View Full Version : Add user without interacting.

Is there any function to change password without verification, when process is run by root.
Or any way to add user with password, without interacting.

I want to add user from web interface.

That's really true. Another interesting thing is that the confidence o say so easily. But doing is much more complicated.
Move 20 mins to your ref.. Did not find any turning point to solve the problem. I will be checking your resources with more time.

Here I'm going to explain more.

I wanted to make a web interface,
think signup.cgi is the file which has followgin permission:
-rwsr-sr-x 1 root nogroup 90908 Dec 15 22:58 signup.cgi

system("/usr/sbin/useradd -d /home/client/nilu -s /bin/mail-pass -p "Passwd9NEU" nilu");

I wanted to do this from that cgi file in C.

Giving error:
useradd: unable to lock password file

Can anyone help me to go ahead?

I solved the problem temporarily through a loop (each 5 second) process by root. This is much more secure. Though I don't think security is a problem even if that signup.cgi could do that. Ohh. I need encryption of passwords. char *crypt(const char *key, const char *salt); needs lots of library files.
