- Steps to DR restore Windows 2000 Server with build-in tools
- Backup with NT backup, ERUNT
- Install Windows 2000 Server with Storage drivers
- Boot into Windows PE / another IDE harddisk with drivers
- Restore from BKF (run ntbackup.exe from the C:)
- * Copy backup data into DVD or copy to a local harddisk, Windows 2000 may not able to detect USB drive in safe mode
- Restore registry from ERUNT (if has AD, system will unable to normal bootup yet)
- Re-config the Network Card's IP address if the NIC is changed
- Boot into Windows 2000 Server in Safe Mode/Directory Restore Mode, restore the System State from BKF
- Check Event log for any missing
- Create a Super Floppy USB Key
Boot into Linux, and format the USB key with: mkdosfs -I /dev/sda
- Windows Server 2003 ASR backup without a floppy drive
Solution: Perform an ASR backup on the computer without the floppy drive. Copy the asr.sif and asrpnp.sif files located in the %systemroot%\repair directory to another computer with a floppy drive, then copy those files onto a floppy disk.
For Windows 2000, ASR will stop if no floppy present
- Auto ESR backup at Windows 2000 without a floppy

5% discharge rate per month
keep it cool
at 0 degree C, 40% charge, 2% capacity lost per year (keep at refrigerator)
at 25 degree C, 40% charge, 4% capacity lost per year
at 25 degree C, 100% charge, 20% capacity lost per year
at 40 degree C, 100% charge, 35% capacity lost per year
Troubleshooting
- JavaScript error in IE, could not see YouTube movie
- 1. Close all IE windows, uninstall Flash Player, then reboot, and reinstall
- 2. Try to disable most strange plugins like: ICQ, MSN Toolbar, Google Toolbar, Yahoo Toolbar, Skype
- 3. Use Mozilla Firefox

- Official Adaptec AIC7xxx driver for Linux
- Memory Technology Device (MTD) Subsystem for Linux
- Only the 2003-09-01 snapshot works ok with DOC2000 on kernel 2.4.22. 2003-10-01 to 10-09 could not compile!
- Embedding Redhat Linux in a DiskOnChip - HOWTO (PDF)
1. format DOC with TrueFFS tool from M-System? Version 4.2 firmware only!
2. Create /dev/nftla* device files
3. mount the flash device root to /flash
(as well as /boot and /etc, if they're seperated)
4. run "rdev /flash/boot/bzImage /dev/nftla2" to direct modify the kernel
to start root from /dev/nftla2, lilo-mtd cannot help
5. Use modified lilo from the MTD utils to run lilo for DOC
(e.g. mount the flash at /flash, /etc/lilo.conf at the flash's root)
/etc/lilo.conf must contains:
boot = /dev/nftla
disk=/dev/nftla bios=0x80
run:
./lilo-mtd -r /flash -C /etc/lilo.conf
- Another information on using DOC2k w/Linux
- Either use MTD or M-System, MTD seems easier
- Recent MTD seems only work with DOC firmware version 4.2
- Example on using M-System DOC with Kernel 2.4.17 MTD
Enable kernel options:
MTD Support, Debugging, FTL, NTFL, NTFL write support,
M-Sys DOC 2000/Millenium.

- Generic TCP Proxy on Linux
- Squid HTTP Proxy
- Transparent Proxy to a remote box
Setup squid proxy:
http_port 8080
httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on
Run at iptables box:
iptables -t nat -A PREROUTING -i eth0 -s ! squid-box -p tcp --dport 80 -j DNAT --to squid-box:3128
iptables -t nat -A POSTROUTING -o eth0 -s local-network -d squid-box -j SNAT --to iptables-box
iptables -A FORWARD -s local-network -d squid-box -i eth0 -o eth0 -p tcp --dport 3128 -j ACCEPT
- Problem on HTTPS transparent proxy
HTTPS traffics are encrypted, we can at most log the connection as "CONNECT" in squid if IE set the proxy server.
