Debian Notes

Some notes on customising Debian.

msmtp

This is a outgoing mail application that can be used with mutt to sent email to a remote smtp server, eg riseup.net.

See the Esmtp_Riseup page for detailed notes on how to set up up to use riseup.net for outgoing email.

apt-get install msmtp

Postfix

dpkg -r exim4
apt-get install -y postfix

Then create a new pricate key, using http://cacert.org/ and this shell script: http://wiki.cacert.org/wiki/VhostTaskForce#ShellScript

cd /root
mkdir bin
cd bin
wget http://guillaume.romagny.free.fr/evaldo/csr.sh
chmod 700 csr.sh
cd ~
./bin/csr.sh

Then move the key to /etc/ssl/private/ and the cert to /etc/ssl/certs/

Then edit /etc/postfix/main.cf and change the path to the keys:

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

Install the CAcert root:

cd /etc/ssl/
wget http://www.cacert.org/cacert.crt -O cacert.pem

And add this to /etc/postfix/main.cf:

smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes

smtp_use_tls = yes
smtp_enforce_tls = no
smtp_tls_key_file =/etc/ssl/private/server-name_privatekey.pem
smtp_tls_cert_file =/etc/ssl/certs/server-name_server.pem
smtp_tls_CAfile =/etc/ssl/cacert.pem
smtp_tls_loglevel = 1

Then install postgrey and add the following to /etc/postfix/main.cf:

# postgrey
smtpd_recipient_restrictions =
  reject_non_fqdn_sender,
  reject_non_fqdn_recipient,
  permit_mynetworks,
  reject_unknown_sender_domain,
  reject_unauth_destination,
  reject_rbl_client  sbl-xbl.spamhaus.org,
  reject_rbl_client  cbl.abuseat.org,
  reject_rbl_client  smtp.dnsbl.sorbs.net,
  check_policy_service inet:127.0.0.1:60000
  permit

DNS

dbndns is a Debian fork of djbdns:

apt-get install dnscache-run dnscache-run

UXterm

To make UXterm start with a large font size edit /etc/X11/app-defaults/UXTerm

*VT100.font1:   -misc-fixed-medium-r-normal--8-80-75-75-c-50-iso10646-1
*VT100.font2:   -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso10646-1
*VT100.font3:   -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1
*VT100.font4:   -misc-fixed-medium-r-normal--13-120-75-75-c-80-iso10646-1
*VT100.font5:   -misc-fixed-medium-r-normal--18-120-100-100-c-90-iso10646-1
*VT100.font:    -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1

libpam-ssh

Login with your ssh passphrase.

apt-get install pam-ssh

Then check the instructions in /usr/share/doc/libpam-ssh/README.Debian and edit /etc/pam.d/gdm to:

#%PAM-1.0
auth    requisite       pam_nologin.so
auth    required        pam_env.so readenv=1
auth    required        pam_env.so readenv=1 envfile=/etc/default/locale

USB G3 Dongle

Huawei E1550

See the Huawei E1550 on Debian guide and Three.co.uk and the HUAWEI E1550 on Debian, the second of these seems to be the most promising...

wget http://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.5.tar.bz2
bunzip2 usb_modeswitch-1.0.5.tar.bz2 
tar -xvf usb_modeswitch-1.0.5.tar 
cd usb_modeswitch-1.0.5
gcc -l usb -o usb_modeswitch usb_modeswitch.c
sudo make install
cd /etc
sudo wget http://www.draisberghof.de/usb_modeswitch/usb_modeswitch.conf

Huawei E160

Notes about using a Huawei E160, which costs £5 per month with 1Gb data transfer from Virgin.

Edit /etc/wvdial.conf and change it to:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
Username = ; 
New PPPD = yes
Password = ; 
Phone = *99#
Modem = /dev/ttyUSB0
Baud = 460800

Then start the connection with wvdial and Ctrl-C to end it:

Check the data transfer allowance and the SMS messages on the phone using Gammu, first create ~/.gammurc and add this to it:

[gammu]
port = /dev/ttyUSB0
model =
connection = at19200
synchronizetime = yes
logfile =
logformat = nothing
use_locking =
gammuloc =

Then:

gammu --sendsms TEXT 789789
Enter message text and press ^D:
