Projects / PFinger


PFinger is a highly configurable, secure and portable finger deamon. It is started by inetd but does not run as root. The service may be disabled for individual users by the administrator or by the users themselves. It offers configurable special files (e.g. a users PGP-Key could be retrieved with 'finger john.pgpkey@host), no printing of users home directory or shell and it also provides a graphical frontend that allows users to easily alter the output that will be sent, when they are fingerd.

            patch against v0.7.10
            I wrote a patch which fixes the following:
            buffer overflow for systems which do not have strdup, made a buffer a little smaller :-), changed buffersize for a filename to PATH_MAX handle-leak when loading fingerconf, extra logging when unable to open files, end string with 0x00 when strftime fails and/or when no getdomainname function exists extra logging when no memory is available for malloc/calloc, checking for NULL when allocating memory in some places handle-leaking when forwarding, ehr, something
            You can find the patch here:
