Bug ID: 2214
Summary: Key is detected as existing if LogLevel=QUIET
Product: Portable OpenSSH
Version: 6.2p1
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: ssh-copy-id

Add -o LogLevel=INFO to ssh invokation
Current ssh-copy-id script assumes that key is valid if the temporary
log file doesn't contain the string 'Permission denied'. There are
cases when this doesn't occur. One of the cases is when configuration
file contains a LogLevel=QUIET option.
Lets assume that ~/.ssh/config contains:
> Host 127.*
> LogLevel QUIET
And we have no valid key for localhost. Attempting to connect doesn't
give any errors:
> $ ssh -o PreferredAuthentications=publickey -o IdentitiesOnly=yes
> [email protected]
> $ ssh -o LogLevel=INFO -o PreferredAuthentications=publickey -o
> IdentitiesOnly=yes [email protected]
> Permission denied (publickey,password).
The fix is to add LogLevel=INFO to the ssh command, which is a sane
default since ssh-copy-id actually depends on ssh to have loglevel set
to INFO.
