The most common cause of this (once the .pub is properly copied to authorized_keys) is permissions problems. Make sure your .ssh/ directory is mode 700 (rwx------) and your .ssh/authorized_keys file is mode 600 (rw-------) and your home directory is not group-writable. chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys chmod go-w ~ If the remote machine is running RHEL or CentOS, you might also have a SELinux labelling problem. https://bugzilla.redhat.com/show_bug.cgi?id=499343 and http://bugs.centos.org/view.php?id=4959 The workaround is to use the restorecon command, but it is easy to misuse and I am not an expert so I am uncomfortable providing explicit instructions. Check your /var/log/auth.log or similar on the remote host to see if it has messages explaining why pubkey authentication was not allowed. -andy > > Master:~ mediaadmin$ ssh 10.203.33.80 > Password: > Last login: Thu Oct 25 19:04:31 2012 from master > > > Please suggest > > Thanks & regards > Yogesh Kumar > > ________________________________________ > From: Brahma Reddy Battula [[email protected]] > Sent: Thursday, October 25, 2012 6:38 PM > To: [email protected] > Subject: RE: ERROR: ssh-copy-id: command not found IN HADOOP DISTRIBUTED MODE > > I think master machine authorized-key is missed. > > Please do following.. > > ssh-copy-id -i ~/.ssh/id_rsa.pub {IP of Master machine}.. > > Before starting cluster better to check whether ssh is enable or not by doing > ssh {slave or master IP} from Master ( here it should not ask passwd). > > ________________________________________ > From: [email protected] [[email protected]] > Sent: Thursday, October 25, 2012 7:49 PM > To: [email protected] > Subject: RE: ERROR: ssh-copy-id: command not found IN HADOOP DISTRIBUTED MODE > > Thanks All, > > The copy has been done but here comes another horrible issue. > > when I log in as Master > > > ssh Master it asks for Password > > Master:~ mediaadmin$ ssh Master > Password: abc > Last login: Thu Oct 25 17:13:30 2012 > Master:~ mediaadmin$ > > > and for Slave it dosent ask. > > Master:~ mediaadmin$ ssh pluto@Slave > Last login: Thu Oct 25 17:15:16 2012 from 10.203.33.80 > plutos-iMac:~ pluto$ > > > > now if I run command start-dfs.sh from Master logged in terminal it asks for > passwords > > Master:~ mediaadmin$ ssh master > Password: > Last login: Thu Oct 25 17:16:44 2012 from master > Master:~ mediaadmin$ start-dfs.sh > starting namenode, logging to > /HADOOP/hadoop-0.20.2/bin/../logs/hadoop-mediaadmin-namenode-Master.out > Password:Password: abc > Password: abc > Password: > Master: Permission denied (publickey,keyboard-interactive). > Password: > Password: > Slave: Permission denied (publickey,keyboard-interactive). > .... > > > Why is it asking for password when I have configure password less ssh? > And even its not accepting Master password and Slave password.. > > > Please help and suggest > > Thanks & regards > Yogesh Kumar > > ________________________________________ > From: Nitin Pawar [[email protected]] > Sent: Thursday, October 25, 2012 3:31 PM > To: [email protected] > Subject: Re: ERROR: ssh-copy-id: command not found IN HADOOP DISTRIBUTED MODE > > operating system you are using will be of good help to answer your question. > > Normally the command you are looking for is provided by "openssh-clients" > Install this package if not already. > > If installed normally on a redhat system its placed at /usr/bin/ssh-copy-id > > On Thu, Oct 25, 2012 at 3:24 PM, <[email protected]> wrote: >> Hi All, >> >> I am trying to copy the public key by this command. >> >> Master:~ mediaadmin$ ssh-copy -id -i $HOME/.ssh/id_rsa.pub pluto@Slave >> >> I have two machines Master Name is pluto and same name is of Slave.
