I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
I would like to ask the expertise here about this issue which I am having at the moment. I am unable to VNC to my server. I have configured all the necessary steps to enable the vncserver. But there will be an error stating "main: unable to connect to host: No route to host (113". I have checked on my network side which I did not block any what so ever port on the firewalls and the switches. I am able to ping the server but the main problem is that I am unable to remote VNC to that server. I have several servers which I have configured with the same configuration and only that particular 1 server that could not VNC. This is getting frustrating.

View 7 Replies View RelatedI recently did a clean install of Fedora 11 (from Fedora 10). In Fedora 9 and 10 I used a remote font server so that I could launch HP OpenView over a VPN tunnel. The procedure would go something like this:
*connect to VPN
*xset +fp tcp/<hp_ux_server>:7000
*ssh -X user@hp_ux_server
*launch OpenView
OpenView requires the fonts that are installed on the HP-UX server, hence the need for the xset command. Now since the installation of Fedora 11, I cannot get the xset command to work.
xset fp+ tcp/<hp_ux_server>:7000
xset: bad font path element (#23), possible causes are:
Directory does not exist or has wrong permissions
Directory missing fonts.dir
Incorrect font server address or syntax
I have turned off the firewall to make sure it wasn't blocking the request. But to no avail. I have also had two other people with Fedora 11 machines try this, they get the same error. Were there major changes in the X server from Fedora 10 to 11+?

I have a small home-office network. On that network I have two linux computers, one is a client the other a server.
On the server I have NFS Server setup and mount some NFS exports on the client computer.
On the server I have the firewall on and here it becomes a little tricky.
Since both the server and the client connect to the router the interface (eth1) is theoretically both an internal & external zone.
The router is commercial grade and therefore has a good firewall on it which is also setup. Therefore the firewall on the server is really more of a backup than a necessity. But that's fine, and by having the server's firewall on 'fail2ban' is able to work which I like to have working so I don't want to just turn off the server firewall even though I have good security from the router.
However, when I turn on the server's firewall, the client computer cannot see the NFS server when scanning for server -- done by: clicking on "Choose" next to "NFS Server Hostname" when adding an NFS share in the NFS Client in YaST. Clearly something is being blocked even though I have both "NFS Client" and "NFS Server Service" allowed in the server firewall. The Firewall config. files for these are below.
The Firewall configuration is pretty much "out of the box". That is I have the services I need opened up for the external zone, the other zones are left at their default which means the internal zone, although not used (i.e.: attached to any interface), is completely open.
The perfect solution I guess would be to setup my client computer to connect through a different NIC (perhaps eth0), make that the "Internal Zone" and therefore allow all traffic through to it while still blocking the server from the external zone. However, I cannot make that physical change to my network for now so I am looking for an in between (non-perfect) solution.
In this case I am guessing that means opening up extra NFS ports to the external zone so I have full NFS functionality. I don't mind this because like I said, the router firewall is the main line of defense anyway.
So, given all of the above could someone tell me what I would need to additionally open up in the server firewall to make the NFS server detection work on the client while the firewall was on. Or, if you have a cleverer/better solution without me changing my physical network that would be great.
Hopefully I have written this in enough detail and clearly enough so that all the parameters are clear but if not, feel free to ask me what you like and I'll try to make it clear.

View 4 Replies View RelatedMy desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003.

The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.
I am not seeing what i am doing wrong here, but here goes:
From my server I need to run a command for backup on 25 remote servers (through a script). Now I have pushed the public keys for remote ssh connectivity on all of them and it works ( I can push files using rsync without the need to enter passwords on the remote servers), howver, I need to run the following command:
ssh odsadmin@10.139.111.1 'cp -a /var/www/life /var/www/life-v4'
when I run this command, I keep getting asked to enter the password, I even tried putting sudo in front of the cp, but still get the request to enter the password.
I wanted to set up a secure FTP server with proftpd so I can put some large files on the web for my pops. Here is my problem, I use a clearwire modem that won't allow you to change any of the settings but appears to have some pre-set firewalling capabilities. I also have a linksys wireless router connected to the modem. That firewall has all the port forwarding settings ready to go, and there hasn't been an issue with anything else, so here it goes.
I have a properly configured secure FTP setup with proftpd and the client app I'm using is Filezilla. I know it is configured right because I was able to use the FTP server via my LAN. Maybe my logic is wrong but, I was connecting to the FTP server at it's IP on the LAN of 192.168.1.5:21. If I wanted my pops to connect from out of state I would give him the ip the internet sees when I surf the web, right? Looks something like this 68.44.22.113. I should tell him to configure Filezilla to connect to 68.44.22.113:21. If my logic is wrong, please let me know, because when I try to do this I get an error that says connection refused by host.
