Changes: The new program, shred, performs secure removal of files on a disk with a conventional file system. This version has bug fixes, better performance, is more POSIX- compliant, and is more portable.
Updated NFS-HOWTO - Near Final Draft - Please complain if you don't like somethingというリンクがあるのだが、誰か和訳やりません？
WinSCP is freeware SCP (Secure CoPy) client for Windows 95/98/2000/NT using SSH (Secure SHell). Its main purpose is safe copying files between local and remote computer. Beyond this basic function, WinSCP manages some other actions with files.TTSSH とこれで完璧？
the FreeBSD 3.x branch will continue to see vulnerability response only for remotely exploitable vulnerabilities. This eliminates support for the class of vulnerabilities exploitable by users with accounts on the system.むー。4.X に上げるのかなあ。でもおっかねえな...
fping is a ping(1) like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping. Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion. If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.
Unlike ping, fping is meant to be used in scripts and its output is easy to parse.
ssh -C -f -L 10023:remotehost:23 remotehost ping -i 60 localhost > /dev/null telnet localhost 10023で切断しないようになった。なるほどー。
ssh -C -f -L 10022:remotehost:22 remotehost ping -i 60 localhost > /dev/null slogin -p 10022 localhostによって日本語も通るようになった。 なんだかなーという気がしないでもないが(笑)、 まあ当分はこれでいけるかな。
#!/bin/sh
PORT=10022
HOST=fuga.hoge.jp
if ! (fuser -n tcp $PORT | grep -q $PORT) then
ssh -f -L $PORT:$HOST:22 $HOST ping -i 60 localhost >& /dev/null
fi
slogin -p $PORT localhost
if ! (ps a | grep -q "slogin -p $PORT") then
kill `fuser -n tcp $PORT | awk '{print $2}'`
fi
というスクリプトを書いてみた。ad hoc もいいところだが(笑)。
これで複数の slogin プロセスを走らせることができるようになった。
ポート決め打ちなのが気に入らないが、
まあこれ以上凝ってもしょうがなかんべ。

Studying foams might seem like a tasty job---whipped cream, chocolate mousse, and beer heads are foams--but engineering ideal foams is harder than tasting them. Foam researchers have learned that the bubbles in fresh foam enlarge over time, that the liquid between them drains out, and that these two processes affect each other. But they haven't had a detailed and accurate theory describing the interaction. Now a team reporting in the 14 May PRL has developed such a theory and shown that it agrees with their experiments. The theory is a step toward a more complete understanding of foams, with possible applications in areas from beer production to mineral purification. ( Sascha Hilgenfeldt et al., Phys. Rev. Lett. 86, 4704. )
Changes: This version features support for several new cards amd bridges, updates for many drivers, endianess fixes for embedded PowerPC boards (m8xx), and configuration and makefile fixes.
Changes: A Russian translation, various fixes to make Sketch work with Python 2.1, the SVG import filter has basic support for text and images, and bugfixes.
Changes: This release adds support for easy cloning of SCSI disks by giving "sd0" as the third argument to slurpdisk and uploaddisk. Also, support for i386 and i486 CPUs was added.
Changes: All occurrences of uint64_t were replaced with u_int64_t for glibc 2.0. /dev/rtc can be a module. It is no longer assumed that malloc(0) returns a pointer. Cross compile changes were made. A better explanation for rmmod -a was written. References to modules(2) were removed.
Changes: This release has many AI improvements, improved ko handling, and speedups through caching of data.ほー。

Tripwire Policy File Generator uses a Perl script - mktrippol.pl - that writes a Tripwire policy file from an existing Linux setup. While it targets ROCK Linux it can really be used for any system. The script reads its commands from a Tripwire policy file 'template' using name expansions. It has a few nice facilities like list expansion, directory walks, variable adding etc. Changes: This release includes directories and --prefix support for tripwire binaries.

ssh -f 16667:plumserver:6667 plumserver ping -i 60 localhost > /dev/nullしといて、ircat で localhost の 16667 へつなげばよろしい。 のだが、めんどいな。 シェルスクリプトから上記を実行→ircat を起動して、 ircat の終了と同時に ssh も殺すにはどう書くのが楽だろうか？
CONNECTING TO AN RSYNC SERVER
It is also possible to use rsync without using rsh or ssh
as the transport. In this case you will connect to a
remote rsync server running on TCP port 873.
You may establish the connetcion via a web proxy by set-
ting the environment variable RSYNC_PROXY to a host-
name:port pair pointing to your web proxy. Note that your
web proxy must allow proxying to port 873, this must be
configured in your proxy servers ruleset.
Changes: removal of the localhost special case of via (use plugin %h for talking to ssh instead), preventing POP3 code from authenticating multiple times on success, fixes for IMAP password shrouding, GCC warning cleanups, a fix for another hole that was letting zombies through, a SA_RESTART portability fix for SunOS, and ignoring Sender and Resent-Sender headers unless they contain @.
