Ketika belajar SolarisOS, salah satu tool yang tersedia di SolarisOS untuk memanage servernya adalah Solaris Management Console (SMC). Tool ini berbasis GUI, sehingga jika ingin mengaksesnya, kita perlu menyalakan GUI atau meng-export display ke Xserver external yang kita punya. (more…)
The effect of SSD on Virtual Machine performance. Well, today, we have something unusual compared to our previous SysAdmin classes. it is because we now use SSD in our hypervisor. During the training, the hypervisor is used to host virtual machines according to the scenarios. sometimes we need to install more than 10VMs at the same time which takes ages in the previous storage. In this test, we install solaris OS on proxmox hypervisor. For your information, Installing Solaris 10 on proxmox hypervisor, is a little bit tricky as you need to carefully select hardware for the Operating System. Wrong selection of hardware, can lead to incompatibility and result to kernel panic :-(. Therefore, some of the hardware doesnt support hardware-assisted virtualisation (intel-vt / AMD-V) which result to slower performance.…
[caption id="attachment_5008" align="alignleft" width="150"] VRRP on Mikrotik[/caption] In this webinar, we discuss a mikrotik feature that is called VRRP (Virtual Router Redundancy Protocol ) which could provide dedundancy on the your network. We started the webinar by introducing the VRRP protocol, then discuss an example implementation on Mikrotik Router. some mistakes on VRRP configuration were also covered here. (more…)
In this webinar, we discuss a feature from mikrotik routerOS that is called fasttrack. This feature will improve routerboard performancce for particular connection. unlike fastpath, using fasttrack requires trigger from firewall filter/mangle. Correct understanding of connection and connection-tracking is very crucial when configuring the trigger. (more…)
In this webinar, we discuss a feature from mikrotik routerOS that is called fastpath. This feature will improve routerboard performance by increasing number of packet per second and lowering CPU usage. Fastpath requires several conditions to be active, and the webinar is talking about them. Presentation slides are available on slideshare : Mikrotik fastpath from Achmad Mardiansyah And recording is available on youtube:
In this webinar, we discuss a feature from mikrotik routerOS that is called hotspot. This feature enables administrator to provide web-based authentication for clients. Hotspot login page can be modified to customer need. walled-garden allows clients to access website without authentication, and radius feature enable hotspot to query external radius server for account. Presentation slides are available on slideshare : Mikrotik hotspot from Achmad Mardiansyah And recording is available on youtube:
In this webinar, we started the discussion with a review of wireless fundamental, understanding several concept that engineer need to know. We discuss brief about ubiquiti itself, and their airmax products. and and the end of presentation we talk about parameters on ubiquiti airmax web configuration. Presentation slides are available on slideshare : Learning wireless with ubiquiti airmax from Achmad Mardiansyah And recording is available on youtube:
In this webinar, we started refreshing our understanding about mikrotik firewall, how it works, and how its executed on packet flow. We continue with a discussion about Layer7 protocol, how l7 works, how it replaces p2p protocol, l7 capabilities, and an example of how l7 is implemented. Presentation slides are available on slideshare: Layer7 firewall on mikrotik from Achmad Mardiansyah And recording is available on youtube:
This topic was presented at Mikrotik user Meeting (MUM), Laos, May 8, 2017. The primary focus on this presentation is the Quickset feature which can save lots of time to configure their RouterOS. Presentation slides are available on slideshare: Jumpstart your router with mikrotik quickset from Achmad Mardiansyah And recording is available on youtube:
In this webinar, we were discussing about Network Address Translation (NAT), how NAT was born, NAT drawbacks, and how get rid of it. there are some examples of how we setup NAT in RouterOS. Presentation slides are available on slideshare: Mikrotik firewall NAT from Achmad Mardiansyah And recording is available on youtube:
