What's in the SUNRUP.C file?

The sunrup.c file is the source code to the 'sunrup' command which I use to filter the 'rup' command.

The filter does two things. First, it changes the output of the rup command from:

     name uptime load-averages

     telnetable-url uptime load-averages

sunrup.c:

/* sunrup.c  - by Erik Seielstad <erik@acs.brockport.edu> */
/* --- a simple 'rup' filter for the Web. */
/* Disclaimer:  I make no claims that this program works.  Use at your */
/* Disclaimer:  own risk.                                              */
#include <stdio.h>

main()
{
char line[100];
char hname[15];

/*    printf("Content-type: text/html\n\n<pre>"); */

/* originally I planned on using the C program to add the header      */
/* information, but I chose to change that method, moving these two   */
/* outputs into the sunrup.cgi */
/* shell script. */


   gets(line); /* discards the RUP command's "collecting responses" line */

   while(gets(line))    /* while we receive lines from the 'rup' command */
     {
    strncpy(hname, line, 13);      /* grab first 13 characters of a line */
    hname[12] = '\0';              /* just to be safe, make sure we have */
                                   /* a NULL character at the end of out */
                                   /* string.  */

                                            /* remove leading whitespace */
    while (*hname == ' ') strcpy(hname, hname+1); 


                      /* if the name is NOT a host we are trying to hide */
    if ( (strcmp(hname, "startp.acs.b") != 0) )
    if ( (strcmp(hname, "starfish") != 0) )
    if ( (strcmp(hname, "stingray") != 0) )
      {
        /* print the anchor 'telnet' address then rest of the RUP output */
             /*  ** notice we need to quote the double-quotes in the URL */
    printf("<a href=\"telnet://%s.acs.brockport.edu/\">%12s</a>%s\n",
       hname, hname, line+13);
      }
     }

               /* unnecessary trailer stuff (like links back to my pages */
                     /* this could easily have gone in the shell script. */
   printf("</pre><hr><center>\n");
