Hi,
We have an application which runs on telnet port, application structure is file based, we have to give write permissions to all the users to all files so that they can work on the system.
Recently we have noticed that all ordinary users can login through ftp and delete any file ( belonging to that application, because they have write permissions on all the files ), can anybody please let me know how can we block all user-ids logging into Solaris system through FTP except users whose user-ids start with "kcc"?
One more thing, we can't completely block port 21 because one FTP server is running on the server for the documentation, for example:
ftp://192.168.0.1/pub/English/Modules.html
We want to block FTP login through command line or any other FTP client, people can continue using FTP through web.
I hope, my query is explanatory enough.
