How To Disable Telnet For Linux User

If you need to disable the telnet function for a particular UNIX/Linux user, it can be done by editing the /etc/passwd file and replace the shell (say /bin/bash) for that user’s entry with something else (say say /dev/null).

If it doesn’t work, then do these:-

- Login as the user.
- Edit the .profile (with vi editor) and add in the last line “exit”.
- Save the .profile.

With that, if the user tries to do a telnet, he will be automatically kicked out.

Mobile messaging for Lotus Domino

Now, the Lotus Notes user can look forward to have the push mail service using a mobile device if the following criteria are met:-

- Lotus Domino 8.0.1 server or later (Lotus Domino 8.5 will be required for Nokia S60 support).
- Mobile device running under Windows Mobile (WM) 5.0, 6.0 and 6.1 releases. Or, Nokia mobile device running under S60 (Symbian OS platform).

To support push mail access on the mobile device, you just simply need to install the IBM Lotus Notes Traveler software onto the device. After that, with some simple configuration on the device itself, it will be able to do the real-time replication (automatic) of Lotus e-mail (including attachments), calendar, address book, journal and To-Do-Lists.

With this major development of IBM's efforts, IBM has expanded the mobile support for the Lotus software portfolio (at no additional cost). In other words, the Lotus Notes user no longer needs to reply on Blackberry to pull email from Domino server, which requires additional infrastructure, overhead and cost.

To have a better picture about Lotus Notes Traveler on mobile, you may refer to the video clip below:-

Hibernate feature in Windows XP

<-- Yuiyuan (豫园 in Shanghai)

Do you get frustrated while you wait around for the slow WinXP computer to startup? To speed up the process, you should considering using hibernate.

When you put the computer to hibernate when powering off the system, the hibernate feature saves everything in memory on disk and then turns off your computer. When you restart your computer the next time, your desktop is restored exactly as you last left it. In other words, you can save some times in reopening the programs again when startup the computer.

To enable the Hibernate feature, go to Control Panel, double-click Power Options, and then click the Hibernate tab. Click to select the Enable Hibernate check box.

To put the computer to hibernate when shutting down, you just need to press ALT + CTRL + DEL key and it will give you the option to hibernate.

Parental Controls

If you are concerned about what your children are surfing on the internet or want to restrict them on the time spent in browsing, you may use the built-in Parental Controls to do the restriction… if your computer is running on Windows Vista.

Windows Vista comes with Parental Controls (not for Windows XP). Even though it is not very powerful, it still serves the purpose.

Assuming you already have a user account created for the child, follow the steps below to block their usage:-

1. Start > Control Panel > User Accounts and Family Safety.
2. Click “Set up parental controls for any user” and select the user account that you want to control the access.
3. Click “Time limits” and then click on the blue box next to “Blocked”.
4. Use the grid to set blocks of time when your child can use the computer.

With this setup, your child will not be able to log on during blocked times. If the child has already logged on when time limits expire, he/she will be automatically logged off by the system.

For details, you may refer to:-

As a parent, if you willing to spend money, then you can consider getting “Advanced Parental Control” for a better control (can also monitor the usage of your PC).

RepliGo - Viewing Blackberry’s attachment

In my previous post in last year September, I highlighted about the BeamView software (by Beamberry company) where it can use for attachment viewing on blackberry device... in a way that the document on the blackberry can be displayed in their original form as they would look on the computer.

In actual fact, there is another more established software called RepliGo (by Cerience Corporation) that can do the same task. I didn’t mention it because BeamView still offers for free during that time.

With RepliGo, users also have the ability to send original documents as attachments in an email, print to HP Bluetooth printers (beautiful, right?), store documents locally and on the server, and even fax original documents right from the BlackBerry.

For organizations having BlackBerry Enterprise Server, I would think that deploying RepliGo is the only best choice for attachment viewing (compare with Beamview) if they are concerned about security (without compromising content).

This is because Cerience has a cooperate solution called “RepliGo Server” where it can be installed on your own Windows server in your premise (either a separate Windows machine or directly onto the BlackBerry Enterprise Server machine). To understand how the communication flows between the server and device, you may refer to the diagram above.

As for Beamview solution, they don’t have a cooperate edition. All the documents are processed and stored on the provider’s BeamBerry servers.

I also notice that RepliGo is an Alliance member of Blackberry. So, I guess you can have another choice now.

How to save Flash (SWF) file from web page onto your PC

Someone ever asked me a question on how to download the animation or cartoon game was created using Flash from the Web page onto his own hard drive.

The answer is that... it can be done regardless whether you are using Internet Explorer or Firefox as a browser even though the technique is not straight forward (because there is no option to save the flash file when you right-clicking the item).

Here is the method to save flash in IE browser...
- At IE, click Tools - Internet Options
- In the General Tab, click the "Settings" button available in the Temporary Internet Files group.
- Click "View Files" to open your Temporary Internet Files folder.
- Once you find the right flash file, right-click & choose Copy. Then paste the swf file in any other directory... Now, you are done.
- After that, you may go to that directory to do off-line viewing.

Increase font size in Lotus Notes

It is not surprised that Lotus Notes user doesn’t know where to change its font size for viewing because the setting is not done at the GUI interface.

For Lotus Notes 5 (or later) client, you can customize the display size of the default fonts by adding the following setting to your NOTES.INI file (inside the Lotus Notes directory):-

Display_font_adjustment=x

Where x is the number of points added to the default size, and is a number between 0 and 25. For example, if you need to increase the font size to 5, you would type:
Display_font_adjustment=5

Virtual PC and Virtual Server

The following article describes the differences between Virtual PC & Virtual Server:- http://www.microsoft.com/windowsserversystem/virtualserver/techinfo/vsvsvpc.mspx

In summary…

1. Virtual PC is a virtual machine software for running on desktop operating system whereas Virtual Server is a virtual machine software for running on server operating system.

2. Virtual PC is NOT free, but Virtual Server is free.

3. For Virtual PC, both the host operating system (the one on which you install Virtual PC) and the guest operating systems (the ones running inside virtual machines) must be desktop operating systems. For Virtual Server, supported host and guest operating systems are all server operating systems, except for Windows XP Professional, which is supported as a host operating system.

How can your use Virtual PC/Virtual Server?
There are a number of other ways you might want to use Virtual PC. For example, you may use Virtual PC at home so that your family can use it to surf the Internet. This can then eliminate worries about applications or files your family might download—those downloaded materials will not affect the host operating system. If the virtual machine becomes corrupted or infected with a virus, you can simply delete the virtual machine and start it over.

Proofpoint -- Anti-SPAM

I have just tested an anti-SPAM product called Proofpoint for the E-mail system lately for a couple of months. Before that, I have tried the Symantec, Trend Micro & Barracuda and it is the best among these few. Till now, there is not a single false-positive detected for mails. According to my research, it is the third generation product which uses MLX technology for mail scanning. It is really GOOD!
