I have the following topology
, where there are 4 Cisco Routers deployed in each AWS VPC. I am able to ping and generate traffic from Endpoint1:172.0.1.11 to Endpoint2:172.2.1.10 where the traffic passes through a set of paths called Segment Routing which I have defined in the router R1 e.g.,
(Endpoint1, R1, R2, R3, R2, R1, R2, R3, Endpoint2)
I have got apache installed in both instances, then I put the file that I'd like to download from the client side in the server Endpoint1 and put into a folder /var/www/files/.
Note that, both instances endpoints are in different VPCs.
I aim to send 100Mb file from Endpoint1 to Endpoint2.
In the client instance Endpoint2, I did the following:
curl http://172.0.1.11/files/ubuntu-18.04.2-live-server-amd64.iso
I tried also:
wget http://172.0.1.11/files/ubuntu-18.04.2-live-server-amd64.iso
the logs show:
172.2.1.10 - - [19/Jun/2019:13:20:24 +0000] "GET /files/ubuntu-18.04.2-live-server-amd64.iso HTTP/1.1" 200 295317 "-" "curl/7.58.0"
But both are taking long time, and here what I got from Endpoint2
Connecting to 172.0.1.11:80... connected. HTTP request sent, awaiting response...
this is The iptables of Endpoint1 is the following:
ubuntu@ip-172-0-1-11:~$ sudo iptables -L -n -v Chain INPUT (policy ACCEPT 517 packets, 35198 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 425 packets, 70378 bytes) pkts bytes target prot opt in out source destination
I tried with iperf and it sends the traffic normally.
On the server side:
ubuntu@ip-172-0-1-11:~$ iperf -s -u
and the client:
iperf -c 172.0.1.11 -u -b 20m UDP buffer size: 208 KByte (default) ------------------------------------------------------------ [ 3] local 172.2.1.10 port 38402 connected with 172.0.1.11 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 23.8 MBytes 20.0 Mbits/sec [ 3] Sent 17008 datagrams [ 3] Server Report: [ 3] 0.0-10.0 sec 23.8 MBytes 20.0 Mbits/sec 0.000 ms 20/17008 (0%)
I even tried telnet. It seems that there is a connection between server and client. As well as the client side.
ubuntu@ip-172-2-1-10:~$ telnet 172.0.1.11 80 Trying 172.0.1.11... Connected to 172.0.1.11.
Seems everything is working, except the file is not being downloaded. I tried to implement a python socket and the file from the server to the client has been successfully transmitted. Which means something must be done with the routers.
Does anybody have an idea of how this issue can be solved?
