Bug ID: 2479
Summary: ssh-keyscan non-standard port broken
Product: Portable OpenSSH
Version: 6.9p1
Hardware: amd64
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: ssh-keyscan
Assignee: [email protected]
Reporter: [email protected]
If one passes the -p option for a non-standard port to ssh-keyscan when
using the -f option to pull hosts from a file, it results in a
known_hosts entry that is incorrect:
micah@muck$ cat /tmp/try
199.254.238.47 micah.riseup.net,199.254.238.47
micah@muck$ ssh-keyscan -t rsa -p 4422 -f /tmp/try > /tmp/known
micah@muck$ cat /tmp/known
[micah.riseup.net,199.254.238.47]:4422 ssh-rsa DATA
It seems like putting a list of hostnames,ips inside of the [] doesn't
work:
micah@muck:dotfiles$ ssh -oUserKnownHostsFile=/tmp/known
[email protected] -p 4422
The authenticity of host '[micah.riseup.net]:4422
([199.254.238.47]:4422)' can't be established.
RSA key fingerprint is
SHA256:CbHIxWJjFKJk5V+G09XeiABqIRTooC646ZfSl7FRp2w.
Are you sure you want to continue connecting (yes/no)?
It should be constructed like this:
[micah.riseup.net]:4422,[199.254.238.47]:4422 ssh-rsa DATA
