SSH and Embedded Devices Yet Again
After updating the office desktop to Slackware 15.0, attempting to SSH into the house network router failed. The problem was believed to have been resolved during previous testing with 15.0. Not really.
In addition to adding
HostkeyAlgorithms +ssh-rsa to the user’s SSH config file, apparently the option
PubkeyAcceptedKeyTypes +ssh-rsa also is needed. Except in previous testing that option was not required.
During those previous testing days OpenSSH 8.8p1 was installed. Since then OpenSSH has been updated. The current version in Slackware 15.0 is 9.3p1.
Newer is not always better.
Problem solved but Yet Another Example why updating computers is so frustrating.
Something always breaks. Always.
