Hello all. Thank you for your responses. > PAM has no way (that I know of) of providing you with the IP address of > the user, though you can use pam_get_item to get the rhost or the tty. > > From the rhost or the tty, you can use whatever tools are available in > your language to get the IP address. Does pam-get-item with PAM-RHOST give me a hostname of a user? If so, I can call gethostbyname with the hostname. Whenever I tried pam-get-item(pamh, PAM-RHOST, (void *)&buffer) , buffer was unreadable. ntohl, htonl were not successfull. My DNS problem? Would you tell me how to use this function in detail? Thank you in advance.
