Lotus Notes 8.5 & Ubuntu 9.10

if you install the .deb file of Lotus Notes Client 8.5 in Ubuntu 9.10 everything will go fine, except that you will not see anything in the main window…It’s a problem related to an update of libgtk, you need the old files instead.

Easy solution:

1 – Download here the 4 files (courtesy of BenKevan/EclipseAgent)

2 – Copy them in /opt/ibm/lotus/notes

3 – Voilà.

Update the Nvidia Drivers with Ubuntu 9.10 (manual mode)

After upgrading to Ubuntu 9.10 my X server sometimes gave me a casually “Out of Range” message; I’ve installed the Nvdia drivers for my graphic card a few months ago (with Ubuntu 9.04) and the version 1.85 is probably not fully compatible with the new Karmic Koala. There are a lot of useful guides that let you know how to upgrade repositories and automate installation of drivers via apt-get…But I offer to you a fastest and very old-fashion style way:

1 – Remove the old drivers from System -> Administration -> Hardware Driver

2 – Download from Nvidia website the 1.90 software for Linux  (it’s a .run file, near 22-23 mb)

3 – Press CTRL+ALT+F1 for open a terminal session (don’t use your terminal link on desktop, it’s a different thing) and write your standard username/password

4 – Stop the X server with sudo /etc/init.d/gdm stop (Ubuntu will tell you that there are other commands, like service and stop for doing this, but this one will probably work;-))

5 – Manually go to the directory where you’ve saved the .run file

6 – Do sudo sh Nvidia bla bla bla etc etc etc.run 🙂

7 – Follow the onscreen instructions and at the end let the new Nvdia install to edit and change your graphic configuration

8 – Reboot with sudo shutdown -r now

9 – Voilà, if you go to System -> Administration -> Nvidia Server Settings you’ll see that the new drivers are on and you’ll can eventually make changes about resolution etc.

Ubuntu 9.10 – A Fast Review

I’ve just upgraded to Ubuntu 9.10 from 9.04, by using always the same method (via Administration->Update Manager) as in the past. The process took near 2 hours, with only a continous crash related to the Flash plugin. This new edition has some news, like:

1 – The Ubuntu Software Center:

usc

where you can download applications and at sametime watch what you’ve installed and eventually remove it. Very windows style. Very useless:-) I’m a little tired about “easy things for newbies”…If you’re a linux newbie you want to learn something new, different, open; you don’t need another win style computer!Past years Linux wasn’t user-friendly…Now it’s too much;-)

2 – Ubuntu One: 2gb of webspace for sharing and backup, directly accessible from desktop

one

3 – A lot of new screensavers/desktop images and themes

4 – A better support about Eucalyptus and private cloud (on server edition)

5- Open Office 3.1

Ubuntu is a must to have BUT before upgrading remember that:

1 – IMHO this edition is a little slower than 9.04, at least on my pc without a fresh install; startup and open applications remember to me the same “slowly feeling” I had when upgraded from 8.04 to 8.10 (is the .10 release always slower than .04???:-))
2 – My old Vmware Player 2.5.2 needed an update to 3.0 in order to work with new kernel (download the .bundle file on Vmware website and install it with sudo sh xxxxxx.bundle). The 3.0 is fantastic and it can create VM too!
3 – The Lotus Notes Client 8.5 doesn’t work with Ubuntu 9.10; a re-install didn’t fix it.

Break the 1%

Following this chart, Linux finally breaks the 1% wall regarding the percentage of different OS installed worldwide.
It’s nice but unfortunately it’s still really low!I’m pretty sure that during next years “Cloud OS” and web applications will have a lot of important in home and business environments. I hope in the future that all the OS will become unnecessary;-)  Imagine a sort of “Adobe Air” OS, where applications works at the same on every pc, without be worried about the maintenance and all the other stuffs…Could someone explain to me a thing: with supersolid Linux distros (and Ubuntu 9.04 is one of them!), with Win Xp still alive and strong (it’s like a phoenix after the diffusion of netbook) and a Win Vista absolutely usable, with all the wonderful enhancements of Snow Leopard (have you seen the new way for chinese characters input?!!)and with Google apps that do everything everywhere on every pc…WHO is interested in Win7?:-)

Fast ssh/sftp jail

In the last 48 hours I performed the installation of a large ftp/stp/ssh server; everything works ok except that, for some obscure reasons, I cannot deny to a connected user the access of the directories’ list; I’ve tried PureFtpd, Vsftpd, Proftpd and all the instructions related to chrooting an user by adding commands in the various configuration files…Don’t know why but it didn’t work!!It never happened before…So I think about another solution and…Voilà, ultrafast Ubuntu server with Proftpd and the hi-power of scponly:

1 – Install a Ubuntu server (preferably 8.04 or 8.10, for immediately install ssh server during the first process)

2 – Make a user during installation and leave all other settings by default

3 – Give to your server a static ip (sometimes ifconfig sucks, just in case install webmin and change the network from it using your browser) and do a sudo apt-get update

4 – Let’s do sudo apt-get install scponly

5 – Immediately reconfigure the software for the chroot version with sudo dpkg-reconfigure -plow scponly and answer “YES” to the menu

6 – Go to /usr/share/doc/scponly/setup_chroot and sudo gunzip the .gz file inside the directory

7 – Do sudo chmod + x setup_chroot.sh and launch it with sudo ./setup_chroot.sh

8 – Follow the instructions and add a totally new user (choosing the home and the incoming directory, the only one where the user can write!)

9 – Do sudo apt-get install proftpd and configure it by editing the /etc/proftpd/proftpd.conf (google for the configuration, but it’s sufficient to edit the name of the server, uncomment “DefaultRoot” and few others) and let’s restart it with sudo /etc/init.d/proftpd restart

10 – Log in with some sftp client like Filezilla to the hostname on port 22 with the username and password of the scponly user. Voilà, you see few directories, you cannot go anywhere and the only interesting thing is to up/down to the incoming dir;-)

Ultra Fast Japanese Scim for Ubuntu 8.04

After a fresh install of Ubuntu I always forget how to configure SCIM for input japanese in every application: after reading a lot of wiki and how to, removing 4 times scim and all related components, I’ve reached my goal with this ultra-fast passage (I’m pretty sure that not all the modules are useful, but it works for me perfectly in every software, even openoffice and skype) for scim with anthy (hope you have your repositories full updated and configured):

1 – Open a terminal and input:

sudo apt-get install scim-anthy im-switch scim-bridge-agent scim-bridge-client-gtk scim-bridge-client-qt scim-bridge-client-qt4 language-support-ja

This input install every type of scim-bridge, the framework im-switch and even the full japanese language support.

2 – Input:

locale

and remember the result: it’s sufficient to memorize the part after the “LANG” command, mine is “it_IT.UTF-8”

so input:

im-switch -z (your locale) -s scim (in my pc it’s im-switch -z it_IT.UTF-8 -s scim)

so scim knows about your keyboard default.

3 – Reset your X server with CTRL-ALT-BACKSPACE (pay attention, save your session and documents because it’s an instant reset!)

4 – Log in and right click on the scim keyboard icon in the taskbar, choose configuration and watch in global configuration (interface) if the keyboard layout selected is your DEFAULT keyboard layout (mine is italian) and in global configuration (IMEngine) if japanese is installed as input method.

5 – Close the window and try yourself in OpenOffice by activating scim with CTRL-SPACE. Hope it works!

My OS panel

I like minimalism (sometime) and after years I’ve reached the right panel for my Ubuntu 8.04 at work…There are all the things I need:-)

From the left:

1 – Firefox 3.0

2 – Gftp (a very useful ftp and especially ssh client)

3 – Putty (remote terminal on the servers I need)

4 – Krdc (remote access on client/servers, very useful for windows ones)

5 – OpenOffice 2.4 Writer

6 – OpenOffice 2.4 Calc

7 – Skype (last version for Linux is good enough)

8 – Gnome terminal, the most useful software:-)

9 – A smile, that means a link to Vmware Player with a 4.7gb (wow!fit on a dvd-r, a dream for a good backup) virtual winxp machine very well configured for everything that need it (for example the Lotus Domino Administrator…)

10 – Gimp or similiar photo/graphic editor

11 – K3b (burn cd/dvd)

12 – Serpentine (burn audio cds better than its brothers)

13 – Power off…
