After upgrading two RH5.2 systems to glibc-2.0.7-29.2.i386.rpm, it became impossible to log on those systems using telnet or rlogin. rsh would not work either. Log entry after an attempt to telnet in: Sep 6 07:36:58 frank1 login[17517]: LOGIN ON ttyp4 BY fbures FROM frank Sep 6 07:36:58 frank1 PAM_pwdb[17517]: (login) session closed for user fbures The telnet session asks for login name and password, then exits. Login from the console works fine.
