OpenBSD Description

The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography.OpenBSD project supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX. OpenBSD is freely available from our FTP sites, and also available in an inexpensive 3-CD set.

New functionality: · The libc resolver(3) may now be forced to perform lookups by TCP only using a new resolv.conf(5) option. The nameserver declaration in resolv.conf(5) has also been extended to allow specification of non-default nameserver ports. · apropos(1) has two new options (-S and -s) to allow searching by machine architecture and manual section. · aucat(1) now has audio server capability. Audio devices can be shared between multiple applications. Applications can run natively on fixed sample rate devices or on devices with unusual encodings. Multi-channel audio devices can be split into smaller independent subdevices. · aucat(1) now has a deviceless mode, in which it can be used as a general purpose audio file format conversion utility (to mix, demultiplex, resample or reencode files). · ifconfig(8) can now list channels supported by an IEEE 802.11 device. · New views were added to systat(8): malloc, bucket and pool.

OpenSSH 5.2: New features: · o Added an option to ssh(1) to force logging to syslog rather than stderr. · o The sshd_config(5) ForceCommand directive now accepts commandline arguments for the internal-sftp server. · o The ssh(1) ~C escape commandline now support runtime creation of dynamic port forwards. · o Support the SOCKS4A protocol in ssh(1) dynamic forwards. · o Support remote port forwarding with a listen port of '0'. · o sshd(8) now supports setting PermitEmptyPasswords and AllowAgentForwarding in Match blocks. The following significant bugs have been fixed in this release: · o Repair a ssh(1) crash introduced in openssh-5.1 when the client is sent a zero-length banner. · o The eow@openssh.com and no-more-sessions@openssh.com protocol extensions are now only sent to peers that identify themselves as OpenSSH. · o Avoid printing "Non-public channel" warnings in sshd(8), since ssh(1) has sent incorrect channel numbers since ~2004; make ssh(1) send the correct channel number for SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE. · o Avoid double-free in ssh(1) ~C escape -L handler. · o Correct fail-on-error behaviour in sftp(1) batchmode for remote stat operations. · o Avoid hang in ssh(1) when attempting to connect to a server that has MaxSessions set to zero. · Over 5500 ports, minor robustness improvements in package tools.
