ClosedCSF anf Firewall Conflict

Hi there,
I was trying to enable CSF. So, I installed CSF and enabled. Then I tried to visit Firewall and now I see a broken page and an error.

Error--------------
*Error* The path to iptables is either not set or incorrect for IPTABLES [/sbin/iptables] in /etc/csf/csf.conf at /usr/local/csf/lib/ConfigServer/URLGet.pm line 26. Compilation failed in require at /usr/local/csf/lib/ConfigServer/DisplayUI.pm line 20. BEGIN failed--compilation aborted at /usr/local/csf/lib/ConfigServer/DisplayUI.pm line 20. Compilation failed in require at /usr/local/csf/bin/cyberpanel.pl line 14. BEGIN failed--compilation aborted at /usr/local/csf/bin/cyberpanel.pl line 14.

How can I fix it?

Welcome @engrrajonahmed Happy New Year

Are you using the latest build + commit ?

Hi, Happy New Year

Yes, it’s a fresh instance and the latest version.

System:
CyberPanel: v2.3.3
OS: Ubuntu 20.04 LTS

Thank you!

Well an upgrade wunt fix anything about the firewall or csf.

We can install csf manually like this

# assume wget and git is installed
$ apt install libnet-libidn-perl libcrypt-ssleay-perl libio-socket-inet6-perl libsocket6-perl libio-socket-ssl-perl perl iptables -y
$ wget http://download.configserver.com/csf.tgz
$ tar -xvfz csf.tgz
$ cd csf
$ bash install.sh || sh install.sh
## test if it works on this server
$ perl /usr/local/csf/bin/csftest.pl

$ nano /etc/csf/csf.conf
> change TESTING = "1" to TESTING = "0"
> change RESTRICT_SYSLOG = "0" to RESTRICT_SYSLOG = "3"

$ systemctl enable --now csf

Go to https://SERVER_URL:8090/firewall/csf and block and unblock whichever ports you need plus any ip addresses

Hi @josephgodwinke bro,
I followed your instruction and got a few errors:

mkdir: cannot create directory ‘/etc/csf’: File exists

When I tried to test it using the command you mentioned I got:
$ root@server:~/csf# perl /usr/local/csf/bin/csftest.pl

Testing ip_tables/iptable_filter...open3: exec of /sbin/iptables -I OUTPUT -p tcp --dport 9999 -j ACCEPT failed: No such file or directory at /usr/local/csf/bin/csftest.pl line 144.

And I am getting the same error on Firewall page:

*Error* The path to iptables is either not set or incorrect for IPTABLES [/sbin/iptables] in /etc/csf/csf.conf at /usr/local/csf/lib/ConfigServer/URLGet.pm line 26.

Any suggestion for me?

I thought you would uninstall configserver completely first then install it the way I sent

$ cd /etc/csf
$ sh uninstall.sh
$ cd ~
## start installing here

I uninstalled it completely. Okay, let me try again…

@josephgodwinke
Thanks for your help. By the way, is it normal that the /firewall page is getting redirected to /configservercsf?

Before installing the CSF I ran the following command:
$ ln -s /usr/sbin/iptables /sbin/iptables

It fixed the issue.

Thank you!

Yes to /firewall if not installed /configservercsf/ if csf is installed. Sorry for this

@josephgodwinke
Yes, that is the CSF settings page(Security > CSF).
But when I try to visit the Firewall page (Security > Firewall) CyberPanel redirects me to ConfigServer Security & Firewall settings page(Security > ConfigServer Services > ConfigServer Security & Firewall).

Why http://Server-IP:8090/firewall is getting redirected to http://Server-IP:8090/configservercsf?

** I know what CSF means.

Thank you!

Yes this is correct firewalld and configserver use case is one and same thing its like having pureftpd and vsftpd. Installing csf replaces firewall url with configserver

@josephgodwinke Thank you, brother! <3
