Original question:
Does anyone know I can see all of the machine name that is ouput in the
third column of the command "last".
Example of the output:
boudreau pts/13 cleopatre.pasteu Fri Apr 12 08:16 - 08:22 (00:06)
I know the data is kept in /var/adm/wtmpx but is not really
searchable.
-----------------------------------------------------------------------
Thank you to all that replyied.
The best solution was given by
scott hollatz <shollatz@d.umn.edu>
who wrote a small C program that reads /var/adm/wtmpx. We can
costumize the output by changing the program:
I wrote this as part of another project. It will read and display the
wtmpx
file, displaying the full host name. (I pipe the output of this
program to
another. Lines that have user names on them don't begin with a '.'.)
The following works for Solaris 2.3, 2.4, and 2.5.
-----------------------------------------------
/*

#include <stdio.h>
#include <utmpx.h>
#include <sys/time.h>

struct utmpx tmpx; /* data record */
time_t seconds;

char buff[ 32 ]; /* for time processing */

if ( !--argc )
{
fprintf( stderr, "use: stmpx file\n" );
exit( 1 );
}
fName = *++argv;
/* open the data file, read and print contents */
if ( !(f = fopen( fName, "r" )) )
{
fprintf( stderr, "cannot open %s\n", fName );
exit( 3 );
}
while ( !feof( f ) && fread( &tmpx, sizeof( struct utmpx ), 1,
f ) )
{
seconds = (time_t) tmpx.ut_tv.tv_sec;
t = localtime( &seconds );
/* build the time string in yyyymmdd.hhmmss format */
sprintf( buff, "%4d%02d%02d.%02d%02d%02d",
t->tm_year + 1900,
t->tm_mon + 1,
t->tm_mday,
t->tm_hour,
t->tm_min,
t->tm_sec );
printf( "%s %s %s %s\n",
tmpx.ut_user, buff, tmpx.ut_host, tmpx.ut_line
);
}
fclose( f );
}
