User jack logs in to host solaris and then attempts to log in to host oracle using ssh. He receives the following error message:
The authenticity of host oracle (192.168.1.22) can't be established. RSA key fingerprint is 3B:23:a5:6d:ad:a5:76:83:9c:c3:c4:55:a5:18:98:a6
Are you sure you want to continue connecting (yes/no)?
Which two are true?
The fingerprints are used to guard against man in the middle attacks. Since ssh logins usually work over the internet (an insecure connection), someone could hijack your connection. When you try to log into yourmachine.com, he could get 'in the middle' and return your challenge as if he was yourmachine.com. That way, he could get hold of your login password.
To make this attack harder, ssh stores the fingerprint of the server's public key on the first connection attempt. You will see a prompt like:
The authenticity of host 'eisen (137.43.366.64)' can't be established.
RSA key fingerprint is cf:55:30:31:7f:f0:c4:a0:9a:02:1d:1c:41:cf:63:cf.
Are you sure you want to continue connecting (yes/no)
When you enter yes, ssh will add the fingerprint to your known_hosts file. you will see
Code:
Warning: Permanently added 'eisen, 137.43.366.64' (RSA) to the list of known hosts.
The next time you login, ssh will check whether the host key has changed. A changing host key usually indicates a man in the middle attack, and ssh refuses to connect.
A local repository is available on this system and you need to enable clients to access this repository via HTTP. The repository information is:
PUBLISHERTYPESTATUSURI
solarisoriginonlinehttp://sysA .example.com
Identify two of the steps that are required to make the local repository on this server available to the client via HTTP.
A: Configure the Repository Server Service
To enable clients to access the local repository via HTTP, enable the application/pkg/server
Service Management Facility (SMF) service.
# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repoSolaris11
# svccfg -s application/pkg/server setprop pkg/readonly=true
E: Use pkg.depotd to serve the repository to clients.
Start the Repository Service
Restart the pkg.depotd repository service.
# svcadm refresh application/pkg/server
# svcadm enable application/pkg/server
To check whether the repository server is working, open a browser window on the localhost location.
To confirm the IP addresses and netmasks have been correctly configured on the network interfaces, which command(s) should you use?
Show address information, either for the given addrobj or all the address objects configured on the specified interface, including the address objects that are only in the persistent configuration.
Example:
# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
lo0/v6 static ok ::1/128
Review the non-global zone configuration displayed below:
The global zone has 1024 MB of physical memory. You need to limit the non-global zone so that it uses no more than 500 MB of the global zone's physical memory. Which option would you choose?
Add a memory cap.
zonecfg:my-zone> add capped-memory
Set the memory cap.
zonecfg:my-zone:capped-memory> set physical=50m
End the memory cap specification.
zonecfg:my-zone:capped-memory> end
You need to know the IP address configured on interface net3, and that the interface is up. Which command confirms these?
Show address information, either for the given addrobj or all the address objects configured on the specified interface, including the address objects that are only in the persistent configuration.
State can be: disabled, down, duplicate, inaccessible, ok, tentative
Example:
# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
lo0/v6 static ok ::1/128
