Problems connecting via ssh.## + +If an attempt at ssh to a host has been denied, (although previously successful), +you may get the following error: + +`ssh_exchange_identification: read: Connection reset by peer` + +This can be caused by an number of reasons. You can first try to delete the line containg the +host from your ~/.ssh/known_host file. If this doesn't work then your ip address may be blocked +and could be listed in the /etc/hosts.deny file. + +To better diagnose the situation try connecting via ssh with the verbose option (-v or -vv) +as this may provide some clues. A message that the connection has been reset by the peer could be +further indication that the ip address is in the host.deny file. +Therefore check the file /etc/hosts.deny for the ip address. If the ip address is listed, +the following steps should then be followed: + + 1. Stop the DenyHosts service: + + `$ systemctl stop denyhosts` + + 2. Remove the ip address from the following files: + + 1. `/etc/hosts.deny` + 2. `/var/lib/denyhosts/hosts` + 3. `/var/lib/denyhosts/hosts-restricted` + 4. `/var/lib/denyhosts/hosts-root` + 5. `/var/lib/denyhosts/hosts-valid` + 6. `/var/lib/denyhosts/users-hosts` + + 3.
