<para>&man.config.8; now implements a <literal>nodevice</literal>

kernel configuration file directive that cancels the effect of a

<literal>device</literal> directive.</para>

|
<para>The <option>-N</option> and <option>-W</option> flags to

<para>&man.disklabel.8; is now only built for architectures where

it is useful (i386, pc98, alpha, and ia64).</para>

<para>The <option>-s</option> to &man.disklabel.8; has been

file.</para>

<para>&man.dump.8; now supports caching of disk blocks with the

<option>-C</option> option. This can improve dump performance
|

at the cost of possibly missing filesystem updates that occur
|
|
between passes.</para>
|

<para>&man.dumpfs.8; now supports a <option>-m</option> flag to

print file system parameters in the form of a &man.newfs.8;

<para>&man.elfdump.1;, a utility to display information about &man.elf.5;

<para>&man.ftpd.8; now supports a <option>-h</option> option to

&man.ftpd.8; version or hostname, in server messages.
|
|
&merged;</para>
|
|
|
|
<para>&man.ftpd.8; now supports a <option>-P</option> option to

specify a port on which to listen in daemon mode. The default

data port number is now set to be one less than the control port
|
|
number, rather than being hard-coded. &merged;</para>
|
|
|
|
<para>&man.ftpd.8; now supports an extended format of the
|
|
<filename>/etc/ftpchroot</filename> file. Please refer

|
to the &man.ftpchroot.5; manpage, which is now available,
|
|
for details. &merged;</para>
|
|
|
|
<para>&man.ftpd.8; now supports login directory pathnames
|
|
that specify simultaneously a directory for &man.chroot.2;
|
|
and that to change to in the chrooted environment. The
|
|
<literal>/./</literal> separator is used for
|
|
this purpose, like in other FTP daemons having this feature.
|
|
It may be used in both &man.ftpchroot.5; and &man.passwd.5;.
|
|
&merged;</para>
|
|
|

<para>&man.fwcontrol.8; now supports <option>-R</option> and
|
|
<option>-S</option> options for receiving and sending DV
|
|
streams. &merged;</para>
|
|
|
|
<para>&man.ipfw.8; now supports <literal>enable</literal> and
|
|
<literal>disable</literal> commands to control various aspects
|
|
of the operation of &man.ipfw.4; (including enabling and
|
|
disabling the firewall itself). These provide a more convenient
|
|
and visible interface than the existing sysctl
|
|
variables. &merged;</para>
|
|
|
|
<para>&man.kenv.1; has been moved from
|
|
<filename>/usr/bin</filename> to <filename>/bin</filename> to
|
|
make it available at times during system startup when only the
|
|
root filesystem is mounted.</para>
|
|
|
|
<para>The MAKEDEV script is now unnecessary, due to the mandatory
|
|
presence of &man.devfs.5;, and has been removed.</para>
|
|
|
|
<para>The &man.libgeom.3; library has been added to allow some
|
|
userland access to the &man.geom.4; subsystem.</para>
|
|
|
|
<para>&man.mount.nfs.8; now supports a <option>-c</option> to
|
|
avoid doing a &man.connect.2; for UDP mount points. This option
|
|
must be used if the server does not reply to requests from the
|
|
standard NFS port number 2049 or if it replies to requests using
|
|
a different IP address (which can occur if the server is
|
|
multi-homed). Setting the
|
|
<varname>vfs.nfs.nfs_ip_paranoia</varname> sysctl to
|
|
<literal>0</literal> will make this option the
|
|
default. &merged;</para>
|
|
|
|
<para>&man.newsyslog.8; now supports a <literal>W</literal> flag
|
|
to force previously-started compression jobs for an entry (or
|
|
group of entries specified with the <literal>G</literal> flag)
|
|
to finish before beginning a new one. This feature is designed
|
|
to prevent system overloads caused by starting several
|
|
compression jobs on big files simultaneously. &merged;</para>
|
|
|
|
<para>&man.pam.ssh.8; has been rewritten. One side effect of the
|
|
rewrite is that it now starts a separate instance of
|
|
&man.ssh-agent.1; for each session instead of trying to connect
|
|
each session to the agent started by the first session.</para>
|
|
|
|
<para>&man.ping.8; now supports a <option>-D</option> flag to set
|
|
the <quote>Don't Fragment</quote> bit on outgoing packets.</para>
|
|
|
|
<para>&man.ping.8; now supports a <option>-M</option> flag to use
|
|
ICMP mask request messages instead of ICMP echo requests.</para>
|
|
|
|
<para>&man.ping.8; now supports a <option>-z</option> flag to set
|
|
the Type of Service bits in outgoing packets.</para>
|
|
|
|
<para>&man.pw.8; can now add a user whose name ends with a
|
|
<literal>$</literal> character; this change is intended to help
|
|
administration of <application>Samba</application>
|
|
services. &merged;</para>
|
|
|
|
<para>A bug in &man.rand.3; that could cause a sequence to remain
|
|
stuck at <literal>0</literal> has been fixed. (&man.rand.3;
|
|
remains unsuitable for all but trivial uses.)</para>

<para>The seeding algorithm used by &man.srandom.3; has been
|
|
strengthened.</para>
|
|
|
|
<para arch="sparc64">The sunlabel utility, a program analogous to
|
|
&man.disklabel.8; that works on Sun disk labels, has been
|
|
added.</para>
|
|
|
|
<para>The &man.swapoff.8; command has been added to disable paging
|
|
and swapping on a device. A related &man.swapctl.8; command has
|
|
been added to provide an interface to &man.swapon.8; and
|
|
&man.swapoff.8; similar to other BSDs.
