like the server is serving up the content of my desktop server through its HTTP service, instead of simply redirecting.
The reason I want to do this is because so far I have to use the TorrentFlux server on a nonstandard port so my dedicated server can still host its own things on port 80, but I've been running into several situations where the browsers I want to use do not support the nonstandard port such as with some instances of IE or the browser on my BlackBerry.
Anyway, I'm not looking for a step by step or anything ( though it couldn't hurt ) but I just need some ideas on what I could search for to get some better ideas. There's probably some term for what I want to do I'm not even aware of that would help me greatly.
Runnining Ubuntu 7.04 and apache 2.2.4 along with shorewall 4.0 as my routing/firewall software.

I'd like to have anything that tries to send mail locally on my machine (including crontab reports for instance) to be handled by my ISP's smtp server instead of my machine acting like it's own SMTP server. I've spent around 15 hours trying to figure out how to do this and I keep either getting into things that I don't understand, or hitting brick walls (for instance, I found nullmailer, but after installing it, it seemed like it would only work on Unix) Is there an application like nullmailer which I can use as my MTA to forward all internal mail to a different SMTP?

I'm still learning my way around CentOS and linux in general... Using CentOS 5.4
BUT, I used the scripts from HowTo/Chroot Vsftpd and it did not work with the non-TLS script config, but the with TSL worked great. I wasn't sure where to put the vsftpd_virtualuser_config.tpl file but I copied it over when the script failed to find it... to where it was looking.
So I think it's working but my question is, TLS doesn't use port 21 but the script defaults to that port. I'm using FileZilla from an XP machine at work and I'm forwarding all the ports given in the HowTo. So I'm forcing the client to use TLS on port 21 but it hangs on the connection. If I use non TLS I get in but it tells me it requires TSL. I've had no luck with vsftpd in the past and this is my next attempt.

I want to use centos as a developer server on my desktop before deploying my stuff to the internet.
I have a netgear DG834G router. It's IP address on my local network is 192.168.0.1 and connected to the adsl line. The router is set up to act as an dhcp server too. On the router I have reserved ip address for the nics per their mac addresses.
My server is on a dual boot desktop. The other boot is XP and works fine, picks up dhcp.
I don't know how to connect Centos to the router.
I have tried to play with the network manager but to no avail.
I can ping localhost, interface eth0 is there, but i can't ping to the router.
I have set the manager system/administration/network to get dhcp automatically.
I can't activate the eth0 although the hardware device says it is OK.
I've looked at firewall and iptalbes.
