Use this ++program for automatic reverse finger probes from the ++.B tcp_wrapper ++.B (tcpd) ++, not the raw finger command. The ++.B safe_finger ++command makes sure that the finger client is not run with root ++privileges. It also runs the finger client with a defined PATH ++environment. ++.B safe_finger ++will also protect you from problems caused by the output of some ++finger servers. The problem: some programs may react to stuff in ++the first column. Other programs may get upset by thrash anywhere ++on a line. File systems may fill up as the finger server keeps ++sending data. Text editors may bomb out on extremely long lines. ++The finger server may take forever because it is somehow wedged. ++.B safe_finger ++takes care of all this badness. ++.SH SEE ALSO ++.BR hosts_access (5), ++.BR hosts_options (5), ++.BR tcpd (8) ++.SH AUTHOR ++Wietse Venema, Eindhoven University of Technology, The Netherlands. ++ +diff -Naur tcp_wrappers_7.6/safe_finger.c tcp_wrappers_7.6.gimli/safe_finger.c +--- tcp_wrappers_7.6/safe_finger.c 1994-12-28 10:42:42.000000000 -0600 ++++ tcp_wrappers_7.6.gimli/safe_finger.c 2002-01-07 08:50:19.000000000 -0600 +@@ -26,21 +26,24 @@ + #include + #include + #include ++#include + + extern void exit(); + + /* Local stuff */ + +-char path[] = "PATH=/bin:/usr/bin:/usr/ucb:/usr/bsd:/etc:/usr/etc:/usr/sbin"; ++char path[] = "PATH=/bin:/usr/bin:/sbin:/usr/sbin"; + + #define TIME_LIMIT 60 /* Do not keep listinging forever */ + #define INPUT_LENGTH 100000 /* Do not keep listinging forever */ + #define LINE_LENGTH 128 /* Editors can choke on long lines */ + #define FINGER_PROGRAM "finger" /* Most, if not all, UNIX systems */ + #define UNPRIV_NAME "nobody" /* Preferred privilege level */ +-#define UNPRIV_UGID 32767 /* Default uid and gid */ ++#define UNPRIV_UGID 65534 /* Default uid and gid */ + + int finger_pid; ++int allow_severity = SEVERITY; ++int deny_severity = LOG_WARNING; + + void cleanup(sig) + int sig; +diff -Naur tcp_wrappers_7.6/scaffold.c tcp_wrappers_7.6.gimli/scaffold.c +--- tcp_wrappers_7.6/scaffold.c 1997-03-21 12:27:24.000000000 -0600 ++++ tcp_wrappers_7.6.gimli/scaffold.c 2002-01-07 08:50:19.000000000 -0600 +@@ -180,10 +180,12 @@ + + /* ARGSUSED */ + +-void rfc931(request) +-struct request_info *request; ++void rfc931(rmt_sin, our_sin, dest) ++struct sockaddr_in *rmt_sin; ++struct sockaddr_in *our_sin; ++char *dest; + { +- strcpy(request->user, unknown); ++ strcpy(dest, unknown); + } + + /* check_path - examine accessibility */ +diff -Naur tcp_wrappers_7.6/socket.c tcp_wrappers_7.6.gimli/socket.c +--- tcp_wrappers_7.6/socket.c 1997-03-21 12:27:25.000000000 -0600 ++++ tcp_wrappers_7.6.gimli/socket.c 2002-01-07 08:50:19.000000000 -0600 +@@ -76,7 +76,11 @@ + { + static struct sockaddr_in client; + static struct sockaddr_in server; ++#if !defined (__GLIBC__) + int len; ++#else /* __GLIBC__ */ ++ size_t len; ++#endif /* __GLIBC__ */ + char buf[BUFSIZ]; + int fd = request->fd; + +@@ -224,7 +228,11 @@ + { + char buf[BUFSIZ]; + struct sockaddr_in sin; ++#if !defined(__GLIBC__) + int size = sizeof(sin); ++#else /* __GLIBC__ */ ++ size_t size = sizeof(sin); ++#endif /* __GLIBC__ */ + + /* + * Eat up the not-yet received datagram.
