End, is separately turned on tunnel port in local side and server-side.
Ssh-4-o ServerAliveInterval=1-o ServerAliveCountMax=5-o
StrictHostKeyChecking=no
- o UserKnownHostsFile=/dev/null-o ExitOnForwardFailure=yes-f-N-R%
(remoteport) s:localhost:% (localport) s% (username) s@% (host) s
Here remoteport represents server-side Linux system local port, and localport represents client linux
The local port of system.When server-side sends data to remoteport, the tunnel ssh will forward data to localport, from
And realize also can normal communication when server-side can not actively connect client.
5.iscsi service starts successfully or after the tunnel ssh opens successfully, passes through ssh protocol entry to server-side linux
System, and remotely execute following iscsi order:
# scans client ip, and finds iscsi target
iscsiadm--mode discovery--type sendtargets--portal$scstserver
Purview certification mode is arranged in #
Iscsiadm-m node--targetname $ target--op=update
-- 2>&1 of name=node.session.auth.authmethod--value=CHAP
Login username is arranged in #
Iscsiadm-m node--targetname $ target--op=update
-- 2>&1 of name=node.session.auth.username--value=vdi
Login password is arranged in #
Iscsiadm-m node--targetname $ target--op=update
-- 2>&1 of name=node.session.auth.password--value=$ password
# executes login
iscsiadm-m node--targetname$target-p$scstserver--login
Here $ scstserver is client ip (unlatching of the tunnel ssh is then server-side local ip), and $ target is client
Hold iscsi target title.After above-mentioned iscsi register success, server-side Linux system is local will to there is similar scsi
Disk unit:
/ dev/disk/by-path/ip-% (scstserver) s:3260-iscsi-% (target) s-lun-0
