link installasi

install menggunakan add/remove program (gui yaourt - pacman), cari istilah yang harus di install dari link dibawah

http://binarynature.blogspot.co.id/2015/11/install-configure-gns3-arch-linux.html

Untuk menambahkan port tap/nat dll (khususnya pada cloud), harus mengubah setting dynamips (karena aslinya hanya bisa diakses oleh user root, sehingga kl tdk diubah harus buka gns3 pake user root)

Agar bisa mengakses port (dynamips) tanpa menggunakan user root:

# cd /usr/sbin #lokasi dynamips
# sudo setcap cap_net_raw,cap_net_admin+eip dynamips

ref:

https://github.com/GNS3/gns3-server/issues/153
http://forum.gns3.net/topic6251.html

connect antara host vs guest os (atau konek winbox-host ke mikrotik-quest):

• gunakan cloud
• setting local/tap net (harus gunakan nio tap)

https://gns3.com/discussions/how-to-connect-to-gns3-qemu-rout
https://mum.mikrotik.com//presentations/TH16/presentation_3597_1473326800.pdf

cara mengaktifkan tap

-- add tap device

sudo ip tuntap add dev tap0 mode tap # mengaktifkan tap dengan nama tap0, bebar bisa jg eth0 dll

-- add ip to tap device

sudo ifconfig tap0 199.0.0.1/24 # memberikan ip 199.0.0.1 netmask 255.255.255.0

share internet

• create ip table

iptables -t nat -A POSTROUTING -o wlo1 -j MASQUERADE
iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i tap0 -o wlo1 -j ACCEPT

sysctl net.ipv4.ip_forward=1
sysctl -a | grep forward

http://www.calculate-linux.org/issues/884   #error /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied

langkah

1. check jenis vga

inxi -G

output

Graphics:  Card-1: Intel HD Graphics 530
           Card-2: NVIDIA GM107M [GeForce GTX 960M]
           Display Server: X.Org 1.19.3 driver: intel Resolution: 1920x1080@60.01hz
           GLX Renderer: Mesa DRI Intel HD Graphics 530 (Skylake GT2) GLX Version: 3.0 Mesa 17.0.1

atau gunakan perintah, untuk memastikan apakah vga jenis optimus atau bukan

lspci -vnn | grep '\''[030[02]\]'

output

00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 530 [8086:191b] (rev 06) (prog-if 00 [VGA controller])
01:00.0 3D controller [0302]: NVIDIA Corporation GM107M [GeForce GTX 960M] [10de:139b] (rev ff) (prog-if ff)

terlihat NVIDIA pada alamat "PCI:01:00:0"

2. install nonfree driver NVIDIA bumblee

sudo mhwd -a pci nonfree 0300 -f

jika ada error

Screen 0 deleted, tambahkan setting secreen 0 pada file /etc/bumblebee/xorg.conf.nvidia
