to block the files uploading via the port

Hi Folks,

I am not good in shell scripting. Please help me with my problem. Is it possible to block the file named "ss.cgi" using the port 25 to upload.
# 2  
create the file with read only permission, then no one else can override it?

Hi,

I am sorry, Let me be more clear on my issue. Some hackers are injecting the file ss.cgi through the port 25 with different ips. So, what I need is, if any ips establishing the connection with the port 25 for the file ss.cgi should be denied. I am root user. Is there any script can be implemented for this or else is there any root level restrictions can be done for this.

Regards
Siva
