DirectAdmin Knowledge Base and Support

DirectAdmin is a web panel for a simple administration of both virtual and dedicated servers. DirectAdmin is faster, safe and more powerful than any other CP. And we know how to customize and support it.

DirectAdmin script startips fails with an error c: command not found

| 15:38:59 09.12.2021

There is a typo in /usr/local/directadmin/scripts/startips which breaks the script:

The script defines:

DIRECTADMIN_BIN=/usr/local/directadmin/directadmin

but uses:

ADDIP=`${DABIN} c | grep -m1 '^addip=' | cut -d= -f2`

Which results in errors:

./startips: line 36: c: command not found
./startips: line 62: 2a01:7c8:xxx:xx:xx:xx:0:1: command not found
./startips: line 62: 37.xxx.xxx.115: command not found

and missing IPs on a network interface.

As a consequence NGINX might fail to start, dropping an error: 

bind() to [2a01:7c8:xxx:xx:xx:xx:0:1]:80 failed (99: Cannot assign requested address)

It is a patch for /usr/local/directadmin/scripts/startips as a temporary solution, until DirectAdmin developers fix it on their side.

As an additional solution you might set:

net.ipv4.ip_nonlocal_bind = 1
net.ipv6.ip_nonlocal_bind = 1

with the sysctl tool.

Regards.
