If you can post a walk-through here that's 90% complete I can look at how I can integrate that with ViciBox.

Mostly I'd be using it to catch SIP scanners and try to feed that back into voipbl.org so that all of vicibox becomes one large crowd-sourced SIP blacklist generator.

That's my true ulterior motive. :)

OK here it goes, its pretty much the same as the 8 install with a few minor changes.

zypper in fail2ban


nano /etc/fail2ban/jail.local


Code: Select all
[DEFAULT]
ignoreip = 127.0.0.1
bantime  = 6048000
findtime  = 600
maxretry = 5
backend = systemd

[asterisk-iptables]
enabled  = true
filter   = asterisk
action   = iptables-allports[name=SIP, protocol=all]
           sendmail[name=VICIBOX-ASTERISK-DETECTOR, dest=yourmail, sender=yourmail]
logpath  = /var/log/asterisk/messages
maxretry = 3
bantime = 6048000

[ssh-iptables]
enabled  = true
filter   = sshd
action   = iptables[name=SSH, port=ssh, protocol=tcp]
           sendmail[name=VICIBOX-SSH-DETECTOR, dest=yourmail, sender=yourmail]

filter   = apache-auth
action   = iptables-allports[name=apache-auth, port=http, protocol=tcp]
           sendmail[name=VICIBOX-APACHE-DETECTOR, dest=yourmail, sender=yourmail]
logpath  = /var/log/apache2/error_log
maxretry = 3

[apache-badbots]
enabled  = true
filter   = apache-badbots
action   = iptables-multiport[name=BadBots, port="http,https"]
           sendmail[name=VICIBOX-BadBots-DETECTOR, dest=yourmail, sender=yourmail]
logpath  = /var/log/apache2/error_log
bantime  = 6048000
maxretry = 1

[pam-generic]
mode = normal
filter = pam-generic
action   = iptables-allports[name=pam-generic]
           sendmail[name=VICIBOX-PAM-DETECTOR, dest=yourmail, sender=yourmail]
bantime  = 6048000
maxretry = 5
enabled = true

[phpmyadmin-syslog]
mode = normal
filter = phpmyadmin-syslog
action   = iptables-allports[name=phpmyadmin-syslog, port=https, protocol=tcp]
           sendmail[name=VICIBOX-PHPMYADMIN-DETECTOR, dest=yourmail, sender=yourmail]

# Jail for more extended banning of persistent abusers
# !!! WARNING !!!
#   Make sure that your loglevel specified in fail2ban.conf/.local
#   is not at DEBUG level -- which might then cause fail2ban to fall into
#   an infinite loop constantly feeding itself with non-informative lines
[recidive]
enabled  = true
filter   = recidive
logpath  = /var/log/fail2ban.log*
action   = iptables-allports[name=recidive, protocol=all]
           sendmail[name=VICIBOX-BADBOY-DETECTOR, dest=yourmail, sender=yourmail]
bantime  = 6048000  ; 10 weeks
#findtime = 60480000   ; 5 hours
findtime = 43200   ; 12 hours
maxretry = 5


systemctl enable fail2ban


systemctl start fail2ban


fail2ban-client status


Advice: add your own ip as ignoreip to avoid risk getting banned from your own server
ignoreip = 127.0.0.1
ignoreip = yourserverip
ignoreip = yourofficeip




Let me know if it works.

you would have to turn whitelist off for that right? not a bad idea though. Maybe setup a honeypot just for that....

here is a failed list of ssh and pam failed tries.... https://www.cyburity.tk/d0wnl0ads/ssh-iptables.txt - theres like 1900 here in just a couple days

Any chance you could share your asterisk.conf and logger.conf. I find working with regex frustrating to say the least.

Thanks either way

actually i wouldnt use fail2ban with vicidial, it ends up bogging down the system after a few months and eventually puts it to a crawl, go with the dynamic portal method, you can follow either of my articles from my blog to do it. If you are using centos, alma or rocky linux, you can follow this article:

Https://dialer.one/how-to-scratch-insta ... ky-centos/

If you are using leap 15.* or Vicibox then you can follow this article:

https://dialer.one/how-to-use-the-built ... r-vicibox/

Or you can also check out this one overall:

Goodluck and I hope this helps

Know where I can find documentation around the dynamic portal app? I have checked both the agent and manager manuals and nothing.

So is dyna portal only whitelisting for agents using vici embedded webtrc phone? So agent logs into dyna portal, then login to agent console? How does it apply to a sip soft/hard phone behind dynamic IP addresses? It seems the agent will find period where they are unable to connect (internet ip changes), so they will need to relogin to dyna portal to update/whitelist new IP? How does it apply to carriers or maybe that'll be a manual entry in IP tables? I like the idea of dyna portal, since the bad traffic doesn't make it to the sip stack and protects system resource, unlike fail2ban, but just wondering if it will be a one size fill all solution.

yea itll work for sip phones as well, although anytime someone's IP changes, they would need to re-login to the dynamic portal to have there new IP added to the firewall. That goes for sip/hard and web phones. You can add carrier IP's to the ViciWhite list as well as any static IP's for managers or agents because the dynamic portal is set to clear allowed IP's every 14 days by default although this can be changed as needed. Check out these article's below to help you get started with the dynportal:
