Useful Windows DOS Commands For Linux Users

Useful Windows DOS Commands For Linux Users
the most useful DOS commands available in Windows XP. DOS Commands must be run at the prompt of the Cmd.exe. To open Command Prompt, click Start, click Run, type cmd, and then click OK.
Now try some useful commands;
1. To convert FAt32 volume into NTFS volume
use :- CONVERT F: /FS:NTFS
converts F drive into NTFS format.
2. Disconnect all the connection using net use
use : - net use * /del /yes
This will delete all the connection to your windows system; means If you have already connected to some system with shared folders and provided log in and password. After using this command you need to type login and password again. One can disconnect specific connection using net use.
: net use will display all the connection list.

3. Today I learn about SDelete command. (works on Windows NT/2000's (Win2K) )
SDelete is a command line utility that takes a number of options. In any given use, it allows you to delete one or more files and/or directories, or to cleanse the free space on a logical disk. SDelete accepts wild card characters as part of the directory or file specifier.
usage is to securely delete existing files (replacement of delete). or in other words Delete Files Permanently from your Computer.
why use sdelete?
When you delete files or folders, the data is not initially removed from the hard disk. Instead, the space on the disk that was occupied by the deleted data is "deallocated." After it is deallocated, the space is available for use when new data is written to the disk. Until the space is overwritten, it is possible to recover the deleted data by using a low-level disk editor or data-recovery software.
To view help at the command-line, at the command prompt, type the following:
CommandName /?

Linux SMB write performance With Simple Tips

SMB write performance can be increased by Tuning the buffer cache. The secret to good performance is to keep as much of the data in memory for as long as is possible. Writing to the disk is the slowest part of any filesystem. If you know that the filesystem will be heavily used, then you can tune this process for Linux Samba. writing out dirty blocks to the disk until the filesystem buffer cache is 80 percent full (80). default is 40%, source = http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap29sec287.html by writing echo 80 > /proc/sys/vm/dirty_ratio I am getting around 2MB increase while write operation, tested in Xp. I have tried with this single option, as the ref source is for linux 2.2 and we are using 2.6 kernel. we can try out Linux General Optimization suggested at http://tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/gen-optim.html Tried with smb.conf, I am getting around 1MB gain while read and write. socket options = TCP_NODELAY I...
