Ookla Server Auto Start After Machine reboot or Network Outage..!

 Here i will show you how you can enable your Ookla server in Auto start mode when there is a machine reboot or any kind of network outage . find the configuration below.

 It is highly advisable to create own systemd services or udev rules to run scripts during boot instead of using this file  /etc/rc.d/rc.local .

make sure you have given executable permission to your own systems script. 

chmod +x /etc/systemd/system/speedtest.service

[root@localhost ~]# vi /etc/systemd/system/speedtest.service
[Unit]
After=network.target
[Service]
User=root
Group=root
WorkingDirectory=/usr/ookla/
Type=simple
KillMode=mixed
ExecStart=/usr/ookla/OoklaServer
TimeoutStartSec=30
TimeoutStopSec=60
Restart=always
[Install]
WantedBy=multi-user.target


[root@localhost ~]#

systemctl enable speedtest.service
 systemctl start speedtest.service
 systemctl status speedtest.service
systemctl daemon-reload

How to Troubleshoot of a website if that website is not opening .

Let's say we will try on google.com. and we are not able to open the google.com website.

Step-1 = Ping to the website which is not opening.

First you have to check the ping to that website. There may be a possibility that ICMP is blocked in the destination end due to security concern...

C:\Users\hp>ping google.com
Pinging google.com [142.250.194.206] with 32 bytes of data:
Reply from 142.250.194.206: bytes=32 time=49ms TTL=58
Reply from 142.250.194.206: bytes=32 time=46ms TTL=58
Reply from 142.250.194.206: bytes=32 time=48ms TTL=58
Reply from 142.250.194.206: bytes=32 time=51ms TTL=58
Ping statistics for 142.250.194.206:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 46ms, Maximum = 51ms, Average = 48ms
C:\Users\hp>

You can see above that ICMP is not blocked in google end and we are getting Ping to google.com.Thats Fine..

Till Now we are getting the ping but 

2-Check Traceroute to google.com to verify whether you can reach the destination or not .

C:\Users\hp>tracert google.com

Tracing route to google.com [142.250.193.206]

over a maximum of 30 hops:

  1     1 ms     1 ms     1 ms  192.168.0.1

  2     2 ms     1 ms     1 ms  103.14.9.18

  3    43 ms    44 ms    42 ms  103.15.9.17

  4    43 ms    43 ms    44 ms  103.6.9.26

  5    46 ms    45 ms    46 ms  72.4.203.200

  6    45 ms    46 ms    45 ms  142.250.244.151

  7    45 ms    45 ms    45 ms  142.250.54.97

  8    47 ms    44 ms    46 ms  del11s17-in-f14.1e100.net [142.250.193.206]

Trace complete.

C:\Users\hp>

As you can see above that the Traceroute is showing OK and we are able to reach the destination.

Step-3=Check the DNS resolve , weather the DNS is proper or not .

C:\Users\hp>nslookup
Default Server:  UnKnown
Address:  192.168.0.1
> google.com
Server:  UnKnown
Address:  192.168.0.1
Non-authoritative answer:
Name:    google.com
Addresses:  2404:6800:4002:81c::200e
          142.250.194.206
>

As you can see above that DNS is working properly and we are able to resolve from name to IP and IP to name.

Step-4= Check the Telnet to Website whether the https://google.com is open on 443 port or not.

To check in Telenet , Got to your cmd and write the telnet google.com 443

C:\Users\hp>telnet google.com 443

You can see above that we are able to access the website on 443 port , it means everything is fine .

Summary.

Till now everything is fine from our end but still we are not able to access the website . So now you have to contact your ISP for checking this issue because this issue can be with your public IP or in ISP end there is some routing issue such as Assymetric routing or Routing failure in the transit etc etc..and also there is a possibility that somewhere in transit  Your public IP address is blocked.

Cisco Bandwidth Rate link on Catalyst series(3550,3750,3560,2960)

 There is a 2 way to configure the QOS bandwidth SHaping on port in CIsco L2/L3 switches.

1-SRR(Only Download traffic can be controlled )
2-Service Policy.(Only one direction you can control).

if you want to be both then you can configure the both SRR and Service policy on same port .

SRR

srr-queue bandwidth limit %

You have to set the bandwidth as a percentage of the link speed. The options are 10-99 percent. This means that if you want a limit less than 10Mb you must set the port’s physical speed to 10 and the duplex to full. You will then have to statically configure the client to 10/full. This, however, only limits the egress traffic.

int 0 /12
srr-queue bandwidth limit 10

Service Policy

We use this to match and limit our ingress traffic.

First, you must enable mls qos on your switch, otherwise your matching won’t work.

Make Sure you have enabled the mls qos command .

mls qos

1-Next we define our class map. We have it set to match ip traffic with DSCP set to 0.

class-map match-all rate-limit
  description Bandwidth Control
 match ip dscp default

2-We then create policy maps that have our desired speeds:

policy-map 8meg

 class rate-limit

  police 8192000 192000 exceed-action drop

3-Last we apply this to the interface:

int fa0/1

service-policy input 8meg
