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.

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
