Raspberry Pi – Simple Log Watcher ‚Swatch‘ die Echtzeitbenachrichtigung für ‚Snort‘
Mittwoch, September 3rd, 2014 Mit dem Simple Log Watcher ‚Swatch‘ können Sie Logdateien in Echtzeit nach bestimmten Mustern überwachen lassen und entsprechende Aktionen ausführen lassen – dies kann ein Skript sein was ausgeführt werden soll oder wie in unserem Fall eine eMail-Benachrichtigung und dafür legt man unter /root/ eine Datei namens „.swatchrc“ an die uns als Konfigurationsdatei für Swatch dient
# apt-get install swatch
# cd
# touch .swatchrc
# vi .swatchrc
watchfor /Priority\: 1/
echo=normal
mail=josef.schuster@dpsolution.de,subject=[SNORT] Priority 1 Alert
watchfor /ICMP test/
echo=normal
mail=josef.schuster@dpsolution.de,subject=[SNORT] ICMP test
# swatch –daemon -c /root/.swatchrc –input-record-separator=“\n\n“ -t /var/log/snort/alert
Raspberry Pi – ‚Postfix‘ als Mail Relay Agent
Mittwoch, September 3rd, 2014 Um Mails verschicken zu können wird der Mail Transfer Agent ‚Postfix‘ benötigt um einfach Mails an einen bestehenden Mailserver (z.B. 1und1) weiterzuleiten
# apt-get install mailutils
# apt-get install libsasl2 libsasl2-modules sasl2-bin
# apt-get install postfix
# vi /etc/postfix/main.cf
relayhost = smtp.1und1.de:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_use_tls = yes
inet_protocols = ipv4
# vi /etc/postfix/sasl_passwd
smtp.1und1.de josef.schuster@dpsolution.de:<password>
# chmod 600 /etc/postfix/sasl_passwd
# postmap /etc/postfix/sasl_passwd
# /etc/init.d/postfix reload
# mail -s „testbetreff“ josef.schuster@dpsolution.de < testmailtext.txt
