<div>
<br /></div>
<div>
In my situation, my smartphone can not connect directly to my preferred primary wireless access point. So i need to setup a simple wireless repeater.</div>
<div>
<br /></div>
<div>
First is first, i need to connect to the primary wireless access point using my pc.<br />
<br />
After that, i configure my pc as a client to relay the internet to my secondary access point which is tp-link wireless access point and it already has its own DHCP server. I dont need to configure any DHCP server then.</div>
<div>
<br /></div>
<div>
My wireless adapter on my pc connected to the primary wireless access point is wlan1. This is how i do it.</div>
<div>
<br /></div>
<div>
internet --> wlan1 (on my pc) --> ethernet (on my pc too) --> network cable --> tp-link wireless access point --> smartphone</div>
<div>
<br /></div>
<div>
For your info, i already configured my tp-link wireless access point to match my ethernet configurations (IPs, Subnets, gateways).</div>
<div>
<br /></div>
<div>
All i need to do after connecting to primary wireless access point is run this commands.</div>
<div>
<br /></div>
<div>
<div>
ip link set up dev eth0</div>
<div>
ip addr add 192.168.137.1/24 dev eth0 </div>
<div>
sysctl net.ipv4.ip_forward=1</div>
<div>
iptables -t nat -A POSTROUTING -o wlan1 -j MASQUERADE</div>
<div>
iptables -A FORWARD -i eth0 -o wlan1 -j ACCEPT</div>
<div>
iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT</div>
</div>
<div>
<br /></div>
<div>
take note that my ethernet is eth0.</div>
<div>
<br /></div>

But it depends on your networking devices too. Using a gigabits ethernet adapter while using 10/100 Megabits of networking switches wont make your packet goes through faster (vise-versa)<br />
<br />
The theory to get faster internet is to have faster networking devices, from network adapter, cables or high speed wireless router and also a fiber internet.<br />
<br />
Load balancing is a technique to distribute packets to multiple gateways. Aim to optimize our available resources and the most important is to maximize throughput. Using multiple connections with load balancing instead of a single connections may increase reliability through redundancy.<br />
<br />
On Linux operating systems, route command has many options. One of them are nexthop option. The next hop, or gateway, is the address of the next station to which the packet is to be sent on the way to its final destination.<br />
<br />
If you are using both cable and wireless, operating system such as Linux or Windows will choose which one has the lowest latency to the gateway. In this case, cable will be always the winner.<br />
<br />
How to maximize your available resources ? The command is simple, when you are connected to both cable and wireless, just type ip route del default scope global ; ip route add default scope global nexthop via 192.168.0.1 dev eth0 weight 1 nexthop via 192.168.1.1 dev wlan0 weight 1 && ip r<br />
<br />
ip route del default scope global - to remove the default gateway that operating system has already choose for you based on the latency to the gateway.<br />
<br />
ip route add default scope global nexthop via 192.168.0.1 dev eth0 weight 1 nexthop via 192.168.1.1 dev wlan0 weight 1 - this command will define your gateways for your selected network adapters. You will need to readjust your gateway addresses depending on your networks configuration. In my case, my gateway for my cable connection is 192.168.0.1 and my gateway for my wireless connection is 192.168.1.1. Please notice that my wireless adapter name is wlan0.<br />
<br />
ip r - this command will show your gateways. You will see the outputs. For example,<br />
<br />
root@linux:~# ip r<br />
default<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>nexthop via 192.168.0.1 dev eth0 weight 1<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>nexthop via 192.168.1.1 dev wlan0 weight 1<br />
<br />
This script will do the magic job. When i connects to my wifi, it will automatically runs the load balancing script.<br />
<br />
#!/bin/bash<br />
<br />
IF=$1<br />
STATUS=$2<br />
<br />
if [ "$IF" == "wlan0" ]<br />
then<br />
case "$2" in<br />
up)<br />
ip route del default scope global ; ip route add default scope global nexthop via 192.168.0.1 dev eth0 weight 1 nexthop via 192.168.1.1 dev wlan0 weight 1<br />
;;<br />
<div>
<div>
esac</div>
<div>
fi</div>
</div>
<div>
<br /></div>
<div>
Put it on /etc/NetworkManager/dispatcher.d/ and name it as 90loadbalance.sh. This "90" in the name of the script means that this script will be executed in the last 10% of all scripts if you have a bunch of scripts to execute. Dont forget to make it executable. </div>
<div>
<br /></div>
<div>
Watch this video and see the output of iptraf for my 2 network adapter which is eth0 and wlan0.<br />
<br />

<div>
<br />
<br />
<br />
p/s - if you use desktop computer, you can install wifi usb adapter. You can try to install 3 or 5 network adapter (wifi, ethernet) to your desktop or laptop and readjust the command depending on your devices and gateways. Practically it will work, but i never tried. You also can make the script to run periodically, persistently by putting it to the crontab.<br />

Yup. So is the Citizen’s Band. The “ease” of using Windows robs you in the long run, though. It robs you of the basic right of a ham to experiment with your own equipment. It robs you by locking up programs in an operating system you have to pay for. And it robs you by being insecure on its most basic level.<br />
<br />
And it robs you because you pay for it in cash… over and over.<br />
<br />
Linux, on the other hand, fits right in with amateur radio. It was written by someone experimenting with electronics; as an amateur. Applications written for Linux are also usually written by people experimenting; and using their names on an open source copyright as evidence of competence to prospective employers.<br />
<br />
Maybe Linux isn’t as easy as Windows… but learning Morse Code or electronics wasn’t easy, either. Linux fits right in with ham radio. I should know… I’m 70 years old and was licensed when I was 14 and I’ve been using Linux since 1994.<br />

<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">FreeDV is a GUI application for Windows, Linux and MacOS (BSD and Android in development) that allows any SSB radio to be used for low bit rate digital voice.</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">Speech is compressed down to 1600 bit/s then modulated onto a 1.25 kHz wide 16QPSK signal which is sent to the Mic input of a SSB radio. On receive, the signal is received by the SSB radio, then demodulated and decoded by FreeDV. Communications should be readable down to 2 dB S/N, and long-distance contacts are reported using 1-2 watts power.</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">FreeDV was built by an international team of Radio Amateurs working together on coding, design, user interface and testing. FreeDV is open source software, released under the GNU Public License version 2.1. The FDMDV modem and Codec 2 Speech codec used in FreeDV are also open source.</span><br />

Why FreeDV?</h2>
<div>
<br /></div>
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">Amateur Radio is transitioning from analog to digital, much as it transitioned from AM to SSB in the 1950's and 1960's. How would you feel if one or two companies owned the patents for SSB, then forced you to use their technology, made it illegal to experiment with or even understand the technology, and insisted you stay locked to it for the next 100 years? That's exactly what </span><em style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">was</em><span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;"> happening with digital voice. But now, hams are in control of their technology again!</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">FreeDV is unique as it uses 100% Open Source Software, </span><em style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">including</em><span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;"> the audio codec. No secrets, nothing proprietary! FreeDV represents a path for 21st century Amateur Radio where Hams are free to experiment and innovate, rather than a future locked into a single manufacturers closed technology.</span><br />

Connecting Your Radio</h3>

<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">If you are lucky enough to have a "9600" input and output on your radio, this is the best connection for every digital mode, even 1200 packet, and your audio box should be configured for 9600 or "no pre-emphasis/de-emphasis" if it has that setting. If the radio's configuration menu has a 1200/9600 setting, leave it permanently on 9600.</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">The "9600" and "1200" settings are misnamed. "9600" should really be called "direct connection", and "1200" should be called "pre-emphasis". The pre-emphasis that comes with the 1200 setting doesn't help any digital mode. The 9600 connection is the most direct and unprocessed path to the modulator and demodulator of your radio.</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">Those who don't have a special connection for digital modes can use the normal audio inputs and outputs of your radio. The same cables and hardware that you use for other digital modes that are based on PC programs will work with FreeDV, but you will need a second sound interface for the microphone and speaker connections to the FreeDV program. A USB headset of the sort used by gamers is all you need for the second sound interface.</span><br />

<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">Turn off as much processing as possible. In general noise blankers, DSP band limit filtering and narrow bandpass filters are more likely to hurt than help, while compression, DSP noise or carrier elimination, and voice processing are </span><em style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">definitely</em><span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;"> wrong for Digital modes. FreeDV's HF modem does its own DSP, and in general this is true for other digital programs as well.</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">You can see the received effect of different settings in the S/N (signal to noise ratio) display of FreeDV. A higher S/N is better.</span><br />
<br style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;" />
<span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">Drive your transmitter and amplifier so that it emits 10% to 20% of its rated power continuously. There is a 12 dB peak-to-average power ratio in our HF modem, and peak clipping in your amplifier will reduce the received S/N. Modern transmitters and amplifiers are only as linear, and only have as much headroom, as is necessary for voice SSB, thus we suggest you maintain amplifier headroom by operating well below your full power output. FreeDV is more efficient than SSB voice, and will achieve similar range to an SSB signal driven at higher levels, and better audio quality. We encourage you to ask manufacturers and reviewers to start rating transmitter and amplifier linearity and headroom for </span><em style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;">digital</em><span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 12px; line-height: 17px; text-align: left;"> modes, not just SSB voice.</span><br />

from wikipedia,<br />
<br />
zRam is a module of the Linux kernel, previously called "compcache". zRam increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive. Since using RAM is faster than using disks, zRam allows Linux to make more use of RAM when swapping/paging is required, especially on older computers with less RAM installed.<br />
<br />
Even though the cost of RAM hardware is relatively low this feature still offers advantages for netbooks and other lower-powered laptops, virtualization and in the case of embedded devices, especially those that use flash memories that have a limited lifespan, dependent on write-use and thus wear out quickly when used as a swap device.<br />
<br />
Google is going to enable zRAM for Chrome OS by default.<br />
<br />
How to enable ZRAM for Debian or Ubuntu ?<br />
<br />
Starting with Ubuntu Precise, there is an official upstart script for Ubuntu by Adam Conrad to configure zram in the main repository, just simply type sudo apt-get install zram-config on terminal.<br />
<br />
For Debian, you need to download it manually and run it on boot.<br />
<br />
<br />
<ol>
<li>sudo wget https://raw.github.com/gionn/etc/master/init.d/zram -O /etc/init.d/zram</li>
<li>sudo chmod +x /etc/init.d/zram</li>
<li>sudo update-rc.d zram defaults</li>
<li>/etc/init.d/zram start</li>
</ol>
<div>
Check it status on dmsg and free -h </div>
<div>
<br /></div>
<div>
Hint: Using zram is also a good way to reduce disk read/write cycles due to swap on SSDs.</div>

<br />
Linux is new anymore, there are many custom Linux operating system that was designed for ham radio operators. Here are the list of famous Linux operating system for ham radio usage<br />
<br />
1. KB1OIQ - Andy's Ham Radio Linux DVD - This is a remastered version of Ubuntu Linux. As of version 13, there are 32-bit and 64-bit versions available.<br />
<br />
2. hamOS - A Debian based Live and Installable operating system for radio amateurs.
hamOS contains many preinstalled ham radio applications as well as a
custom menu. This respin is geared toward the newer linux user. hamOS
uses the lightweight LXDE desktop environment and is therefore suitable
for older hardware.
Check out the GetExtras folder on the desktop to run some custom
scripts that will automatically grab flash, codecs, and other non-libre
software.<br />
<br />
3. Ar-knoppix<br />
<br />
4. Harv's Hamshack Hack<br />
<br />
5. Digipup - based on puppylinux (lightweight linux distribution)<br />
<br />
6. Shackbox - Shackbox provide linux AND windows software like the famous ham radio
deluxe, trunking software and a lot of other software related to
electronics, antenna design and else.<br />
<br />
7. Hamux - CentOS based repository with ham radio software.<br />
<br />
However, you can choose any linux distro you like and install any ham radio applications that you desired. Since linux is opensource operating system, you can hack the source to suit your taste. Google, Yahoo also powered by linux operating system and small hardware such as switch, routers, acces point also powered by linux nowadays. Most of websites running on linux webservers. Happy Hamlinux-ing!<br />

1) Put on your USB drive, open terminal and type:<br />
<br />
sudo blkid<br />
<br />
It will list all your connected drives. Search for your USB stick you want to use as swap and copy the UUID (everything inside these quotes UUID="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX").<br />
<br />
This represents the individual name of your device.<br />
<br />
Also note the /dev/XXX point of your device.<br />
<br />
2) Now unmount your device by typing:<br />
<br />
sudo umount /dev/XXX (where XXX represents your device name)<br />
<br />
3) Format your USB stick as swap, e.g. by terminal<br />
<br />
sudo mkswap /dev/XXX (<-- be sure to use the correct device name here or you'll probably end up formatting the wrong drive!)<br />
<br />
You can also use Gparted if you want GUI<br />
<br />
4) Now you have to edit your /etc/fstab file, so type<br />
<br />
gksudo gedit /etc/fstab<br />
<br />
and enter the following<br />
<br />
UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX none swap sw,pri=5 0 0<br />
<br />
(for all the Xs, use the UUID number you got by typing sudo blkid)<br />
<br />
5) Now type<br />
<br />
sudo swapon -a<br />
<br />
For more info, man swapon<br />
<br />
<br />
p/s: you can define priority between your HDD swap and USB swap using the pri=value. The higher value indicates higher priority. You also can adjust the swappiness on /etc/sysctl.conf, the swappiness sysctl parameter represents the kernel's preference (or avoidance) of swap space. Swappiness can have a value between 0 and 100. Setting this parameter to a low value will reduce swapping from RAM, and is known to improve responsiveness on many systems.<br />
<br />
nano /etc/sysctl.conf<br />
<br />
add<br />
<br />
1. vm.swappiness=1<br />
2. vm.vfs_cache_pressure=50<br />

The cache will be stored in volatile memory. To use tmpfs for your chromium cache, please follow these steps<br />
<br />
<br />
1. add this to /etc/fstab, cache-chromium /home/your_user/.cache/chromium tmpfs defaults,noatime,mode=1777 0 0<br />
2. then rm -r /home/your_user/.cache/chromium (to delete everything you had cached)<br />
3. and mkdir /home/your_user/.cache/chromium (to create an empty directory).<br />
<br />
After reboot, the cache will be mounted in ram and you won't need to modify the launcher.<br />
<br />
Why dont use ramfs ?<br />
<br />
<br />
Primarily both ramfs and tmpfs does the same thing with few minor differences.<br />
<br />
Ramfs will grow dynamically. So, you need control the process that writes the data to make sure ramfs doesn’t go above the available RAM size in the system. Let us say you have 2GB of RAM on your system and created a 1 GB ramfs and mounted as /tmp/ram. When the total size of the /tmp/ram crosses 1GB, you can still write data to it. System will not stop you from writing data more than 1GB. However, when it goes above total RAM size of 2GB, the system may hang, as there is no place in the RAM to keep the data.<br />
<br />
Tmpfs will not grow dynamically. It would not allow you to write more than the size you’ve specified while mounting the tmpfs. So, you don’t need to worry about controlling the process that writes the data to make sure tmpfs doesn’t go above the specified limit. It may give errors similar to “No space left on device”.<br />
<br />
Tmpfs uses swap.<br />
<br />
Ramfs does not use swap.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5720339990533817277.post-57499512191791494752013-04-21T19:23:00.003+08:002013-04-21T19:23:43.884+08:00The Best Amateur Radio Logging App For Linux<div class="separator" style="clear: both; text-align: center;">

I am really satisfied with CQRLog for Linux. It support CW keying, general logging, DX cluster, eQSL, LOTW, hamQTH and QRZ.com search. It was developed by OK1CQR and OK1RR. It uses mysql as database server, cwdaemon for cw keying.<br />
<br />
CQRLog also support for digital operation, transceiver control and WinkeyUSB keyer. But, it lack of support for contest templates, rotator control and also cw repeat message. Hopefully that the developers will add this support.<br />

Provides radio control based on hamlib libraries (currently support of 140+ radio types and models), DX cluster connection, QRZ callbook (web version), a grayliner, internal QSL manager database support and a most accurate country resolution algorithm based on country tables developed by OK1RR. CQRLOG is intended for daily general logging of HF, CW & SSB contacts and strongly focused on easy operation and maintenance.</span>
<br />
<span style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px; text-align: justify;"><br /></span>
<br />
<div align="JUSTIFY" style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px; margin-bottom: 0.9em; margin-top: 0.5em;">
This is an obvious question if you plan to migrate your logbook to another program promising more comfortable operation and less paperwork. Every program has its own preferences and gets its own group of satisfied users who says <i>'this is the best one, nothing else compares to ***'</i> etc. CQRLOG is not different.</div>
<div style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px; margin-bottom: 0.9em; margin-top: 0.5em;">

Also, <b>CQRLOG is a must:</b></div>
<ul style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px;">
<li>if you are a dedicated DXer and/or Award hunter preferring 'classic modes' CW and SSB, active on daily regular basis who has a lot of contacts in his log</li>
<li>if you want a highest possible number of details on the station you are working or calling</li>
<li>if you want to have a very accurate DXCC, zones and IOTA statistics on the fly</li>
<li>if you want painless processing of a high number of QSL cards, LoTW and/or eQSL records</li>
<li>if you prefer the ergonomy over colourful screens with lots of buttons and boxes</li>
<li>if your operating style presumes to be focused more to your radio and the on-the-air scene than to your computer</li>
<li>if you prefer linux over Windows and want a more advanced logbook program, if you don't trust the commercial/shareware programs</li>
<li>if you are not satisfied with the support of your current logger</li>
</ul>
<br style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px;" /><div align="JUSTIFY" style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px; margin-bottom: 0.9em; margin-top: 0.5em;">
<b>CQRLOG would be probably an overkill:</b></div>
<ul style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px;">
<li>if you are a casual operator with quite few (thousands) contacts in your log</li>
<li>if you operate mostly on local repeaters or in local SSB roundtables</li>
<li>if DX is not the matter</li>
<li>if you prefer digital modes, however CQRLOG integrates with FLDIGI, a high-end digital mode interface (sound card based software)</li>
<li>if you are a portable (SOTA etc.) guru using a minimalistic computer (ie. palmtop etc.)</li>
<li>if you are QSL manager who needs a tool for offline processing of many logs</li>
<li>if you are operator of a club station, where every member needs his own log</li>
</ul>
<br style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px;" /><div align="JUSTIFY" style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px; margin-bottom: 0.9em; margin-top: 0.5em;">
<b>CQRLOG is not for you:</b></div>
<ul style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px;">
<li>if you want to use the same program for daily logging and contesting, however we don't exclude a CQRLOG clone dedicated to the contesters</li>
<li>if you operate a remote station which needs software control of almost everything, ie. you don't have any access to the front panel of your radio</li>
</ul>
<br style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px;" /><div align="JUSTIFY" style="color: #535353; font-family: sans-serif, Arial, Verdana, Helvetica; font-size: 13px; line-height: 16px; margin-bottom: 0.9em; margin-top: 0.5em;">
Anyway, CQRLOG is here and is for you. Try it out and if you decide to stay with this logger, we will be pleased. Of course, it will be very heartwarming if CQRLOG will became the reason to leave Windows and migrate to Linux.</div>

To fix youtube loading error on squid lusca, we need to modify the storeurl.pl file. Here is the fix by Syed Jahanzaib,<a href="http://aacable.wordpress.com/2012/01/30/youtube-caching-problem-an-error-occured-please-try-again-later-solved/"> http://aacable.wordpress.com/2012/01/30/youtube-caching-problem-an-error-occured-please-try-again-later-solved/</a><br />
<br />
Make sure to chmod +x, and chown the user and group of your squid. Mine is proxy, others maybe squid.<br />

To do that, you should roll up your sleeves and go to the hidden firefox settings.<br />
<br />
In address bar type:
about:config
You will see a textbox and a long list of options and settings.<br />
<br />
In the "filter" textbox type:
mousewheel.withnokey.sysnumlines
Change the default value to "false".<br />
<br />
Then type:
mousewheel.withnokey.numlines
The default value is "1". Increase this number to have faster scroll speed in firefox. I personally prefer "6".<br />
<br />
You don't even need to restart firefox to see the changes. They take effect on the fly.Unknownnoreply@blogger.com0
