sshd regression: keyword AuthenticationMethods extra arguments at end of line

[Daniel Jakots]

Hi,

I updated some machines of mine to a newer snapshot and got some
problems with sshd.

Old snapshot is from 2021-05-19.
New snapshot is from 2021-06-05 (today).

I use the default config (only change is LogLevel VERBOSE) and at the
end I put some custom config which I give here:

     90 # Custom config
     91 PermitRootLogin without-password
     92 
     93 # 2FA (yubikey or totp)
     94 PasswordAuthentication yes
     95 AuthenticationMethods publickey,password
     96 #AuthenticationMethods publickey
     97 
     98 AllowUsers www
     99 
    100 
    101 # 1FA for those users
    102 Match User zzz
    103         AuthenticationMethods publickey
    104 Match Address 192.168.111.34/32
    105         AllowUsers xxx
    106         AuthenticationMethods publickey
    107 
    108 # For 2FA but also to allow root from legit IP
    109 Match Address 192.0.2.221
    110         AuthenticationMethods publickey
    111         AllowUsers root www xxx yyy
    112 


sshd doesn't start. With debug mode:
$ /usr/sbin/sshd -d 
/etc/ssh/sshd_config line 103: keyword AuthenticationMethods extra arguments at 
end of line
/etc/ssh/sshd_config line 106: keyword AuthenticationMethods extra arguments at 
end of line
/etc/ssh/sshd_config line 110: keyword AuthenticationMethods extra arguments at 
end of line
/etc/ssh/sshd_config: terminating, 3 bad configuration options

Cheers,
Daniel
