9 Weeks Pregnant Cervix Still Very Low

Login grafico via ssh


Le risorse di ssh sono infinite!



La cosa più semplice che ssh permette di fare è l'accesso ad una macchina remota e l'impartire comandi da CLI come se si fosse fisicamente di fronte ad essa.



Alcune volte, però, mi sarebbe stato più utile avere un accesso di tipo grafico su quella macchina.



I searched google and found information with XDMCP, a protocol that is already available in Ubuntu's GDM and of course ... (But also other Unix)

This, however, is a protocol that encrypts the traffic and consequence of a solution is not very safe to use on the Internet!

After exhausting research, I found a solution that makes efficient use of ssh to encrypt the data and an X server like Xnest or Xephyr.

Then, on the target machine must be installed in addition to the OpenSSH server Xephyr server (or Xnest).

Then, to get a graphical login on that machine just log in via ssh enabling X11 forwarding with: $ ssh-X remote-host

 
and then run:
 $ xinit / etc/X11/xinit/xinitrc - / usr / bin / Xephyr: 1-
800x600 screen which will open a window on the host by which we are connected inside the graphic session ... And then you can use the target machine with a GUI as if you were in front of it!

In my case, you start a GNOME session that keeps all your settings and preferences saved on the remote machine.

Here is a picture that gives an idea of \u200b\u200bhow things work ...

Masterbation In Restroom

Ubuntu 7.04 fantastica!

I was molto colpito dall'ultima versione di Ubuntu 7.04: Feisty Fawn!



Devo dire che è l'ennesimo grandissimo balzo in avanti in campo informatico effettuato dalla comunità del Software Libero!



L'installazione è fantastica, la gestione dell'hardware meravigliosa, la semplicità d'uso spettacolare e la possibilità di personalizzazione celestiale.



Dopo aver installato il sistema, al riavvio funziona tutto bene.



La cosa che mi piace tantissimo di Ubuntu è che dopo che l'installazione è terminata, al riavvio della macchina essa è già pronta all'uso per un buon numero di casi tipici (tra cui i miei)!

In pratica non mi fa perdere additional time with the action of boring having to reinstall all the programs I need (such as Debian or the award-winning Windows). Then, not making me
annoys me to find several gigabytes of software that does not use! (Such as Suse or Fedora)
These choices were made by the Ubuntu team have made it my operating system "standard."

Then, for those who desire and time to refine the configurations can do so (even though it was edited it all in detail, and then just a few clicks to disable only the services that are not needed).

Now a question springs to mind ... Why people spend a lot of money on Windows Vista or aggiornare Mac OS piuttosto che usare un sistema operativo decente basato su Linux come Ubuntu (e fare una donazione di qualche decina di €)?

How To Clean Flame Sensor

FON: vai avanti così!


Mi sono dovuto ricredere. Le lamentele del vecchio post sono diventate in parte obsolete da quando FON ha cambiato la politica di gestione degli account.



Ora, chi non condivide l'ADSL per un periodo di tempo stabilito (30 giorni), viene classificato come utente che non "mantiene la promessa fatta" e come conseguenza gli viene disattivato l'account.



Questa mi sembra un'ottima trovata per evitare che la gente se ne approfitti dell'ADSL degli altri.



Secondo me, comunque, account management should be further enhanced. For example, 30 days seems to me too .... Better a week! Or maybe use an algorithm that takes into account the earlier days of sharing, so if one goes on vacation and shared throughout the year, he is given a much longer period of time ....

also remain of the view that traffic should be logged, that FON needs to pass the traffic from its proxy that filters some sites and that every user must provide personal documents relevant to the intrinsic safety of the project.

conclude, I am very happy with the new Fonero Gets Fonero policy with which, now, a Fonero may be at a price of Sussudio to the Fonera his friend outside the community.

The idea of \u200b\u200bthe first, in which the fonera was "entirely donated," she was beautiful, but you know, there are the usual sharpers that if they always take advantage ... I should thank them for that change.

On some sites I've seen people with 5 or 6 Fonera on which were the "experiments". My disdain goes to them because they have taken away to people who could keep his word! (At least they could do in order to take 3 or 4 to share the ADSL and pick 1 or 2 to "play"!)

PS I have 3 calls for "Fonero Gets Fonero". If anyone is interested in having the Fonera for € 20, including shipping, can contact me by email.
