Error occurs with PartitionMagic 8.0
If you encounter Error 1516 with PartitionMagic 8, first run CHKDSK /F on the affected partition. For instructions on how to run CHKDSK, read How to Run Microsoft’s CHKDSK from the Command Line. If this does not fix the error, try running PartitionMagic with the /IFC switch, which causes file system errors to be ignored.

To run PartitionMagic with the /IFC switch

1. Boot from the first PartitionMagic rescue disk.
2. When you are prompted to insert the second rescue disk, press Ctrl+C to drop to the command (A:>) prompt.
3. Insert the second PartitionMagic rescue disk and type the following:

pqmagic /ifc
4. Press Enter.

yum install dkms dkms-fuse

Use the following…
rpm –import /usr/share/rhn/RPM-GPG-KEY-fedora
and
rpm –import /usr/share/rhn/RPM-GPG-KEY
That should fix your problem.

Installation

RedHat Enterprise Linux systems (as of versions 3 and 4) must install the YUM package. If installing via KickStart, install YUM as part of the %post install script. The following example shows installation from a private Network File System (NFS) mount on a secure build network. Read the rest of this entry »

Code Listing 5.2: Setting up iptables

First we flush our current rules
# iptables -F
# iptables -t nat -F

Setup default policies to handle unmatched traffic
# iptables -P INPUT ACCEPT
# iptables -P OUTPUT ACCEPT
# iptables -P FORWARD DROP

Copy and paste these examples …
# export LAN=eth0
# export WAN=eth1

Then we lock our services so they only work from the LAN
# iptables -I INPUT 1 -i ${LAN} -j ACCEPT
# iptables -I INPUT 1 -i lo -j ACCEPT
# iptables -A INPUT -p UDP –dport bootps -i ! ${LAN} -j REJECT
# iptables -A INPUT -p UDP –dport domain -i ! ${LAN} -j REJECT

(Optional) Allow access to our ssh server from the WAN
# iptables -A INPUT -p TCP –dport ssh -i ${WAN} -j ACCEPT

Drop TCP / UDP packets to privileged ports
# iptables -A INPUT -p TCP -i ! ${LAN} -d 0/0 –dport 0:1023 -j DROP
# iptables -A INPUT -p UDP -i ! ${LAN} -d 0/0 –dport 0:1023 -j DROP

Finally we add the rules for NAT
# iptables -I FORWARD -i ${LAN} -d 192.168.0.0/255.255.0.0 -j DROP
# iptables -A FORWARD -i ${LAN} -s 192.168.0.0/255.255.0.0 -j ACCEPT
# iptables -A FORWARD -i ${WAN} -d 192.168.0.0/255.255.0.0 -j ACCEPT
# iptables -t nat -A POSTROUTING -o ${WAN} -j MASQUERADE
Tell the kernel that ip forwarding is OK
# echo 1 > /proc/sys/net/ipv4/ip_forward
# for f in /proc/sys/net/ipv4/conf/*/rp_filter ; do echo 1 > $f ; done

This is so when we boot we don’t have to run the rules by hand
# /etc/init.d/iptables save
# rc-update add iptables default
# nano /etc/sysctl.conf
Add/Uncomment the following lines:
net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 1

If you have a dynamic internet address you probably want to enable this:
net.ipv4.ip_dynaddr = 1

Starting a VPN automatically on boot with Windows XP

I recently needed to figure out how to make a Windows XP machine connect to a particular VPN automatically on reboot, before anyone logged into the machine. I eventually managed to assemble bits and pieces of information floating around the net into a working solution to the problem, but it wasn’t completely addressed in any single location, so I thought I’d stick the details in my blog for other people to Google and use (if you found this blog entry useful, please add a comment and let me know!).

The first thing I tried was to look for a property I could set on the VPN network connection to tell Windows that I wanted this connection to start automatically when the machine boots. I couldn’t find one; I doubt there is one.

After that, I considered setting the “Set as Default Connection” checkbox for the connection, but I couldn’t find any documentation of exactly what that would do, and I was worried that another user of the machine might muck with that setting, perhaps with good reason.

All I could think of at this point was to write a batch file that would start the VPN and then tell Windows to run that batch file on reboot.

The key to the first part, starting a VPN from a batch file, is a Windows command-line tool called “rasdial”. If you run “rasdial connection-name username password” from the command line or a batch file, the specified connection will be started with the specified username and password. Dandy!

The key to the second part, getting Windows XP to run a batch file during reboot, is a utility called AutoExnt that Microsoft distributes for free but doesn’t include with Windows. The utility is described at http://support.microsoft.com/kb/243486/en-us, and although that article doesn’t mention Windows XP, it works just fine for XP as well. You can download it from http://download.microsoft.com/ by searching for “Windows Server 2003 Resource Kit Tools”, which may or may not still be available at http://www.microsoft.com/downloads/details.aspx?FamilyID=9d467a69-57ff-4ae7-96ee-b18c4790cffd when you read this blog entry. This should give you a file called rktools.exe, which when executed will install the tools on your hard disk, including the three files you need which are mentioned in the KB article referenced above.

With this knowledge in hand, here’s what you do to start a VPN when the machine boots:

1. Put “rasdial connection-name username password” in the file c:\windows\system32\autoexnt.bat which you create.
2. Copy the files autoexnt.exe, servmess.dll, and instexnt.exe from the resource kit tools folder you unpacked from the download mentioned above into c:\windows\system32.
3. Run “instexnt install”.

That’s it!
