Converting Perforce depots to Mercurial repositories with hg convert

Converting Perforce to Mercurial repositories is fast (4-5 seconds for a 500MB repository with 300 revisions).

You'll also want to start p4d and log into P4V before, so it caches credentials.

1. Setup your p4 client:

export P4PORT=localhost:1666

export P4CLIENT=your_client_here

2. Enable hg converter by adding to ~/.hgrc

[extensions]

hgext.convert=

3. Start p4d

./p4d &

4. Convert the depot:

You need to specify a revision. Look it up in the p4 client (depot-details-revision). @all might also work.

hg convert //depot/...@307 converted-perforce path/to/hg-repo

5. Look at the history

hg history

6. Look at diffs and history with a graphical tool. This should give you a better idea of branches and such.

hgview

7. Clone your repository

hg clone /path/to/hg-repo

8. Publish your repository via the web interface

hg serve

9. Browse around

http://localhost:8000/

Additional notes:

Keep an eye on:

Share GNU screen sessions with a different user

Here's something cool you can do with screen. Share a screen session with multiple terminals. "screen -x". Of course, this only works if you're using the same user.

Let's say you want to do some cooperative debugging with another username. Simple:

1. Set screen setuid flag:

chmod +s screen

2. Start a new screen sessions:

screen -S mihai

3. Set multiuser

Ctrl-A

:multiuser on

4. Add the user to join your session to the ACL list:

Ctrl-A

:acladd jimbo

5. Now connect as jimbo and join cmihai's session (called mihai):

screen -x cmihai/mihai

Now you can share you screen session with that user :-).

Unpack functions and BSDProgress - progress bar for your archives.

A colored unpack script using bar:

A little KSH93 function for your .profile. Now you can augomatically unpack most archives while watching the pretty progress bar.

You need bsdprogress (Solaris and Linux port of NetBSD's progress). With a bit work it also works on AIX.

I just re-wrote this for progress, so I didn't check the cpio and such yet.

# Mihai Criveti - Unpack function:
# Progress Unpack - unpack using GNU tar and bsdprogress.
function up {
for archive in $*; do
 print $archive;
 case $archive in
      (*.tar) progress -f $archive gtar xpif - ;;
      (*.tar.gz) progress -f $archive gtar -zpixf - ;;
      (*.tgz) progress -zf $archive gtar -ipxf - ;;
      (*.tar.bz2) progress -f $archive gtar -jipxf - ;;
      (*.tbz) progress -f $archive gtar -jipxf - ;;
      (*.gz) progress -f $archive gunzip -;;
      (*.bz2) progress -f $archive bunzip -;;
      (*.tar.Z) uncompress -c $archive | tar gxvf - ;;
      (*.cpio) cpio -icd < $archive ;;
      (*.Z) uncompress $archive ;;
      (*.rar) unrar x $archive ;;
      (*.zip) unzip $archive ;;
 esac
done
}

Let's say we want to unpack files that end in *bz2 (it will automagically detect .tar.bz2 or tbz2), *gz and a specific tar archive:


cmihai@phobos:/home/cmihai/build$ up g*bz2 c*gz Python\-3.0.1.tar
gnupg-1.4.10.tar.bz2
100% |**********************************************************************|  3330 KB  296.95 KB/s    00:00 ETA
gnupg-2.0.14.tar.bz2
100% |**********************************************************************|  3888 KB  340.20 KB/s    00:00 ETA
ccache-2.4.tar.gz
100% |**********************************************************************| 86363     201.51 KB/s    00:00 ETA
Python-3.0.1.tar
91% |********************************************************               | 43320 KB  787.63 KB/s    05:00 ETA

See:

http://netbsd.gw.com/cgi-bin/man-cgi?progress++NetBSD-current

http://mac.freshmeat.net/projects/bsdprogress/

It builds fine on AIX (Makefile tweaks), Solaris and Linux. Native on NetBSD.

UNIX colors and tools

Just opened a new package of colored chalk so I'll write on my blackboard :-).

Can't really have fun without:

OpenSSH
GNU screen
KornShell 93, AWK, 1003.1 Shell & Utilities
Emacs, ed
Mutt
Midnight Commander (mc)
Elinks
Terminus font (sure, it's not a tool, but it sure as hell helps , especially during those 20 hour debugging sessions).

Emacs linum plugin + a 256 color TERMINFO entry + transparent putty can look pretty good:

256 colors _really_ do make quite a difference in Emacs (and vim) btw. Normal dtterm or xterm-color get you the first 8...

All you really need to do to get this working on AIX is to add a new TERMINFO entry (tic). You can easily grab the 256 color xterm with infocmp..

/usr/bin/tput colors
256

VIM looks pretty good too with a 256 color theme also (inkpot):

Disable OpenSolaris Network Auto-Magic (NWAM)

NWAM is now enabled by default, but it has some limitations (only one NIC is enabled, etc). Personally, I like to configure the network interfaces myself.

To disable Network Auto-Magic on SXCE (Solaris Express Community
Edition) or Indiana (OpenSolaris):

# svcadm disable svc:/network/physical:nwam

Custom df (diskfree) column output in Solaris using nawk

Let's say you want to combine some features of "df -h" with "df -n" to show filesystem type and some other custom modifications to the output. This is where awk/nakw/gawk/whatever come in handy:

% df -g | nawk '{if (NR % 5 == 1) printf "%-22s", $1 ; if (NR % 5 == 4) printf "%-10s", "fstype " $1 "\n"; if (NR % 5 == 2) printf "%-30s",$1/2/1024/1024 " GB"; if (NR % 5 == 2) printf "%-30s", $4/2/1024/1024 " GB free "}'

/	33.6627 GB	18.4351 GB free	fstype ufs
/devices	0 GB	0 GB free	fstype devfs
/system/contract	0 GB	0 GB free	fstype ctfs
/proc	0 GB	0 GB free	fstype proc
/etc/mnttab	0 GB	0 GB free	fstype mntfs
/etc/svc/volatile	7.88214 GB	7.8813 GB free	fstype tmpfs
/system/object	0 GB	0 GB free	fstype objfs
/lib/libc.so.1	33.6627 GB	18.4351 GB free	fstype ufs
/dev/fd	0 GB	0 GB free	fstype fd
/tmp	7.88142 GB	7.8813 GB free	fstype tmpfs

/export/home	74.4858 GB	1.87458 GB free	fstype ufs
/storage	108.639 GB	66.9259 GB free	fstype nfs

You can also add a comma (,) to the separators and output > csv (you can open the comma separated values table in Excel or OpenOffice or any other Spreadsheet application) :-).

OpenBSD Web Portal server (Drupal)

Configuring an OpenBSD Web Portal server Running Drupal on chrooted Apache + MOD_SSL + PHP + MySQL or PostgreSQL

Final goal: Drupal Web portal with TinyMCE JavaScript editor, Unicode and Locales support running on OpenBSD 4.3.

1. Installing and configuring OpenBSD – read the FAQ, partition.

a. You can install OpenBSD via cdrom (install43.iso or cd43.iso for netinstall) or netboot via TFTP / BOOTP / DHCPD. Read diskless(8) for details. On Windows, you can use TFTPD32 for DHCP/TFTP.

b. Partition the disk (read the FAQ on partitioning). Example partitioning scheme:

Partition	Mount location	Filesystem	Mount options
/dev/sd0a	/	ffs	rw,softdep	1 1
/dev/sd0b	swap	swap
/dev/sd0c	Whole disk
/dev/sd0d	/tmp	ffs	rw,softdep,nodev,nosuid	1 2
/dev/sd0e	/var	ffs	rw,softdep,nodev,nosuid	1 2
/dev/sd0f	/usr	ffs	rw,softdep,nodev	1 2
/dev/sd0g	/home	ffs	rw,softdep,nodev,nosuid	1 2

c. Disable non-critical services (like ident, time, daytime, etc.) from /etc/inetd.conf. Just comment out the lines you don’t want with a #.

d. Make sure you enable Soft Updates (softdep) mounts – they increase the Filesystem performance tenfold when it comes to writing a lot of small files. This is done by adding “softdep” to mount options in /etc/fstab.

e. Add a regular user account. You can use the useradd(8) script. Make sure you add the user to the wheel group to allow su – root.

f. For added security configure „sudo” by running visudo(8). You can permit all users in the wheel group to sudo root: %wheel ALL=(ALL) NOPASSWD: SETENV: ALL

i. It’s usually best to disable root logins and use “sudo” for root access (sudo –i or su – if you need a root sheel). Edit /etc/ssh/sshd_config. You can also change the default ssh port from 22 to some random port to mitigate against brute force attacks. Keeps them from filling out your logs with junk. Consider using ssh keys also.

ii. Port 6969

iii. PermitRootLogin no

iv. Restart the OpenSSH daemon: „pkill –HUP sshd”

g. Configure your user profile to use a ftp mirror. Add the following to your ~/.profile: (or whatever shell you’re using, eg: .bashrc, .zshrc): PKG_PATH=ftp://ftp.su.se/pub/OpenBSD/4.3/packages/i386/; export PKG_PATH

h. Restart the system (to mount softdep, etc.).

i. Install some “critical” packages:

i. pkg_add -vi mc zsh screen elinks zip unzip bzip2

j. Install ports

i. cd /usr
sudo ftp ftp://ftp.su.se/pub/OpenBSD/4.3/ports.tar.gz
sudo tar zxf ports.tar.gz

k. Unpack the OpenBSD source code (src and kernel – sys) – these are required for patching OpenBSD:

i. cd /usr/src
sudo ftp ftp://ftp.su.se/pub/OpenBSD/4.3/src.tar.gz
sudo ftp ftp://ftp.su.se/pub/OpenBSD/4.3/sys.tar.gz
sudo tar zxvf src.tar.gz
sudo tar zxvf sys.tar.gz

l. Apply OpenBSD security patches. You download patches from http://www.openbsd.org/errata43.html and you apply them using the instructions in the patch headers:

i. ftp ftp://ftp.openbsd.org/pub/OpenBSD/patches/4.3.tar.gz
You can put 001_openssh.patch, 002_openssh2.patch and the following patches in /usr/src and apply them. Read the header for the patches for instructions.

% head -11 001_openssh.patch
Apply by doing:
cd /usr/src
patch -p0 < install ="="> lib

===> scard
install -c -m 444 -o root -g bin Ssh.bin /usr/libdata/ssh

2. Restart the system to apply patches (or just the affected services by using pkill –HUP for example if you didn’t patch the kernel).

3. Installing additional OpenBSD filesets if required by say php5-gd: (if you skipped this at install). You can read the FAQ, but this is basically it:

a. % cd / && sudo ftp ftp://ftp.su.se/pub/OpenBSD/4.3/i386/xbase43.tgz
% sudo tar xzvphf xbase43.tgz

% sudo ldconfig -m /usr/X11R6/lib

4. Install PHP 5 (and various libraries for image manipulation, database access and Unicode support):

a. % sudo pkg_add -vi php5-core php5-mysql php5-curl php5-mbstring php5-gd
Ambiguous: choose package for php5-gd
0:
1: php5-gd-5.2.5
2: php5-gd-5.2.5-no_x11
Your choice: 1
parsing php5-gd-5.2.5

b. Activate PHP modules by creating the various symbolic links:

i. % sudo ln -s /var/www/conf/modules.sample/php5.conf /var/www/conf/modules

ii. % sudo ln -fs /var/www/conf/php5.sample/curl.ini /var/www/conf/php5/curl.ini

iii. % sudo ln -fs /var/www/conf/php5.sample/gd.ini /var/www/conf/php5/gd.ini

iv. % sudo ln -fs /var/www/conf/php5.sample/mbstring.ini /var/www/conf/php5/mbstring.ini

v. % sudo ln -fs /var/www/conf/php5.sample/mysql.ini /var/www/conf/php5/mysql.ini

5. Install, configure and secure the MySQL database:

a. % sudo pkg_add -vi mysql-server

b. Installing the default database

i. % sudo /usr/local/bin/mysql_install_db

c. Starting the MySQL service:

i. % sudo /usr/local/bin/mysqld_safe&
[1] 32390
% Starting mysqld daemon with databases from /var/mysql

d. Secure the installation (delete anonymous users, the test database and set a root password). PS: don’t use # in your password, there’s a bug in the script. Set that manually if you want.

i. % sudo /usr/local/bin/mysql_secure_installation

e. Tune some sysctl parameters for MySQL:

i. Edit /etc/sysctl.conf:
kern.shminfo.shmall=32768
kern.maxfiles=8192

ii. Apply the changes
% sudo sysctl kern.shminfo.shmall=32768
kern.shminfo.shmall: 8192 -> 32768
% sudo sysctl kern.maxfiles=8192
kern.maxfiles: 3580 -> 8192

iii. Add a mysql login in /etc/login.conf:
mysql:\
:openfiles-cur=1536:\
:openfiles-max=3096:\
:tc=daemon:

iv. % sudo cap_mkdb /etc/login.conf

6. Configure SSL (Secure Sockets Layer) for Apache mod_ssl (https). Generate a self signed certificate (or sign one) by reading ssl(8).

a. % sudo openssl genrsa -out /etc/ssl/private/server.key 1024
% sudo openssl req -new -key /etc/ssl/private/server.key -out /etc/ssl/private/server.csr
% sudo openssl x509 -req -days 365 -in /etc/ssl/private/server.csr -signkey /etc/ssl/private/server.key -out /etc/ssl/server.crt

b. Test SSL support (lynx is ssl enabled):
% sudo apachectl startssl
% lynx https://localhost

7. Configure the Apache webserver:

a. Edit the Apache configuration file and setup PHP and server details /var/www/conf/httpd.conf
AddType application/x-httpd-php .php
ServerAdmin cmihai@website
DirectoryIndex index.html index.php
ServerName hostname(fqdn)

b. Configure PHP:

i. Edit the PHP config /var/www/conf/php.ini
upload_max_filesize = 12M

c. Test PHP:
ed /var/www/htdocs/index.php
a

Test PHP:
.
w
q
% lynx http://localhost/index.php

d. Configure Sendmail for supporting the Apache chroot[1]
% sudo pkg_add -vi mini_sendmail-chroot
parsing mini_sendmail-chroot-1.3.6p0
mini_sendmail-chroot-1.3.6p0: complete

% sudo mkdir -p /var/www/usr/sbin/
% sudo ln /var/www/bin/mini_sendmail /var/www/usr/sbin/sendmail
% sudo cp /bin/sh /var/www/bin

8. Configure services to start at boot (Apache and MySQL):

a. % sudo ed /etc/rc.conf
httpd_flags="-DSSL"

b. % sudo ed /etc/rc.local
if [ -x /usr/local/bin/mysqld_safe ] ; then
su -c mysql root -c '/usr/local/bin/mysqld_safe >/dev/null 2>&1 &'
echo -n ' mysql'
fi
# Crearea unui link pentru socketul MySQL in chrootul Apache
mkdir -p /var/www/var/run/mysql
sleep 5
ln -f /var/run/mysql/mysql.sock /var/www/var/run/mysql/mysql.sock

c. Reboot to test changes.

9. Crate a database for Drupal and a user. Grand permissions:

a. % sudo mysql -u root -p
CREATE USER drupal IDENTIFIED BY 'password';
CREATE DATABASE drupal CHARACTER SET utf8;
GRANT ALL PRIVILEGES ON drupal.* to USER drupal@localhost IDENTIFIED BY 'password';

10.Install Drupal and modules:

a. % sudo pkg_add -vi drupal5-tinymce drupal5-link-to-content drupal5-imce drupal5-image drupal5-backup-migrate drupal5-autolocale drupal5-token drupal5-securelogin ImageMagick

11.Optionally configure .httauth for security:

a. % cd /var/www
% sudo htpasswd -c htpasswd username

Add .htaccess to /var/www/htdocs
AuthName "Nu este permis accesul"
AuthType Basic
AuthUserFile ../htpasswd
require valid-user

b. Add “Add AllowOverride All” în /var/www/conf/httpd.conf.

c. Restart Apache (apachectl stop && apachectl startssl).

You can now configure Drupal and the various modules. Be sure to setup a backup schedule. You can use the Drupal database backup and restore module.

You can also install Apache mod_security for additional security:
% sudo pkg_add -vi modsecurity-apache
% sudo /usr/local/sbin/mod_security-enable
% sudo apachectl stop && sudo apachectl startssl

Make sure you read /usr/local/share/doc/mod_security/modsecurity-manual.pdf

You should also keep an eye on your webserver. For monitoring, I recommend top(1), vmstat, (8), sysctl hw, pftop and mytop.

% sudo pkg_add -vi mytop pftop
% sudo /usr/local/sbin/pftop

To use mytop you'll need a ~/.mytop file (and set proper permissions on it). You can add something like:

prompt=1
pass=
user=drupal
db=drupal
delay=5
port=3306
socket=
batchmode=0
header=1
color=1
idle=1

% mytop

MyTOP in Action

You'll also want to setup Packet Filter. Read the PF User's Guide, pf.conf(5) and the example rulesets in /usr/share/pf/examples. Enable pf in /etc/rc.conf (pf=YES).

[1] Read chroot(2) ssl(8) afterboot(8), etc.

Convert NRG images to ISO images (nrg2iso) using dd

If you want to convert Nero "nrg" images to ISO format to mount or burn you can either use nrg2iso, or just use dd to skip the 300k header (will work just fine for DAO images):

dd if=image.nrg of=image.iso bs=4096 skip=75

C Programming under Tru64 UNIX

A crash course in C programming under Tru64 UNIX :-). You've got a text editor - ed(1), of course, make(1), install(1) and a C compiler - cc(1) - and you're good to go.

Don't like ED? Well, Tru64 also comes with vi and XEmacs by default, so no worries.

All you need to do now is write a Makefile:

% ed Makefile
a
CC=cc

hello: hello.o
$(CC) -o $@ $<

hello.o: hello.c
$(CC) -c -o $@ $<

clean:
rm -f hello hello.o
.
w
q

% make
cc -c -o hello.o hello.c
cc -o hello hello.c
% ls
Makefile hello hello.c
% hello
Hello, Tru64 UNIX!
% make clean
rm -f hello hello.o
% ls
Makefile hello.c

Building Git Version Control System on AIX, HP-UX and Solaris

Git is a fast version control system originally designed for the Linux kernel and written by Linus Torvalds.
Need git on AIX or HP-UX? Here's how:

HP-UX PA-RISC 2.0:

First, you're going to need a compiler (GCC), GNU make (gmake) and GNU coreutils (install). swinstall the dependency repositories first:
coreutils 6.9 coreutils
gcc 4.2.3 gcc
libgcc 4.2.3 libgcc
libiconv 1.12 libiconv
make 3.81 make
perl 5.8.8 perl
zlib 1.2.3 zlib

Untar the package and start building:

$ ./configure --with-iconv=/usr/local/bin

Edit the Makfile:

CC = gcc
AR = ar
RM = rm -f
TAR = tar
FIND = find
INSTALL = /usr/local/coreutils/bin/install

# sudo gmake NEEDS_LIBICONV=1 NO_TCLTK=1 install prefix=/usr/local

$ which git
/usr/local/bin/git
$ uname -sr
HP-UX B.11.11
$ git --version
git version 1.5.4.4

Building GIT on AIX 5.3 POWERPC:

Install dependencies and GCC, gmake, GNU coreutils (install), etc:

gcc-4.0.0-1 libgcc-4.0.0-1 libstdc++-4.0.0-1 libstdc++-devel-4.0.0-1 gcc-c++-4.0.0-1 readline-4.3-2 readline-devel-4.3-2 zlib-1.2.3-3 zlib-devel-1.2.3-3 make-3.80-1 unzip-5.51-1 flex-2.5.4a-6 bison-1.875-3 popt-1.7-2 gettext-0.10.40-6 expect-5.42.1-3 tcl-8.4.7-3 tk-8.4.7-3 coreutils-5.2.1-2

$ ./configure

vi Makefile:

CC = /opt/freeware/bin/gcc
AR = ar
RM = rm -f
TAR = /opt/freeware/bin/tar
FIND = find
INSTALL = /usr/linux/bin/install
RPMBUILD = rpmbuild
TCL_PATH = /opt/freeware/bin/tclsh
TCLTK_PATH = /opt/freeware/bin/wish

# gmake NO_MSGFMT=1 install prefix=/opt/freeware

$ uname -a
AIX aix 3 5 004518FC4C00
$ which git
/opt/freeware/bin/git
$ git --version
git version 1.5.4.4

Solaris 10:

Solaris 10 comes with gcc, gmake and GNU tools in /usr/sfw/bin, but you'll need ginstall from GNU coreutils (you can get it from Solaris Freeware).

$ ./configure

Edit the Makefile - set the path to "ar", "gcc" and GNU "install".

ES40 - OpenSource Alpha AXP Emulator

I've already posted about other free Alpha or VAX emulators like PersonalAlpha (the free version of CHARON-AXP, also makers of CHARON-VAX) and SIMH. Now it's time for something open source, that will work on Windows and UNIX systems.

AlphaServer ES40 Emulator is a portable emulator for the HP (DEC, Compaq) AlphaServer ES40. The current version is capable of running OpenVMS with some limitations. The goal is to have a drop-in replacement for real ES40's. Emulates the Alpha AXP EV68CB processor and other devices.

Now you can run OpenVMS or Tru64 UNIX on your own personal computer.

The advantage of ES40 over PersonalAlpha is that you can emulate EV68 CPUs and a more modern system (AlphaServer ES40) and additional hardware. It's also open source, and will run on your Windows, Linux and UNIX machines. The problem is, it's no match for CHARON-AXP or PersonalAlpha in terms of performance.

You can even use ES40 to install other operating systems like BSD and Linux on Alpha.
Here's FreeBSD/alpha 6.3-RELEASE

VPNC - Open Source client for Cisco VPN Contentrator

Got an ASA, a PIX or some other VPN Concentrator (or even Juniper NetScreen)? Well, you'll run into some troubles sooner or later. The Cisco VPN Client doesn't support 64 bit Windows clients, x86 Solaris clients and is just a pain to use on Linux.

VPNC doesn't require any kernel modules. Just put the IPSec gateway IP, IPSec ID, IPSec secret and XAuth username into /etc/vpnc/default.conf and start vpnc. It should work instantly :-). No fuss, no mess.

It will work just fine on Solaris, Linux, MacOS X or BSD machines. You can even get it running on your Windows box (Cygwin libs).

Tunneling over ICMP, DNS, HTTP and HTTPS proxies

Stuck beyond a firewall, captive portal or proxy and need your ssh (or any other service)? Here's a few ways to tunnel out:

PTunnel - Tunnel TCP using ICMP echo request and reply packets (PING), includes authentication, allows for multiple connections.
Iodine - tunnel IPv4 data through a DNS server, allows for authentification.
NSTX - Tunneling network packets over DNS.
Corkscrew - tunneling SSH through HTTP proxies.
httptunnel - bidirectional virtual data connection tunnelled in HTTP requests.
gotthard - ssh through https proxy tunnel

I've already mentioned Shared Shell and such too :-).
