Hi,
For our project we are using Solaris box.
After our build completion we keep kits to one directory and let users
to access it by FTP session.
So we create user account on Solaris and share this info. to
respective group of user.

I want to change this part and implement it like, 1.- Let user to
login to ftp server with its one of the property login as
'anonymous' ... but change is, user/password = 'anonymous/@client-
server'
2.- When user login as 'anonymous' run some script to check for its
password. Based on that update this to log file.

The main idea is to avoid creating new user on server and by just
validating password, can process which user has logged in.

So is it possible to run any script on server when any user logged in
through FTP server?

Thanks in advance.

I'm not sure what the diff is for you at all, but to each their own.

But what you want is not available in general. Specialized FTP daemons would.
Ie. ncftpd has a scriptable backend authentication system.

Some other Opensource ftpd's have different authentication systems
that are pluggable as well. Or you may even be satifisfied by their
virtual user systems, where they'll map all virtual logins to a single
unix login using different passwords (ie. ncftpd and proftpd support this).

It is also possible that you have a system which uses PAM; you can
create a specific PAM module which runs a script and which authenticates
the user without adding it somewhere

Thanks for reply and suggestion ...
I check with ncftpd it is fine for me .
