25.3. Setting up the Challenge-Handshake Authentication Protocol
After configuring an ACL and creating an iSCSI initiator, set up the Challenge-Handshake Authentication Protocol (CHAP). For more information on configuring an ACL and creating an iSCSI initiator, see Section 25.1.6, “Configuring ACLs” and Section 25.2, “Creating an iSCSI Initiator”.
The CHAP allows the user to protect the target with a password. The initiator must be aware of this password to be able to connect to the target.
Procedure 25.8. Setting up the CHAP for target
- Set attribute authentication:
/iscsi/iqn.20...mple:444/tpg1>set attribute authentication=1Parameter authentication is now '1'. - Set userid and password:
/iscsi/iqn.20...mple:444/tpg1>set auth userid=redhatParameter userid is now 'redhat'./iscsi/iqn.20...mple:444/tpg1>set auth password=redhat_passwdParameter password is now 'redhat_passwd'.
Procedure 25.9. Setting up the CHAP for initiator
- Edit the
iscsid.conffile:- Enable the CHAP authentication in the
iscsid.conffile:#vi /etc/iscsi/iscsid.confnode.session.auth.authmethod = CHAPBy default, thenode.session.auth.authmethodoption is set toNone. - Add target user name and password in the
iscsid.conffile:node.session.auth.username = redhat node.session.auth.password = redhat_passwd
- Restart the
iscsidservice:#systemctl restart iscsid.service
For more information, see the
targetcli and iscsiadm man pages.
