Testing network
Posted: Sat Feb 10, 2024 1:43 am
Hello,
I'm trying to test how network work.
I use Debian 11 with QEMU. I see an interesting code here: https://github.com/pandax381/xv6-net
It's OK to compile and starting. But nothing work with TCP.
This is what I have on this computer:
In another hand if you have a good tutorial/code that's work with Debian/QEMU?

This is what I have on this computer:
I see on QEMU documentation that the default IP is 10.0.2.2 so I try this with XV6:ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

fedb:971c/64 scope global dynamic mngtmpaddr noprefixroute And on a another console this:ifconfig net1 10.0.2.2 netmask 255.255.255.0
ifconfig net1 up
tcpechoserver&
Nothing append. I try another IP it's equal. Can you help me with this?echo "Hello TCP" > /dev/tcp/10.0.2.2/10007
In another hand if you have a good tutorial/code that's work with Debian/QEMU?
