I would like to add these lines to a file at the end sysctl.conf net.ipv6.conf.all.disable\_ipv6=1 net.ipv4.tcp\_no\_metrics\_save = 1 net.ipv4.tcp\_moderate\_rcvbuf = 1 net.ipv4.tcp\_fin\_timeout = 15 net.ipv4.tcp\_keepalive\_time = 1800 net.ipv4.tcp\_keepalive\_probes = 4 I am adding these using several lineinfile: What is the best way to knock it down with one module ---

Hi there, I agree it’s the best to use a specific module (sysctl\_module) for your specific task, but here’s the alternative I made: [https://galaxy.ansible.com/list#/roles/1475](https://galaxy.ansible.com/list#/roles/1475) (the table rendering is broken, see [https://github.com/yaegashi/ansible-role-blockinfile](https://github.com/yaegashi/ansible-role-blockinfile) instead) ` - hosts: all sudo: yes roles: - yaegashi.blockinfile tasks: - name: Update sysctl.conf blockinfile: | dest=/etc/sysctl.conf backup=yes content=‘net.ipv6.conf.all.disable\_ipv6=1 net.ipv4.tcp\_no\_metrics\_save = 1 net.ipv4.tcp\_moderate\_rcvbuf = 1 net.ipv4.tcp\_fin\_timeout = 15 net.ipv4.tcp\_keepalive\_time = 1800 net.ipv4.tcp\_keepalive\_probes = 4’ notify: Reload sysctl handlers: - name: Reload sysctl.conf shell: sysctl -p ` 2014年8月29日金曜日 3時25分15秒 UTC+9 David Karban: > Hí Darup, > > i believe that Brian thougth sysctl module: [http://docs.ansible.com/sysctl\_module.html](http://docs.ansible.com/sysctl_module.html) > > > I am currently doing this, want a better one 🙂 > > > > - name: Changes to sysctl.conf > > lineinfile: > > dest=/tmp/1 > > regexp=“{{ item.regexp }}” > > line=“{{ item.line }}” > > with\_items: > > > > - { regexp: ‘^net.ipv6.conf.all.disable\_ipv6’, line: ‘net.ipv6.conf.all.disable\_ipv6 = 1’ } > > > > - { regexp: ‘^net.ipv4.tcp\_no\_metrics\_save’, line: ‘net.ipv4.tcp\_no\_metrics\_save = 1’ } > > > > - { regexp: ‘^net.ipv4.tcp\_moderate\_rcvbuf’, line: ‘net.ipv4.tcp\_moderate\_rcvbuf = 1’ } > > > > - { regexp: ‘^net.ipv4.tcp\_fin\_timeout’, line: ‘net.ipv4.tcp\_fin\_timeout = 15’ } > > > > - { regexp: ‘^net.ipv4.tcp\_keepalive\_time’, line: ‘net.ipv4.tcp\_keepalive\_time = 1800’ } > > > > - { regexp: ‘^net.ipv4.tcp\_keepalive\_probes’, line: ‘net.ipv4.tcp\_keepalive\_probes = 4’ } > > > > – > > You received this message because you are subscribed to the Google Groups “Ansible Project” group. > > To unsubscribe from this group and stop receiving emails from it, send an email to [ansible-proje...@googlegroups.com](mailto:ansible-proje...@googlegroups.com). > > To post to this group, send email to [ansible...@googlegroups.com](mailto:ansible...@googlegroups.com). > > > > To view this discussion on the web visit [https://groups.google.com/d/msgid/ansible-project/53caf444-54d6-4e4f-8031-347d1f7e4430%40googlegroups.com](https://groups.google.com/d/msgid/ansible-project/53caf444-54d6-4e4f-8031-347d1f7e4430%40googlegroups.com?utm_medium=email&utm_source=footer). > > > > For more options, visit [https://groups.google.com/d/optout](https://groups.google.com/d/optout). > > – > > David Karban > Specialista na správu linuxových serverů > [www.karban.eu](http://www.karban.eu) Regards, ---
