Ubuntu8.10 slow Internet access !!

The real reason for slow Internet access is that it mainly takes time for firefox to resolve domain names.

Therefore, it is necessary to set DNS cache.

It is automatically set in windows, so you don't have to worry about it.

It will take some time in Ubuntu.

Therefore, you need to install a software called dnsmasq, which can provide dns resolution functions.

Of course, the dns cache function can also be improved.




Install dnsmasq

Command: sudo apt-get install dnsmasq

Edit the configuration file of dnsmasq

Command: sudo gedit/etc/dnsmasq. conf

Find the following item

# Resolv-file =

Replace with the following statement

Resolv-file =/etc/resolv. dnsmasq. conf

Make sure that you have not changed the/etc/resolv. conf file.

Then execute the command

Sudo cp/etc/resolv. conf/etc/resolv. dnsmasq. conf

Edit resolv. conf.

Command; sudo gedit/etc/resolv. conf

Remove all domain name servers and add the following lines


Save and exit

Run the following command:

Sudo gedit/etc/ppp/peers/wvdial

Add # before usepeerdns, that is, overwrite this statement.

In case, the resolv. conf setting is overwritten by pppoe.

Restart your computer. If you do not restart, you will find that the domain name cannot be resolved. Therefore, you must restart your computer to restart dnsmasq.

After restarting, you will find that firefox's resolution speed is N orders of magnitude faster than before.
