Host key verification failed error

HI

i am getting host key verification failed error.

Code:
[root@pe1zz1 scripts]# cat id_rsa.pub | ssh root@10.110.51.245 'cat >> .ssh/authorized_keys;exit;'
cat: id_rsa.pub: No such file or directory

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
e3:7c:d9:f2:3e:f1:9a:58:17:48:89:f8:62:ae:31:fc.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
RSA host key for 10.110.51.245 has changed and you have requested strict checking.
Host key verification failed.

i have googled and found the way out to fix the problem which mentioned below

Code:
sed -i '1d' ~/.ssh/known_hosts

but i am not sure the after affect of this. as i have to work live servers.

is this the safe way ?
please let me know the after affect of this ?

Regards,
scriptor

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
ssh(1), ssh-agent(1), sshd(8) OpenSSH 14 November 1999 SSH-COPY-ID(1)
