Hi. I m trying to configure access to a CVS machine (SunOS5.8) from another similar machine(5.8). I want access to be configured in such a way that - it does not ask for passphrase while accessing/doing any operation. The CVS is accesed over ext protocol, using dsa key. (which is installed in the box). the application is working for my user.id (I can checkout from cVS) and when i swithc to another user id, it does not (I have key installed for this user too). I login to this ID over a sudo (I cannot directly login to box using this id). I login to box using putty, then sudo to this new id. and then there i execute my script taht connects to CVS/checksout code branch. Whjen I try to execute the script - i can find the below error: Host key verification failed. [cc]Apr-24 11:56:48 VersionsSystem- cvs [checkout aborted]: end of file from server (consult above messages if any) [cc]Apr-24 11:56:48 VersionsSystem- problem getting CVSROOT/users; using empty email map The authenticity of host 'cvs-01.itg.discovery.com can't be established. RSA key fingerprint is XXXX (hexa key) Are you sure you want to continue connecting (yes/no)? [cc]Apr-24 11:56:48 VersionsSystem- Host key verification failed. Has anyone ever run into something similar - please help us out . This issue has been open for more than a day now. Thanks much. Sivaram Iyer.
