Start installing the open terminal emulator, continue to perform the following command to install the GAIM version 0.58, namely: CD / TEMP (enter the temp directory) RPM -IVH GAIM-0.58-2.i386.rpm (installation software) When the installation is successful, you can Establish a GAIM icon on the GNOME or KDE desktop. Continue to install QQ plug-in, type command: gunzip libqq-0.0.3-ft-0.58-gcc296.so.gz (decompress file) CP libqq-0.0.3-ft-0.58-gcc296.so / usr / lib / gaim (Copy plug-in to the GAIM library directory) The Software Settings When the GAIM version 0.85 is first launched, the login interface will appear. First select "Plug-in", click "Load" in the Plugin dialog box, load libmsn.so and libqq-0.0.3-ft-0.58-gcc296.so file, and turn it off after confirmation. Then select "All Accounts", continue to click "Add" in the account editor that appears, when you appear, we can enter your QQ or MSN number, login name fill in the QQ number or MSN mailbox. The password fills in the corresponding QQ or MSN password, Alias fill in its own nickname, the protocol selects the corresponding QQ or MSN, and other settings can be default. You can log in when all settings are complete.

At present, there are a few ADSL equipment on the market, and their way to work has some subtle differences.
It is the process of completing the Internet through virtual dialing, that is, using the PPPoE device to perform virtual dial-up calls, it is an automatic dial-up work after power-on, then left to our interface is RJ45. The gateway that is generally left to our Dalian area is 10.0.0.2. This device is most likely to deal with. Finally, it is directly assigned to a fixed IP, which is relatively easy to deal with it. 1. The first need is dialing: Several devices communicate with the computer via the ETH interface, so the connection of the hardware device is first, especially the broadband cat, must confirm the correctness (otherwise, don't go anything in a while, don't just count, you don't think about me) and start the system, Confirm that the software is installed on the system (to find the user via rpm -qa | grep pppoe), if the user is not installed, in the disc or go online to Down, after installing, perform ADSL with root users Setup, this enters the setting status of ADSL data, requires input to apply for broadband usernames and other information, confirm that there is no problem, accept until the end (inside is E text, but can understand, simple, I usually don't have to use a firewall setting, I can choose 0, everyone can consider). After the configuration is complete, the ADSL-START is executed with root users, which will make ADSL's dial-up work, will be online, if there is any specific problem, look at the log (/ var / log / messages) tells you what.
Stop ADSL, execute ADSL-STOP (very simple) 2. The other two are easier to deal with: full-to-day cat: Just set your network card to an IP of a 10 network segment, then the gateway refers to the whole gateway To the IP of the cat, on (10.0.0.2), basically no too much problem fixed IP: Like the NIC configuration, the IP, gateway, and DNS can be fixed by the application. 0014 Let Linux automatic synchronization time (shunz) VI / etc / crontab plus a sentence: 00 0 1 * * root rdate -s time.nist.gov 0015 Linux online resources What are the online resources?
