Once you login to a new server the first thing to do especially if it is a server you never logged in is to check basic things as Kernel version with:


root@jeremiah:/home/hipo# uname -a;
Linux jeremiah 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 (2018-08-21) x86_64 GNU/Linux


Check remote server hardware configuration with tools as


# dmidecode
# lshw

root@jeremiah:/home/hipo# lsb_release -a
