Mount filesyustem RW,
mount -no remount,rw /
Use vi to edit /scripts/system/clientpref/customization_application_startup.sh and add the lines. This should then look like:
#!/bin/sh
iptables -t mangle -D POSTROUTING -d 172.19.0.0/16 -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 900
exit 0;
Save the changes and exit vi
Write protect the startup script again:mount -no remount,ro /
I tried the solution below and it worked on my HP 450 G4 laptop,
Certain lines of Asus laptops emit an intermittent high-pitched noise resembling an electronic signal.
The lines affected include the following:
K5JR
K52JR
k42jr
K51AE
K51AC
K25F
eee PC 1201T
UL80J
This noise has been variously described as a whirling noise, a chirping noise, a whiney noise, and a screeching noise akin to fingernails on a chalkboard.
This noise can be very irritating and have been the subject of numerous complaints to the company. The company has not been very responsive to these complaints.
The good news is that there is a fix for this problem. The process takes less than five minutes. I’m no expert, but the following is what worked for me. Follow these directions at your own risk! If you have a better fix, please let them in the comments for everyone’s benefit.
Step 1.Click the Windows Start icon, and in the “Search Programs and Files” field type regedit
Step 2.
Navigate to the following folder:
HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Power \PowerSettings \54533251-82be-4824-96c1-47b60b740d00 \5d76a2ca-e8c0-402f-a133-2158492d58ad
Step 3.Click on ATTRIBUTES
Step 4.
On the top of the dialog box it should say DWORD
Step 5.Change the 1 to a 0
Step 6.Click on the Windows Start icon.
Go to Control Panel –>Hardware and Sound –>Change Plan Settings (for each plan that you use) –>POWER OPTIONS –>
Advance Power Settings –>Processor Power Management –>Processor Idle DisableSet both of them to Disable Idle
Since Lenovo FTP is having issues every now and then, I add here the script(s) to repair the VPD.
This script must be executed under linux enviroment, for Windows 10 you can also use WSL (Debian)
Note also that the user (default USERID) has to have S(upervisor) privileges and not O(Operator) under the MM config.
If the script seems to exit abnormally, the check to see if VPD values were corrected. If not, re-run script
before opening a support request.
If you come across a corrupted BIOS or a bad flash of an HP DV4/5/6/7, you may see the error System Board (00A)
Usually you can fix it with the HP DMI Tools from HP (HPBQ138.exe) , but in some cases the PCID is not 25 chars but 17. This come with the error below…
The input PCID is invalid
The tools here are the old versions which allows to edit the DMI to 17 chars
P.S. You will need a MS/Free/Mini-DOS bootable USB disk, and then copy the files
to the flash drive.

This is a small how-to for OpenWRTs running OpenVPN and connecting them by creating a site-to-site VPN tunnel.
-We assign 2 IPs, one for each tun0 interface on each router
-This guide assumes that you have already install openvpn packages on both devices
-In this guide A router has 192.168.10.x network and 192.168.251.1 IP in tun0 interface, and router B has 192.168.22.x network with 192.168.251.2 IP in tun0 interface.
-You will need the file /etc/openvpn/static.key or generate a new one in one router and copy it to the other.
-Port 1195-1194 can be changed
-You can have multiple blocks of configuration in OpenVPN, one for Road Warriors (see here) and the one documented here.
-Follow the guide here for installing Open VPN and configuring the interfaces tun0/tun1 etc
Router A
config 'openvpn' 'site-to-site'
option 'enable' '1'
option 'port' '1195'
option 'proto' 'udp'
option 'dev' 'tun'
option 'secret' '/etc/openvpn/static.key'
option 'ifconfig' '192.168.251.1 192.168.251.2' #this device tun0 / remote device tun0
option 'keepalive' '10 120'
option 'comp_lzo' '1'
option 'verb' '10'
option 'float' '1'
option 'local' '192.168.10.1 1195'
option 'remote' 'remote.host.name 1194'
Add to /etc/firewall.user
iptables -t nat -A prerouting_wan -p udp --dport 1195 -j ACCEPT
iptables -A input_wan -p udp --dport 1195 -j ACCEPT
iptables -I INPUT -i tun+ -j ACCEPT
iptables -I FORWARD -i tun+ -j ACCEPT
iptables -I OUTPUT -o tun+ -j ACCEPT
iptables -I FORWARD -o tun+ -j ACCEPT
Add a static route between the 2 LANs
route add -net netmask 255.255.255.0 gw 192.168.251.2
Router B
config 'openvpn' 'Site-to-site2'
option 'enabled' '1'
option 'dev' 'tun'
option 'ifconfig' '192.168.251.2 192.168.251.1'#this device tun0 / remote device tun0
option 'secret' '/etc/openvpn/remote.key'
option 'keepalive' '10 120'
option 'comp_lzo' '1'
option 'persist_key' '1'
option 'persist_tun' '1'
option 'verb' '3'
Add to /etc/firewall.user
iptables -t nat -A prerouting_wan -p udp --dport 1194 -j ACCEPT
iptables -A input_wan -p udp --dport 1194 -j ACCEPT
iptables -I INPUT -i tun+ -j ACCEPT
iptables -I FORWARD -i tun+ -j ACCEPT
iptables -I OUTPUT -o tun+ -j ACCEPT
iptables -I FORWARD -o tun+ -j ACCEPT
Add a static route between the 2 LANs
route add -net netmask 255.255.255.0 gw 192.168.251.1
