View 1 Replies View RelatedI had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.
I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).
These are the commands I used:
Quote:
p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*
[Code]....
I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...
So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.
It's still trying to use /dev/disk/by-uuid/412d... to boot.
What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

I am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?

View 2 Replies View RelatedOur hardware that is running DNS is very old (Pentium 1 Redhat release 6.2), and I want to migrate the DNS Records to a new computer (Pentium 4 Debian Lenny). There is no GUI environment on the old server: no Gnome or KDE. I may consider using VMware Workstation for this project.
1. I don't have very much DNS experience. Is this a painless process?
2. Are there commands that I can run to export the DNS records from the old server?
3. Are there commands that I can run to import the DNS records to the new server?
4. What other advice do you have that could help this process?
I need to migrate data from Lotus Notes (LN) to MySQL system. I googled around, but didn't find much information about it. The LN has an option to export data like Lotus 1-2-3, which allows you to open the data into excell, but nothing apparently to MySQL. I also opened the MySQLMigration-ToolKit. In the import DataBase System, it doesn't appear LN as an option of supported systems. We are trying to keep things using freeware and cross-platform, although sometimes providing final customer products that run on MS. There is any tool available around, or should we go and code the routines to read the tables from Lotus to MySQL using a programming language like C?

View 1 Replies View RelatedI am looking for ideas for getting windows users into an ldap server. I am currently running a Linux server for my department and need to create an LDAP server which mirrors the username/password information for all of us as they are stored in the windows server here. I have the openldap server up and running on Ubuntu 8.04 and it works great; I now need to find some way to import user info into this from windows. I've seen discussions of using ldifde.exe to export the AD users into an ldif file. Is this the simplest way to go about it?
Our Linux server is currently providing us with much needed services using apache, and apache is authenticating using LDAP to our windows server (Using our windows username / password is required functionality). This windows server has some problem which causes it to delay for inordinate amounts of time between authentication requests and responses. The situation is such that this problem will not be addressed by IT staff. However, I have control over the Linux server so I am looking to just mirror the windows server on an LDAP server of my own. I could get away with updating the passwords in the Linux server.
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).
We have two CentOS 5 servers in production (web and database). We are setting up a single staging server that will mirror the configurations of these servers as closely as possible. What is the easiest way to ensure the exact same software and configs as the production servers are setup on the new staging server. Our contracted data center provider has already informed us that they do not perform images and NO we do not have physical access to the machines. It is undetermined whether we will be virtualizing the staging server into two virtual servers yet, so for the purposes of this post lets assume we are not. I'm seeking a faster/more precise method than doing this by eye and hand.
Some information on our web server code...
I've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so

View 4 Replies View RelatedWe currently have a SUSE Apache2 reverse proxy server setup to reverse proxy (proxy_mod) our GroupWise Web Access server. Our SUSE box is located at www.domain.com. Our GroupWise Web Access server is located internally and is called GWMail.

We would like to set up reverse proxy to be able to reverse proxy to the Exchange Server from the outside world. Unfortunately the snag we are running into is that Exchange needs to run on port 443, and forwarding to port 443 has been a little tricky. I've read elsewhere we need to implement a generic TCP proxy, such as IPtables. what we need to do to get our SUSU Apache2 server to be able to reverse proxy to our Exchange server on port 443.
