How to perform Manual Telnet Test

We’ve already discussed about verifying a DNS capability. In such a way, this is for testing Telnet manually. You can follow the following procedure with a variety of the Operating Systems comprising Windows, UNIX and Linux. Using this step, you can know to perform a mail transaction manually through Telnet. If there is any difficulty to receive the replies given, you can copy the entire transaction and save it to report the error you received. If you want to make this test useful, you can run it directly from the Mail Server. Generally, the OK codes begin with the 2nn while the Error Codes begin with 5nn. If you’re connecting to AOL and receiving the 554 RTR:SC, a 5nn error code indicates a number of problems. For an example, if a syntax error or AOL systems blocks the incoming connections due to lack of RDNS or excessive user complaints, you can follow the following steps to perform a mail transaction through the Telnet manually.

1.    In the Command prompt, Type:
telnet 25
This command specifies to telnet to port 25 on an AOL mail host.

New Micro battery, power packed for high performance

For a size of a few millimetres, the new micro-batteries are powerful enough to jump start a car battery and then quickly charge the cell phone. Researchers from the University of Illinois have developed the micro batteries which can be used to drive compact electronic devices and new applications for radio communications. The micro batteries are so good that they can even out power the super capacitors. The results were published in ‘Nature Communications’ in the April 16 issue. The micro batteries have energy and power and with the researchers tweaking the structure of the micro batteries a little bit, its use can be for wide range applications. The high performance of the micro battery is based on its 3-dimensional micro-structure. Based on the design of fast charging cathode by Professor Paul Braun’s group, researchers developed the matching anode and integrated it with the fast charging cathode at a micro-scale and made a complete battery with high performance. These batteries cou
