Hi, Could you create a patch and submit a bugreport for this. Thanks, Jaap On Fri, 19 Feb 2010 10:22:07 -0500, "Jonathan Schilling" <jschilling () niksun com> wrote:
[Resending, since this has not shown up on the archive] In epan/dissectors/packet-kerberos.c, there is this code in a couple of places for beginning the -K keytab-file processing: /* should use a file in the wireshark users dir */ ret = krb5_kt_resolve(krb5_ctx, filename, &keytab); if(ret){ fprintf(stderr, "KERBEROS ERROR: Could not open keytab
file
:%s\n",filename); return; } ret = krb5_kt_start_seq_get(krb5_ctx, keytab, &cursor); if(ret){ fprintf(stderr, "KERBEROS ERROR: Could not read from
keytab
file :%s\n",filename); return; } The two error messages are a bit misleading. Per the KRB5 API doc at
http://www.ncsa.illinois.edu/UserInfo/Resources/Software/kerberos/krb5api/kr
b5api4.html and elsewhere, krb5_kt_resolve() does *not* try to open the keytab file, but rather just sees if the name is wrongly formatted. So
the
first message should be "Could not resolve keytab file ..." If the
keytab
filename is wrong, it will be detected in the call to krb5_kt_start_seq_get(). So the second message should be something like "Could not open or read from keytab file ...". Thanks, Jonathan Schilling
