Bruscolini.

Gli ultimi due piccoli negretti indiani nani, dotto e pisolo, accesi dalla fine del 2000, sono stati spenti oggi. Erano delle Debian Potato.

Comunque, chissà. Un giorno potrebbero tornare…

(che battuta)

È piacevole svegliarsi e scoprire che durante la notte qualcosa di sbagliato è successo nella propria centrale telefonica e, anziché una ADSL NGI, all’altro capo del filo risponde una ADSL Wind, con tanto di IP di Wind e pagina di “Registrazione della tua nuova Libero ADSL!” (unica pagina accessibile con quella connessione).

Non resta che aspettare che l’idraulico rimetta a posto i tubi.

Mi è arrivata una mail (un call for paper su roba che non ho idea di cosa sia ma se vi interessa sarà a maggio a Marrakech). Negli header si legge:

To: undisclosed-recipients: ;

Vale a dire una mail mandata in Bcc (o Ccn per chi apprezza le traduzioni) a tutti i destinatari che, a rigore, dovrebbero restare nascosti. Andando avanti negli header, però, sorpresa:


X-MailScanner-Dest: a...@....ac.uk, a...@...lip6.fr,
    a...@....ac.uk, a...@....org.uk, a...@....mpg.de,
    [...]
    v…@….cnr.it, w…@….psu.edu, y…@….vt.edu,
    z…@….itc.it


per un totale di 191 indirizzi in chiaro (la censura è mia). Ovvero, tutti i destinatari originali e, nelle intenzioni del mittente, nascosti.

Evviva la privacy! Evviva gli antispam!

“chan-mobile is an Asterisk channel driver that allows you to use bluetooth devices as FXO or FXS channels.”

chan_mobile.c is available in the Asterisk SVN repository and only works with the development version of the PBX software. On the project website there’s a patch that should make this channel work with 1.4.x stable releases of Asterisk but it’s not updated an it doesn’t work anymore.

I wanted to use chan_mobile with the Debian sid package (current version: 1.4.13) so I updated the patch and made it available on my web site:

• patched version of chan_mobile.c
• diff to be applied to the current (r493) svn revision

Hope it helps.

The Linksys SRW208 is an affordable 8-port Fast Ethernet switch with VLAN and QoS support.

It’s been designed for use in small businesses or home environments and the typical user doesn’t need to be a networking expert. In fact, the website says: “Simplified, web based user management for more intelligent networking“, i.e. “the web interface won’t let you do lots of useful but complicated things.” In addition, Internet Explorer seems to be a requirement as some IE-specific JavaScript library functions are used by the configuration interface.

A console menu-based interface is also available (via ssh with a 512-bit key), but with fewer options than the web-based one (e.g. you can’t define VLANs). How to improve this situation? Just follow these steps:

1. Make a ssh connection to the switch.
2. Authenticate yourself.
3. Press Ctrl-Z
4. Type lcli at the prompt, then press Enter.

Et voilà! You now have access to a full-featured Cisco-like CLI, with many more features than the limited set you’re offered by the web and official interfaces.

This seems to be a “bug” in the menu-based interface, so it may well be possible that future revisions won’t allow the user to escape from it.

Thanks to Renzo for this useful trick.
