Hi everybody!

A long time ago in a galaxy far far away ...
I was released a DirectSlave software. Many of forum users helped me a lot to debug and improve DS and bring this software to really corporate production level.

But now, it's time for something new!

So, I proudly introduce you a new DirectSlave/GO (GO - because it's writen in GoLang and setup is easy as 1.. 2.. 3.. GO!):

+ Binary!
+ Rock solid
+ Statically linked
+ Cross-platform
+ TLS 1.2 and HTTP/2 onboard
+ /CMD_EMAIL_POP support
+ Less memory footprint (can be used on tiny virtual instances with < 512Mb RAM)
+ Less CPU usage
+ A lot of improvements in speed
+ No more dependencies / perl modules
+ Setup is easy as 1.. 2.. 3.. GO!
+ Available for Linux i386/x32_64/arm & FreeBSD i386/amd64 (all in single archive distribution).

Download it here -- https://regme.in/download/directslave-3.0.2-beta-all.tar.gz

First time installing: see README
Updating from 2.x: see UPDATING

Also, feel free to contact me.

Have a nice expirience with brand new DirectSlave/GO!

1.. 2.. 3.. GO!

I am not sure if this will help, but I added allow-transfer and allow-notify in /etc/bind/named.conf.options (directadmin server) and pointed to the IP address of the slave.

allow-transfer { 1.2.3.4; };
allow-notify { 1.2.3.4; };
notify yes;

Is your named-workdir /etc/named/secondary ? Make sure bind/named has access to directory /etc/named/secondary/.

I update DA config and re-check the bind permission OK, but still no .db zone file in named-workdir.

I did:
yum install bind
firewall-cmd --permanent --zone=public --add-port=2222/tcp
firewall-cmd --permanent --zone=public --add-port=53/udp
firewall-cmd --reload
chown -R named:named /usr/local/directslave
chown -R named:named /var/named

I put the slaves in /var/named directory

Code:

named_workdir   /var/named/slaves
named_conf      /var/named/directslave.inc
rndc_path       /usr/sbin/rndc

Change named_workdir (in directslave.conf) to: /var/cache/bind
Restart directslave (and bind9)

See file: /etc/apparmor.d/usr.sbin.named

Code:

  # /etc/bind should be read-only for bind
  # /var/lib/bind is for dynamically updated zone (and journal) files.
  # /var/cache/bind is for slave/stub data, since we're not the origin of it.
  # See /usr/share/doc/bind9/README.Debian.gz
  /etc/bind/* r,
  /var/lib/bind/** rw,
  /var/lib/bind/ rw,
  /var/cache/bind/** lrw,
  /var/cache/bind/ rw,

Hi,

How to make directslave auto start after reboot in Ubuntu ?

Hi,

There are several ways. I have not tested it yet with directslave and already erased the ubuntu test system.

A: crontab
You can use crontab, by adding @reboot /usr/local/directslave --run
1. crontab -e
2. @reboot /usr/local/directslave --run

B: /etc/rc.local
You can edit /etc/rc.local file and add /usr/local/directslave --run

c: Upstart or systemd
I believe Ubuntu 16.04 use systemd, please look at the example script at https://wiki.ubuntu.com/SystemdForUpstartUsers
The location of the new service file should be in /etc/systemd/system or /lib/systemd/system

Finally getting some time to work on implementing this. Quick, lazy question on the slave server, does anybody have any recommendations on a cheap, reliable (cloud) provider in the US that they like? I have an AWS account, but their hosting services seem to get pricey quickly, IIRC. I've worked with a lot of budget, shared hosts over the years, but most don't allow much/any shell access....

Check lowendbox.com, companies post their offers on that website. You can see the user experiences/reviews on each deal.

Thanks DhoTjai, looks like a good resource.

Hello,

I'm trying to install DirectSlave on centos 7.
Everything is working i guess.
Except my *.db files look weird and not like they are on the server with directadmin.

This is how my *.db files right now, this can't be right?

Code:

^@^@^@^B^@^@^@^AY�^U-^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@n^@^A^@^F^@^@^@^@8@^@^@^@^A^@^T^Oaquariummanager^Bnl^@^@D^Cns1^Hhostplus^Bnl^@

I've 3 other domains setup and al look somewhat similar.

Does anybody have this same problem and how did they fix it?
There is also no error or what so ever.
