It is not a diary the most people have rather a *scratch* Emacs buffer. It keeps notes about everything related to Linux, Open Source, UNIX, MacOSX and software engineering.

It is deprecated (I think so)

I think this blog is deprecated. Honestly it was never been active very much. Google Notes looks very lucrative to these kind of activities and using blog for interesting notes does not work very well, at least for me.

I am using more Twitter and Live Journal look more attractive mostly because of number of people on those services. I am mostly reading with rare posts on Twitter but wish to use Lice Journal more ...

How to disable X/DT login on legacy Solaris8

DT login manager is an annoying program runs by default on Solaris8 boot. Many legacy SPARC computers are connected to non-Sun monitors these days, so it makes very difficult sometimes to run graphical login window and login from the main console. Legacy text login still works indeed.

It is not obvious were dtlogin starts at boot time. inittab does have any entries to run any login managers. rc3.d/ does not have anything useful and rc5.d may be missing. Here the magic command to disable and stop DT login manager:

/usr/dt/bin/dtconfig -d remove DT login manager from boot sequence;

/usr/dt/bin/dtconfig -kill kills existing instance of DT login manager.

sound on Linux, again ...

Honestly I thought the sound problem on Linux is over in Hardy Heron with PulseAudio support. I was wrong ... Flash 9 may not play via PulseAudio and Rthymbox stops working after visiting YouTube in Firefox. Googling on PulseAudio server and UbuntuForums makes it clear an additional library must be installed to make Flash 9 plays nice with PulseAudio:

libflashsupport must be installed in addition to flashplugin-nonfree!

I suspect it would remain like that in 8.10 release. It would be nice if libflashplugin-nonfree had a dependency to libflashsupport so it would be transparent to the user like myself.

The promised (and beta 2) version of Flash 10 is available but it would take time before it would make its way to 8.10.

tcpdump usage is not strait sometimes

tcpdump is a nice CLI utility to log everything from available network interfaces. The only pitfall is by default it truncates all strings to 96 bytes. Here is a cut&paste line:

sudo tcpdump -s256 -Xi lo ...
sudo tcpdump -s256 -Xi lo dst port ...

-X is hex/ASCII form of presentation. 256 is a length of strings to print. lo interface name, eth0, eth1 ...
