Connect your nokia phone with linux without pc suite!!

You can connect Nokia phones WITHOUT ANY CONNECTIVITY SOFTWARE OR SETUP. Amazing,?

I connected the mobile via the USB data cable and was just about to do what you instructed when a pop-up came saying: “Mobile Broadband Internet Modem” connected. Then it automatically showed a wondow with Bangladesh written on it and in the window there were options to select Aktel, Banglalink or Grameenphone.

I selected Grameenphone, it configured by itself and connected within 5 seconds. I really love Ubuntu. It keeps getting better and better.And just think, it automatically selects Bangladesh and gives option for GP, BL or Aktel.

So, people, order a Ubuntu 8.10 CD or download and burn it.Experience the magic.

speeding up internet connection in ubuntu

you can speed up internet connection by disabling IPV6(iff it is not needed)

sudo gedit /etc/modeprobe.d/aliases

edit the line alias net-pf-10 ipv6 as alias net-pf-10 off

then save & reboot

NB:- tested on ubuntu 9.04


wojox


Code:

gksudo gedit /etc/modprobe.d/blacklist.conf

and add the line:
Code:

blacklist ipv6

then reboot. This removes IPv6 from the kernel entirely, not just the browser

It does work. Without recompiling. If you "blacklist" the ipv6 module it will not be loaded ... which might on some systems indeed increase the performance of ipv4 a little bit.


Allen Kistler


What not loading ipv6 does is keep your machine from requesting IPv6 DNS records (AAAA) from your DNS server. Some DNS servers ignore requests for IPv6 addresses, which means the client has to time out the request before it asks for an IPv4 address (A). (If it retries, then it has to time out all the retries, which could be half a minute or so.) Most DNS servers are well-behaved enough now that they'll return an invalid request result or an unknown result if they don't support IPv6 requests, so the client can make an IPv4 request right away. In other words, for most people this tip isn't going to improve anything.

FWIW, Google did some initial testing a year or so ago that found a different, but related, problem. If the client is IPv6-enabled, but the Internet connection is IPv4-only, requesting *and*getting* an IPv6 address for a site makes the site completely inaccessible. That's why
they didn't assign an IPv6 address to www.google.com, but instead created a different name (ipv6.google.com) that probably points to the same pool of servers.

swap file vs swap partition

I have read here
(http://www.softpanorama.org/Internals/Filesystems/linux_swap_filesyst...
)

that swapping to a file is slower than swapping to a partition , based
on the following reasons

1) large files(swap file) will be somewhat fragmented forcing additional disk/head movement in some cases and that you will have to deal with metadata describing where on the disk the file blocks are. this eats up both in-system filesystem cache and causes additional disk activity while you load metadata that is not in cache is there any other reason that justifies this claim OR what exactly is the tradeoff between a swap partition and a swap file ??


september storm

This depends, are you using some type of faster raid setup, where the drives run in parallel? In 2.6 kernels, the swap is no longer slower/less efficient. If you have some type of raid for faster access, it could be better than a swap partition and a swap file is something you can recreate, move around, etc. more easily than adjusting a partition. Still, I prefer a swap partition over a file, just because I'm used to it. Most drives these days are not contiguous
anyway, so even a partition isn't what it used to be. Even still, I'll probably use a physical partition for swap for many years to come.



Doug Freyburber

My preference is based on error modes not on performance issues -

Using a swap file if it is not available until the file system
is mounted. If the file system is corrupted or lost the swap file
is not available. A swap file can get included in backups if you
are not careful about exclude lists. Also a swap file is
unavailable if the drive has a hardware problem or corrupt label.
If the file is deleted the inode stays active so the space stays
used but it goes away at the next reboot by which time you may
have forgotten about an accidental deletion. The swap file can
also be renamed making it unavailable at the next reboot.

Using a swap partition none of those issues apply. It's only
unavailable if the drive has hardware problems or if the label
is corrupted. The list of problems that make it unavailable is
much shorter.

swappiness parameter

linux 2.6 kernels added a new kernel parameter called swappiness to let the administrators tweak the way linux swaps. it is a no: from 0-100


in essence, higher values leads to more pages being swapped, and lower values leads to more applications being kept in memory, even if they are idle


the default value of swappiness is 60, you can alter it temporarily(until you next reboot) by typing as root:

echo 50 > /proc/sys/vm/swappiness


if you want to alter it permanently then you need to change the vm.swappiness parameter in the /etc/sysctl.conf file

FTP Program with Built-in Editor (Does it Exist?)

kestal

So I have been on Ubuntu for a while, and I think I may be overlooking something obvious, but I cannot be quite sure.


callan79

I'm not sure how much success you'd have editing multiple files on the fly, but I can tell you that editing one file at a time works fine.

Just install Filezilla or gFTP, configure 'gedit' as the editor, and you'll be right. When you save the file and close gedit, the FTP program will upload the new file to the server.

I do this all the time and it works well. Filezilla works better than gFTP in my experience.
