ssh server without auth (no auth server/client)

Well I have a Mac OS and Ubuntu.

My ubuntu have sshd - server.


I didn't want no autentification on ssh server.



Introdution and overview about keygen

if you want no auth in ssh server, you need access on your ssh server to change some configs.
If it is a public server (like hosting servers ) configs on server should be done.

Only need to upload your key.

How to say to ssh server that it's my machine trying login?

Client generate a private and public key. You share public key with server.
private and public key matches by algorithm and it's authentication.

So server recognize the keys and doesn't ask password.



How to do that?

Server

Edit /etc/ssh/sshd_config

Change some configs to:

RSAAuthentication yes
PubkeyAuthentication yes
ChallengeResponseAuthentication no
PasswordAuthentication no
UsePAM no

Reload server:

sudo /etc/init.d/ssh reload

Client

Gerate key:

ssh-keygen -q -f id_rsa -t rsa

scp ~/.ssh/id_rsa.pub user@server:~/.ssh/id_rsa.pub
ssh user@server
cd .ssh
cat id_rsa.pub>>authorized_keys
rm id_rsa.pub
exit

do same on server if you wish.


AutentificationTroubles?

Put this at server:

server$ chmod go-w ~/
server$ chmod 700 ~/.ssh
server$ chmod 600 ~/.ssh/authorized_keys

Doesn't it works?

cat /var/log/auth.log and grep it!

Bugs report to me

mercurial && svn -- is it usefull?

Hi all.

Yesterday I was talking with Bartosz ( a friend from Poland) and we're discussing about svn and mercurial. I never had used mercurial before.

Before begin technical skills to do that I need to explain situation.
If you're developer of a application that use svn and you have two computers, and you want to sync code but you can't commit it online. So mercurial it's a nice shot. I'm shipping with it.

In my example I have a desktop and a laptop (macbook) and I development lot of time in Desktop but some times I like to continue coding without commit and without copy the files by other system.

So how I can do that?

Syncing folder between a Mac and a Linux computer


What do you need?
- mercurial
- ssh server

It's easy.

In Desktop computer:

$ cd root_svn_directory
$ hg init
you need to write a similar file here:
bastiao@bastiao-desktop:~/root_svn_directory$ cat .hg/hgrc
[ui]
username = Your name - desktop
bastiao@bastiao-desktop:~/root_svn_directory$

And you need to wrote .hgignore. The sample it's for python. It's extension to ignore. In my case I want to ignore .svn and pyc (byte compile) files.

bastiao@bastiao-desktop:~/root_svn_directory$ cat .hgignore
syntax: glob
*~
*.pyc
*.svn
bastiao@bastiao-desktop:~/root_svn_directory$

Nice in desktop.


Let's to laptop:

hg clone ssh://user@ip_or_host/root_svn_directory

add contents in .hg/hgrc similar of the desktop file

it's done

Now you only to do on server:

hg update
hg commit -m "message"

on the other computer, clients:

commit:
hg commit -m "message"
sync server: (push to server)
hg push

to update:
hg pull
hg update

Thanks Bart!

if u have Bus Error:
disable sqlite : deactive (...)
http://trac.macosforge.org/projects/macports/ticket/12543

svn co http://svn.umitproject.org/svnroot/umit/trunk umit

cd umit

and install py2app
go to umit dir and run:
python2.5 umit

Primeira experiencia com mac...(draft)

Aproveito para cumprimentar todos os visitantes deste novo blog!

Este é a minha experiência com Macbook. Mais propriamente a minha primeira experiência com o Mac OS.


Estou a escrever no editor de texto e confesso que ainda tive de procurar ate o encontrar. Também foi a primeira vez que olhei para isto. Na altura nem sabia que as Applicações estavam num unico directorio.


Enfim recebi a encomenda, excelente, ligaram-me para confirmar a morada.

Recebi, tirei da caixa...

Retirei a bateria e configurei o OS X. Era quase o meu primeiro contacto com o Mac OS.. Fiquei absolutamente espantado não apenas com o Sistema Operativo em si ( baseado num antigo conhecido meu: UNIX ) mas também com o portátil em si. Trazia um comando, não resisti a experiência. Carreguei no menu e apareceu o Front-Row. Na altura nem o conhecia mas comecei a ver que era excelente a maneira com que eu poderia trabalhar no meu portátil. Peguei na maquina fotográfica e fui descarregar algumas fotos e fiquei a conhecer o iPhoto. Excelente programa para organizar fotografias. Voltei ao Front Row e comecei a ver as fotografias. Estava espantoso. Ponto complicado da coisa: onde estava a botão direito do touchpad? Ok. Descobri que tinha de carregar: Ctrl + Click e ele aparecia. Existe um monte de combinações de teclas possíveis inclusive utilizando a tecla Fn.

E como Hibernar?

Bem existe o safe sleep. Tipicamente é só fechar a tampa e ele hiberna.



Algumas configurações do modo sleep:


Abrir um terminal que fica em Aplicações -> Utilitários -> Terminal e colocar o seguinte comando,

sudo pmset -a hibernatemode 1

depois é reiniciar e quando fechas a tampa ao macbook ele hiberna.

Para suspender:

sudo pmset -a hibernatemode 0

Para voltar ao padrão:

sudo pmset -a hibernatemode 3

Já agora para copiar não se usa Ctrl + C nem Ctrl + V para colar, usa-se a tecla: "cmd".


(...) falar mais de safe sleep



Um aspecto importante também é que quando uma aplicação no Mac OS crasha (sim é raro mas pode acontecer, não é problema do Sistema Oprativo mas sim da aplicação) vai-se à dock, botão direito do rato e faz-se "Forçar Saida".


The only FREE way I have figured out how to do it is:


1. Install X11

2. Install Darwine

3. Download MagicISO

4. Open Winehelper (it's in the Darwine folder)

5. Using Winehelper, open the MagicISO installer

6. Install MagicISO

7. Using Winehelper, open MagicISO

8. Under 'Tools' Select 'Decompress UIF files' Select the UIF file you want to convert and hit 'Decompress.' It will output as an ISO. You can then use Disk Utility to open or burn the ISO."

Tipicamente depois de instalar o Darwin podemos emlar algumas aplicações do Windows.

(... ) Tweaks para Mac OS.. instalar apps, filmes etc.. acrescentar dps..


Estava na hora de verificar o mito: Pode o Macbook suportar Triple Boot?

Visto que sou estudante, iria precisar do Windows e de uma distribuição GNU/Linux.

Escolhi o Windows XP Corp SP2, e o Ubuntu 7.10 amd64 bits (Atenção, penso que e importante tratar-se da versão 64bits , por causa de alguns drivers ).



Primeiro passo: Instalar um bootloader: refit





Antes disto eu instalei uns updates ao Kernel,


deb http://ppa.launchpad.net/chrisirwin/ubuntu gutsy main

deb-src http://ppa.launchpad.net/chrisirwin/ubuntu gutsy main

Now update:

sudo apt-get update

sudo apt-get upgrade





woww.. it works (Macbook with Broadcam 4328 Wifi working - yes ):
