people here are not thinking in whole systems-- roads have dual purpose.. there is security AND there is trade .. a world without trade is a poor world.. that includes the intellectual arts, civilian institutions cooperating, common issues like Climate.

The voices here that say "I block everyone, don't bother me with your whining" .. it is a security practice.. OK. security is not the whole story of civilizations; obstinate thinking leads to ignorance, not evolution.

The topic is SSH, an administrative and secured access. Yes security applies. to be on-topic
