Hello,
When I run v4admind and use the Kerberos 4 kpasswd client, I
get the error message:
Jun 29 17:53:57 dark ./v4kadmind[8490]: processing request:
Checksum does not match
I replaced the #defines of four_bytes_vax_to_nets and
two_bytes_vax_to_nets in lib/des425/quad_cksum.c with the
corresponding subroutines from the Kerberos 4 distribution (from
the MSBFIRST part of the #ifdef). This fixes the checksum problem.
I'm sorry I don't have a patch for this, but I'm not sure what to
use as the test for big/little endian-ness.

=========================================================================
Comment these out:
#define four_bytes_vax_to_nets(x) (((x[3]<<8|x[2])<<8|x[1]<<8)|x[0])
#define two_bytes_vax_to_nets(x) ((x[1]<<8)|x[0])
And add these:
static unsigned short two_bytes_vax_to_nets(p)
char *p;
{
union {
char pieces[2];
unsigned short result;
} short_conv;
short_conv.pieces[0] = p[1];
short_conv.pieces[1] = p[0];
return(short_conv.result);
}
static unsigned int four_bytes_vax_to_nets(p)
char *p;
{
static union {
char pieces[4];
unsigned int result;
} long_conv;
long_conv.pieces[0] = p[3];
long_conv.pieces[1] = p[2];
long_conv.pieces[2] = p[1];
long_conv.pieces[3] = p[0];
return(long_conv.result);
}
