Maybe i should mention that i am executing this command from C# code.
Actually i am trying to send this command from C# FTP Client and please notice that it works flawless if i target only single file or directory. I just cannot make it to works for all files and dirs inside the selected directory. in a recursive manner.
For example this is the code that change permissions for index.html file:
Code:
TcpClient tcpClient = new TcpClient();
tcpClient.Connect(this.txtServerAddress.Text, Convert.ToInt32(this.txtPortNumber.Text));
NetworkStream netStream = tcpClient.GetStream();
System.IO.StreamReader strReader = new System.IO.StreamReader(netStream);
byte[] WriteBuffer = new byte[1024];
//passing ASCII characters
ASCIIEncoding enc = new System.Text.ASCIIEncoding();
// Pass the username to the server
WriteBuffer = enc.GetBytes("USER " + "username" + "\r\n");
netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
// Read the server response line from the stream reader
MessageBox.Show(strReader.ReadLine());
// Pass the password to the server
WriteBuffer = enc.GetBytes("PASS " + "password" + "\r\n");
netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
// Read the server response line from the stream reader
MessageBox.Show(strReader.ReadLine());
//CHANGE PERM. OF INDEX.HTML
WriteBuffer = enc.GetBytes("CHMOD 775 " + "public_html/index.html" + "\r\n");
netStream.Write(WriteBuffer, 0, WriteBuffer.Length);
// Read the server response line from the stream reader
MessageBox.Show(strReader.ReadLine());
tcpClient.Close();
As i said this code works like a charm changing permission of index.html

chmod
CHMOD(1) FSF CHMOD(1)NAME
chmod - change file access permissions
SYNOPSIS
chmod [OPTION]... MODE[,MODE]... FILE...
chmod [OPTION]... OCTAL-MODE FILE...
chmod [OPTION]... --reference=RFILE FILE...
DESCRIPTION
This manual page documents the GNU version of chmod. chmod changes the permissions of each given file according to mode, which can be
either a symbolic representation of changes to make, or an octal number representing the bit pattern for the new permissions.
The format of a symbolic mode is `[ugoa...][[+-=][rwxXstugo...]...][,...]'. Multiple symbolic operations can be given, separated by com-
mas.
A combination of the letters `ugoa' controls which users' access to the file will be changed: the user who owns it (u), other users in the
file's group (g), other users not in the file's group (o), or all users (a). If none of these are given, the effect is as if `a' were
given, but bits that are set in the umask are not affected.
The operator `+' causes the permissions selected to be added to the existing permissions of each file; `-' causes them to be removed; and
`=' causes them to be the only permissions that the file has.
The letters `rwxXstugo' select the new permissions for the affected users: read (r), write (w), execute (or access for directories) (x),
execute only if the file is a directory or already has execute permission for some user (X), set user or group ID on execution (s), sticky
(t), the permissions granted to the user who owns the file (u), the permissions granted to other users who are members of the file's group
(g), and the permissions granted to users that are in neither of the two preceding categories (o).
A numeric mode is from one to four octal digits (0-7), derived by adding up the bits with values 4, 2, and 1. Any omitted digits are
assumed to be leading zeros. The first digit selects the set user ID (4) and set group ID (2) and sticky (1) attributes. The second digit
selects permissions for the user who owns the file: read (4), write (2), and execute (1); the third selects permissions for other users in
the file's group, with the same values; and the fourth for other users not in the file's group, with the same values.
chmod never changes the permissions of symbolic links; the chmod system call cannot change their permissions. This is not a problem since
the permissions of symbolic links are never used. However, for each symbolic link listed on the command line, chmod changes the permis-
sions of the pointed-to file. In contrast, chmod ignores symbolic links encountered during recursive directory traversals.
STICKY FILES
On older Unix systems, the sticky bit caused executable files to be hoarded in swap space. This feature is not useful on modern VM sys-
tems, and the Linux kernel ignores the sticky bit on files. Other kernels may use the sticky bit on files for system-defined purposes. On
some systems, only the superuser can set the sticky bit on files.
STICKY DIRECTORIES
When the sticky bit is set on a directory, files in that directory may be unlinked or renamed only by root or their owner. Without the
sticky bit, anyone able to write to the directory can delete or rename files. The sticky bit is commonly found on directories, such as
/tmp, that are world-writable.
OPTIONS
Change the mode of each FILE to MODE.
-c, --changes
like verbose but report only when a change is made
-f, --silent, --quiet
suppress most error messages
-v, --verbose
output a diagnostic for every file processed
--reference=RFILE
use RFILE's mode instead of MODE values
-R, --recursive
change files and directories recursively
--help display this help and exit
--version
output version information and exit
Each MODE is one or more of the letters ugoa, one of the symbols +-= and one or more of the letters rwxXstugo.
