U盘操作系统Puppy Linux4.1正式版已于2008年10月6日发布了。初次体验Puppy4.1，你可能会觉得与4.0没什么区别，其实在底层（你看不到的基础部分）有了很大改进，大大提高了Puppy的硬件兼容性，并支持热插拔。官方发布的Puppy4.1 iso有两个：一个是基于Linux内核2.6.25.16的标准版本；另一个是基于Linux内核2.6.21.7的复古版本，仅适用于老硬件。

Tips and tricks

Upper and lower case

Linux always differentiates between upper and lower case. The two files MyFile.txt and myfile.txt are different file.

Special characters

Do not use special characters except for minus (-) and underline (_) for filenames or directory-names. Don't use the space-character. Use the characters A-Z, a-z, 0-9, -, _ only.

How to move files with ROX

If you left-click on a file and pull it to another directory the file is copied.

Make your own Puppy-CD

请查看puppy3.01使用手册中的制作自己的Puppy-CD

You can create your own Puppy-Linux with the following program.
Start the program "Menu | Setup | Remaster Puppy live-CD":

Click on the OK-button.

Choose the partition, on which a temporary working directory should be made with the tabulator-keys.

Encrypt with bcrypt

You should encrypt very sensitive files with the program bcrypt. Bcrypt uses the secure Blowfish-algorithm.
Open a shell and enter:
bcrypt /MyDirectory/MyFile
Then you are asked a passwort (at least eight characters long; you can abort bcrypt with "Ctrl" + "C"). Bcrypt encrypts your file and appends the extension bfe to the file. The original file is deleted automatically.
If you want to encrypt more than one file or a complete directory you should create an archive-file. Start the program "Menu | Utilities | Xarchive archiver".

Intrusion detection

For further improvement of your security you should store a checksum (a fingerprint) for all files. At regular intervals, but in any case before a backup, you examine the checksums of your files. If the checksums do not agree, the file was changed or deleted.

In order to compute and store the checksums, you open a shell and enter the following commands:

md5sum /usr/bin/md5sum

Create a checksum of the program md5sum.

Virus scanner
If you want to scan your files or a Windows computer you can use F-Prot virus scanner. You can download the program from the Forum. After you have downloaded and installed the program open a shell and enter the following command while you are still online.
/usr/local/bin/xfprot-gtk
or
/usr/local/xfprot/xfprot-gtk
Now you can update the virus definitions.

Firewall and daemons
You should always have an active firewall. It allows you to controlwhat ports your PC uses to communicate with the Internet. Ideally, allports are closed.
Start "Menu | Setup | Linux-Firewall Wizard".

Go to the "default" entry using the Arrow Down key (this option closes all ports) and press Return.

Now you can check the firewall rules.
