NOTE: This article is only meant to be used as a summary of the available commands, and used only by advanced administrators of Director. All commands come with an available question mark ( ?) at the end that will prompt you for the right syntax. LInks to more detailed information are at the bottom of this article.
1: Getting access to the command line interface- CLI:
- Open a SSH session to to the Director box..
- Enter the enable mode by following the steps.
- director > enable
- director #
- Enter the configuration mode by following these steps.
- director # config t
- director (config) #
- TIP: If you do not see this prompt, see KB4829
- Network-related configuration and troubleshooting
- director # sh interfaces
- director # sh interfaces lo ( for the loopback port)
- director # no interface lo shutdown ( to enable the loopback port if it is shut down)
- director (config) # ip name-server DNS-ip-address
- director (config) # ip name-server
- director (config) # ip host <Ipaddress> ( adds a static mapping between the supplied hostname and the address.)
- director (config) # hostname <hostname> ( changes the hostname of Director.)
- director (config) # ip default-gateway
- sh-2.05b# ifconfig -a ( shows information regarding all interfaces on the device - need to activate the linux shell here)
- director (config) # service network restart ( restarts all ethernet ports and their configuration- often used to restart the loop back port- an essential for Director operations)
- Showing the version, the serial number, and hostname of your Director.:
- director > show version
- director > show status
- director > show hosts
- User credential-related commands
- director > show usernames ( will only show the local user database).
- director > show privilege ( shows what privileges your logged-in user has)
- director (xx.xx.xx.xx username <username> disable ( to disable a username from logging in)
- director (config) # username <new username> ( to add a username)
- director (config) # no session <username> ( to terminate a user session.)
- director (config) # enable password "" ( to set the enable password to null)
- director (config) # enable password secret ( to set the enable password to ''secret')
- TIP: See the section on procuring a status of your Director dameons for a way to reset the postgress database.
- Radius commands:
- director show radius
- director (config) # radius-server host xx.xx.xx.xx key secret -----> xx.xx.xx.xx is Server IP
- director (config ) # radius-server retransmit 1
- director (config ) # no ssh server auth permitemptypassword
- NOTE: The first command will lower the number of retransmits to the RADIUS server. The second one will prevent Director from sending a null password to RADIUS before sending the actual password.
- TACACS+ commands.
- tacacs-server host hostname key password
- tacacs-server host hostname port port_number
- tacacs-server host hostname single-connection
- tacacs-server host hostname timeout numh numm nums

- director (config) # configuration switch-to <name of config file>
- director (config) # configuration new test <new config file >
- Archive commands:
- director (config) # archive all <name of archive file>
- director (config) # archive all fetch <name of file> ftp://<ip address>
- director (config) # archive all restore all <name of archive>
- SSL commands:
- director (config) # show ssl appliance-certificate
- director (config) # ssl request-appliance-certificate
- # show ssl appliance-certificate ( when executed on the SG.)
- Restarting Director:
- Troubleshooting with the messages file:
- director # config t
- director # shell
- director # tail -f /var/log/messages
- Working with DNS ( all done in the shell mode)
- sh-2.05b# /etc/init.d/djbdns status ( checks to see if the DNS service is running)
- sh-2.05b# /etc/init.d/djbdns start (Starts the DNS service )
- sh-2.05b# /etc/init.d/djbdns reload ( reloads the DNS service)
- sh-2.05b# dnsip stoppingcom ( procures a list of all possible ip addresses of google.com)
- To disable A DNS server- not in linux shell but in config mode.
- director (config) # no ip name-server 10.125.4.50
- director (config) # wr me
- Procuing a status of Director daemons. Starting and stopping services.
- director # config t
- director # shell
- sh-2.05b# service httpd status
- sh-2.05b# service httpd stop
- sh-2.05b# service httpd start
- sh-2.05b# service director stop ( Do not attempt to exit to the nominal command line while the Director daemons are in a stoppped state! This will cause the CLI to hang, and you will then need a hardware reboot to restart the Director daemons)
- sh-2.05b# service director start
- sh-2.05b# service director status (command does not work)
- sh-2.05b# etc/init.d/djbdns stat ( checks to see if the DNS service is running)
- TIP: The "director start' command will error out on file system-related issues- these are nominal.
- TIP: The 'service tomcat status' commands give you a false negative- use the 'ps aux |grep tomcat' for accuracy.
- /etc/initi.d/tcomcat start |stop
- TIP: tomcat is automaticly started with the http daemon.
- TIP: If Postgress daemon does not start, you may want to use the command "director # monitoring db reset force" to reset it. ( this command is done in config mode) A director reload is required after this command.
- For a more detailed discussion on the essential daemons needed for Director, see 000014650
- CPU status commands.
- Interface management.
- See above under "network related" title
- Working directly with each SG device:
- Show devices max-supported ( shows how many total SGS you can configure)
- Remotely backup a SG.
- director # config t
- director # remote-config backup
- TIP: To set the max backups allowed follow the below command
- director (config remote-config backup) # options 40
- Checking the state and health.
- director # Show devices state.
- director # show monitoring health summary ( gives you a list of all registered SGs, and their status- wether or not Director can connect to them, for example)

- #swapon -s [to get swap state, which should NOT be set by default)
- Taking a PCAP for support.
- director > tcpdump -i ether-0 -c 3
- director > tcpdump start
- TIP: tcpdump will be listening on ether-0
- Example1: This command filters the trace for the 126.96.36.199 address: tcpdump -w file.pcap -s 1550 host 188.8.131.52
- director > standbyp stop
