Ubuntu 9.04 Jaunty Jackalope - NVidia TNT2 Model 64 32MB

Hi Guys,

I'm using Linux in a old PC and today I clean all old systems ( yeah I didn't clean the system since 5 years).

After install 9.04 I can't put 1024x768 resolution.

After google it I found a thread talking about it [1]

For me it is useful and then I publish it here. Even I want support to 3D acceleration I read that it's not possible (waiting for new hacks from nvidia team, but I'm guessing that is not incoming.)

VirtualBox

Hello,

Today I'd like to say that I'm using VirtualBox[1] - it is a very nice platform to run virtual machines, similar VMware but it is free.

It is a product from Sun.

How to mantain several branches tracking a trunk?

Last few years, I was working inside some projects (Umit and others).
When you work with other peoples commits are limited so the best idea is create a branch. But how I do that? From last few years I was thinking that svn doesn't have support branches, and the way to do that it's just copy the trunk and make "svn merge .." and keep update the branch.
Last month a guy named Guilherme, show me how I really make a branch inside Subversion.
It's not easy if you're working with old tracking. It's the reason of the post.

I would like to talk about:
- branches
- tags

There was a application 'svnmerge' available to create branches. So it keep branch tracking changes on trunk. That's really cool. Advantages?

How svnmerge works with old versions?

First you need to initialize the branches: svnmerge init PATH ( You should do it first at branch, later at trunk)


You can rollback some merges, sample: svnmerge rollback -M r100-120.

The team will take the real avantages after integration, or if you create svnmerge at begin.

In your branch, you can merge easy way: svnmerge merge, and optionally we can specify the revision interval, between revision x and revision y, -rx-y.

At trunk you should do same thing, to push branch changes:
svnmerge merge -S brach_directory

Easy? :D

Thanks Guilherme, it's really cool.

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!
