Mail::Sender

Mail::Sender teegi abil on Perlis hea kirju saata, Debianis

 bash# apt-get install libmail-sender-perl

ja skript

 #!/usr/bin/perl
 use Mail::Sender;
 
 $sender = new Mail::Sender
 {smtp => 'smtp.loomaaed.tartu.ee', from => 'mart@loomaaed.tartu.ee'};
 
 $sender->MailMsg({to => 'priit@loomaaed.tartu.ee',
          subject => 'Test 12',
          msg => "Teksti sisu"
          });

linux + gprs + irda

Riistvaraks on Sony Ericsson K550 ning IBM T42 ning operatsioonisüsteemiks Debian Lenny standardse testingu tuumaga. Eesmärgiks on seada käima arvuti internetiühendus üle irda (FIR) telefoniga ning kasutades gprs'i.

Esialgu on tegu nö käelise juhendiga, lähtepunktina ei tohiks olla irdasse puutuvaid mooduleid laaditud

 emmija:~# lsmod | grep ir
 dm_mirror              20928  0 
 dm_mod                 52160  2 dm_snapshot,dm_mirror
 firmware_class          9504  1 pcmcia

Failis /etc/modprobe.d/irda-utils peab olema kirjas

 alias irda0 nsc-ircc
 options nsc-ircc dongle_id=0x09 io=0x2f8 irq=3 dma=3
 install nsc-ircc /bin/setserial /dev/ttyS1 uart none port 0 irq 0; /sbin/modprobe --ignore-install nsc-ircc

Serial pordid peaks nö välja lülitatud oleks olema

 emmija:~# setserial /dev/ttyS0
 /dev/ttyS0, UART: unknown, Port: 0x0000, IRQ: 0
 emmija:~# setserial /dev/ttyS1
 /dev/ttyS1, UART: unknown, Port: 0x0000, IRQ: 0

Kui pole, öelda

 bash# setserial /dev/ttyS0 uart none

Ühtegi irattach'i ei tohiks ka olla

 emmija:~# ps aux | grep ir
 root         4  0.0  0.0      0     0 ?        SN   08:36   0:00 [ksoftirqd/0]
 root      2973  0.0  0.0   1784   568 pts/0    S+   09:01   0:00 grep ir

Selleks, et telefon ja arvuti üle irda suhtlema hakkaks, tuleb laadida vajalikud moodulid sobivate parameetritega

 emmija:~# modprobe nsc_ircc

Syslog ütleb selle peale

Tekivad ka /dev/ircomm* seadmed.

Kui seejärel öelda

 bash# irdadump

ning asetada sisselülitatud irdaga telefon arvuti lähedale, siis on paista selline tulemus

Kusjuures ilma telefonita on ainult emmija paista.

Seadme mõned olulised irda toimetamist mõjutavad nn sysctl parameetrid

 emmija:~# cat /proc/sys/net/irda/max_baud_rate 
 16000000
 emmija:~# echo 115200 > /proc/sys/net/irda/max_baud_rate 
 emmija:~/irda# cat /proc/sys/net/irda/max_tx_window 
 7
 emmija:~/irda# echo 1 > /proc/sys/net/irda/max_tx_window 
 emmija:~/irda# cat /proc/sys/net/irda/max_tx_data_size 
 2042
 emmija:~/irda# echo 2000 > /proc/sys/net/irda/max_tx_data_size

Nüüd peaks olema arvuti ja telefoni vahel irda seadistatud ning telefon olema kasutatav modemina, nt cu programmiga pöördudes

 emmija:~/irda# chmod o+rw /dev/ircomm0 
 emmija:~/irda# /usr/bin/cu -l /dev/ircomm0 -s 115200
