several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.
We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.
- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.
- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.
- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.
- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.
- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.

.Sh DESCRIPTION
|
|
This set of functions assemble a simple table consisting of rows and
|
|
columns, allowing it to be printed with certain options. Typical use
|
|
would be output from tools such as
|
|
.Xr ls 1
|
|
or
|
|
.Xr netstat 1 ,
|
|
where you have a fixed number of columns, but don't know the column
|
|
widths before hand.
|
|
.Pp
|
|
A table is created with
|
|
.Fn rtbl_create
|
|
and destroyed with
|
|
.Fn rtbl_destroy .
|
|
.Pp
|
|
Global flags on the table are set with
|
|
.Fa rtbl_set_flags
|
|
and retrieved with
|
|
.Fa rtbl_get_flags .
|
|
At present the only defined flag is
|
|
.Dv RTBL_HEADER_STYLE_NONE
|
|
which suppresses printing the header.
|
|
.Pp
|
|
Before adding data to the table, one or more columns need to be
|
|
created. This would normally be done with
|
|
.Fn rtbl_add_column_by_id ,
|
|
.Fa column_id
|
|
is any number of your choice (it's used only to identify columns),
|
|
.Fa column_header
|
|
is the header to print at the top of the column, and
|
|
.Fa flags
|
|
are flags specific to this column. Currently the only defined flag is
|
|
.Dv RTBL_ALIGN_RIGHT ,
|
|
aligning column entries to the right. Columns are printed in the order
|
|
they are added.
|
|
.Pp
|
|
There's also a way to add columns by column name with
|
|
.Fn rtbl_add_column ,
|
|
but this is less flexible (you need unique header names), and is
|
|
considered deprecated.
|
|
.Pp
|
|
To add data to a column you use
|
|
.Fn rtbl_add_column_entry_by_id ,
|
|
where the
|
|
.Fa column_id
|
|
is the same as when the column was added (adding data to a
|
|
non-existent column is undefined), and
|
|
.Fa cell_entry
|
|
is whatever string you wish to include in that cell. It should not
|
|
include newlines.
|
|
For columns added with
|
|
.Fn rtbl_add_column
|
|
you must use
|
|
.Fn rtbl_add_column_entry
|
|
instead.
|
|
.Pp
|
|
.Fn rtbl_new_row
|
|
fills all columns with blank entries until they all have the same
|
|
number of rows.
|
|
.Pp
|
|
Each column can have a separate prefix and suffix, set with
|
|
.Fa rtbl_set_column_affix_by_id ;
|
|
.Fa rtbl_set_column_prefix
|
|
allows setting the prefix only by column name. In addition to this,
|
|
columns may be separated by a string set with
|
|
.Fa rtbl_set_separator ( Ns
|
|
by default columns are not seprated by anything).
|
|
.Pp
|
|
The finished table is printed to
|
|
.Fa file
|
|
with
|
|
.Fa rtbl_format .
