I have several ssh keys in the ~/.ssh directory of my desktop machine. As a result whenever I try to connect to a system which uses password authentication I get the "Too many authentication failures" error. Yes, I know I can get round this by setting PreferredAuthentications but this is rather a nuisance to have to do individually for all systems that use password authentication. It also means that I have to do it for a 'casual' ssh access to a system which I'm unlikely to access more than once. Is there any way around this problem? -- Chris Green

Hi, Just feel curiously. I am using sun SSH 1.0.1 and 1.1 on different machines, and get different password promts as follows. ------------------------------------ root> ssh -V SSH Version Sun_SSH_1.0.1, protocol versions 1.5/2.0. root>ssh 10.193.106.90 root at 10.193.106.90's Password: ------------------------------------ root> ssh -V Sun_SSH_1.1, SSH protocols 1.5/2.0, OpenSSL

...g it doesn't work, since the client will not in fact request it (by default). I was fooled by the statement in the ssh man page about HostbasedAuthentication that the client supports this by default (well it is set to "yes"). While it supports it, it seems that the default value for PreferredAuthentications is set to: publickey,password,keyboard-interactive,hostbased so it starts prompting for a password before getting that far. Setting the list to: publickey,hostbased,password,keyboard-interactive in ssh_config seems to do the trick, but even having added this I still can't find anything...

Hello, We tested OpenSSH 3.9 in Hp-UX platforms for Passwordauthentication under PAM modules. We started the SSH Daemon with following settings: Usepam yes ChallengeResponseAuthentication yes passwordauthentication yes The client is invoked with ssh -o'Passwordauthentication yes' localhost -vvv. The debug traces shows that the authentication suceed as keyboard-interactive.

Hi, I've got a remote system that was down and came back up. I'm trying to get into the system, but when I do I get timed out. I forced it to a keyboard interactive to speed things up: ssh -o PreferredAuthentications=keyboard-interactive -vvv tuc at 10.2.0.2 but I get : debug1: waiting for SSH2_MSG_NEWKEYS debug1: newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: done: ssh_kex2. debug1: send SSH2_MSG_SERVICE_REQUEST debug1: service_accept: ssh-userauth debug1: got SSH2_MSG_SERVICE_ACCEPT debug1: auth...

...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 user at 127.0.0.1 > $ ssh -o LogLevel=INFO -o PreferredAuthentications=publickey -o IdentitiesOnly=yes user at 127.0.0.1 > Permission denied (publickey,password). The fix is to add LogLevel=INFO to the ssh command, which is a sane default since ssh-copy-id act...

As an experiment I set up Challenge/response authentication on a Linux system with PAM using a pam_opie module (this module works fine with console logins and su). I can log into the box using the opie password, *but* it does not give me the challenge - which can make things a little tricky :-) I can well believe this might be a fault in the PAM pam_opie module I am using, so has anyone got

...0 lines in my known hosts but in reality I only ssh to a dozen or so systems. All the redundant ones are because I have a mixed population of Raspberry Pis and such on my LAN and they get rebuilt fairly frequently and thus, each time, get a new entry in known_hosts. As a result I have to set 'PreferredAuthentications password' for some systems because there are *loads* of redundant keys which cause login to fail otherwise. -- Chris Green

Hello I think I've found a bug but since no one replied to me on comp.security.ssh, I'll try my luck here. On my client, PreferredAuthentications is set to publickey,password. When using the commands option in authorized_keys file like command="ls" ssh-dss <key>... it is supposed to connect using the private key associated with <key>, perform ls and then quits. Until here everything is fine. Then I tried to delete the...

It appears that /etc/ssh/ssh_config enforces policy on local users in addition to its documented role as provider of defaults. $ ssh -V OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f $ cat .ssh/config Host localhost HostbasedAuthentication yes PreferredAuthentications hostbased $ ssh localhost Hostbased authentication not enabled in /etc/ssh/ssh_config ssh_keysign: no reply key_sign failed Permission denied (publickey,password,keyboard-interactive,hostbased). The situation is rectified by enabling Hostbased authentication in /etc/ssh/ssh_config (as the error m...
