Ubuntu 20 has changed location of iptables binaries

Post by datalude »

Just installed on a new Ubuntu 20 desktop. It turns out that Ubuntu has the iptables binaries in /usr/sbin/ now instead of /sbin/ .

On installing csf with the install.sh script, it failed to pick this up and the iptables locations in the csf.conf file were left as /sbin/

When these were changed manually the perl test script still fails to locate iptables.

Code: Select all

   sudo 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.
In the end I just put in symlinks and that seems to be OK now.

Code: Select all

sudo ls -hal /sbin/ip*table*
lrwxrwxrwx 1 root root  19 Nov  5  2019 /sbin/ip6tables -> /usr/sbin/ip6tables
lrwxrwxrwx 1 root root  27 Nov  5  2019 /sbin/ip6tables-restore -> /usr/sbin/ip6tables-restore
lrwxrwxrwx 1 root root  24 Nov  5  2019 /sbin/ip6tables-save -> /usr/sbin/ip6tables-save
lrwxrwxrwx 1 root root  18 Nov  5  2019 /sbin/iptables -> /usr/sbin/iptables
lrwxrwxrwx 1 root root  26 Nov  5  2019 /sbin/iptables-restore -> /usr/sbin/iptables-restore
lrwxrwxrwx 1 root root  23 Nov  5  2019 /sbin/iptables-save -> /usr/sbin/iptables-save
