Cannot connect to USGS Landsat servers from IPT machines running Linux?


If you are experiencing troubles in getting Landsat products through USGS the possible reason can be the MTU size.

By defalt CloudFerro VMs have MTU set to 8950 to maximize the network performance.

However in case of getting Landsat products the MTU has to be lowered to 1500 or less.

In CentOS please do the following:

$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0

add the following lines:

MTU="1500"
IPV6_MTU="1500"

Now save the file (<Esc>:w!q)
and restart the service:

$ sudo service network restart

You can check the MTU with

$ ifconfig
