設定 Linux 主機的鑑別

您可以為 Linux 主機設定單向 CHAP 鑑別。

開始之前

系統支援單向 CHAP 鑑別，其中，系統會鑑別主機 iSER 起始器。

如果要設定 Linux 主機的鑑別，請遵循下列步驟：

1. 使用適當的編輯器，開啟 /etc/iscsi/iscsid.conf 或 /etc/iscsid.conf。
2. 移至 CHAP 設定段落。

   下列範例顯示輸出：

   #*************
   #CHAP Settings
   #*************
   
   #To enable CHAP authentication set node.session.auth.authmethod
   #to CHAP. The default is None.
   #node.session.auth.authmethod = CHAP
   
   #To set a CHAP username and password for initiator
   #authentication by the target(s), uncomment the following lines:
   #node.session.auth.username = username
   #node.session.auth.password = password
   node.session.auth.username = rhel_username
   node.session.auth.password = xxxxxxxxxxxxx
   #To set a CHAP username and password for target(s)
   #authentication by the initiator, uncomment the following lines:
   #node.session.auth.username_in = username_in
   #node.session.auth.password_in = password_in
   node.session.auth.password_in = yyyyyyyyyyyyy
   #To enable CHAP authentication for a discovery session to the target
   #set discovery.sendtargets.auth.authmethod to CHAP. The default is None.
   #discovery.sendtargets.auth.authmethod = CHAP
   discovery.sendtargets.auth.authmethod = CHAP
   #To set a discovery session CHAP username and password for the initiator
   #authentication by the target(s), uncomment the following lines:
   #discovery.sendtargets.auth.username = username
   #discovery.sendtargets.auth.password = password
   
   #To set a discovery session CHAP username and password for target(s)
   #authentication by the initiator, uncomment the following lines:
   #discovery.sendtargets.auth.username_in = username_in
   #discovery.sendtargets.auth.password_in = password_in

3. 設定單向鑑別。
   1. 設定 CHAP 使用者名稱與密碼給您的起始器名稱。
      1. node.session.auth.authmethod = CHAP
      2. node.session.auth.username = <initiator's user name>
      3. node.session.auth.password = <CHAP secret for host>
   2. 設定探索階段作業 CHAP 使用者名稱與密碼給您的起始器名稱。
      1. discovery.sendtargets.auth.authmethod = CHAP
      2. discovery.sendtargets.auth.username = <initiator's user name>
      3. discovery.sendtargets.auth.password = <CHAP secret for host>
   3. 儲存這些設定。您必須登出任何現行階段作業，並重新探索系統 iSER 目標，以便讓 CHAP 密碼生效。
