o Subnet mask: 255.255.255.0 If you want t o retain your existing IP se ttings for this network co nnectio n, click Advanced and Add the a bove as a seco ndary IP conn ection. If it is not convenient to change your PC /workstatio n network addr ess, you can use the ARP -Ping command to reset the con sole server IP address.
You will be p rompted to lo g in. Enter the defa ult administratio n username a nd administra tion password: Username: root Password: default Note Console server s are factor y configured with HTTP S access enabled and HTTP access disab led.
After completing ea ch of the abo ve steps, you ca n return to the confi guration list by cli cking in th e top left corner of the screen o n the Black Box logo.
Click Apply . Since you have cha nged the pas sword you w ill be prompte d to log i n again. This time, use the new password. Note If you are not confident t hat your console server has the current firmwar e rel ease, you can upgrade. Refer to Upg rade Firm ware — Chapter 10 .
The next step is to enter a n IP address for the prin cipal Ethernet ( LAN/Netw ork/Networ k1 ) port on the console s erver ; or enable its DHCP client so that it automatically obtai ns an IP address from a DHCP server on the network it will connect to.
3.3.1 IPv6 config uration You can also configure th e console serv er Network a nd Management L AN Interfaces for IPv6 opera tion: On the Syste m: IP menu select G eneral Settings page and check Enable IPv 6. Then, configu re the IPv6 pa rameters on each Interface page .

To enable a service che ck Enable . For s ome servces you will be as ked to specify the TCP/IP port to be used for thie s ervice. T here are also some serial po rt access pa rameters that yo u.
Black Box provides the SDT Connector Java applet as the recomme nded client software tool . Y ou can use other generic tools such a s PuTTY and S SHTerm. Thes e tools are all described below as well. 3.5.1 SDT Connector Each console server has an unli mited number o f SDT Connector licenses to us e with tha t console ser ver .
To use PuTTY fo r an SSH terminal s ession from a Windows client, enter the cons ole server ’s IP address as the ”Host Name ( or IP address).” To ac cess the co nsole serv er command line, select “SSH” as the pr otocol, and use the default IP Port 22.
3.6.1 Enable the Managemen t LAN The LES15 08 A , LES1408A, LES1416A, LE S1432 A , LES1448 A , LES1308A, LES1316A, LES1332 A , LES1348 A , LES1208A - R2, LES1216A - R2, LES1232A and LES1248A - R2 console serve rs pro vi de a firewall, router, and DHCP server .
Note You can configure the se co nd Ethernet port as eithe r a gateway port or as a n OO B/Failover port ( but not both ) . Make s ure you did not allocate N etw ork 2 as the Failover Interface when you configured the principal Network connection on the Sy stem : I P menu.
Enter the Default Lease t ime and Maxi mum Lease time in seconds. The lease time is the tim e that a dynam ically assigne d IP address is valid befo re the client must request i t again.
By default, the failover is not enabled. To ena ble, select the Netw ork page on t he System: IP menu. S elect the Failover In terface to be used i f the main fai ls.
Click Apply . You hav e selected the failo ver method. It is no t active until you specify t he external sites to be probed to trigger failover, and set up t he failover ports themselves. This is cover ed in Chapter 5 . Note Y ou can configure the seco nd Ethernet port as eithe r a gateway port or as an OO B/Failover port, but not both.
Select Enable Bridging on the System: IP Gener al Settings menu. Select Bridge Interfac es or Bond Interfac es o When bridgin g is enabled, network traffic is forwarded a cross all Et hernet ports w ith no firewall restrictions.
To add to the static ro ut e to the route table of t he system: Select the Route Settings tab on the System: IP General Setting s menu . Enter a meaningful Rou te Name for the route . In the Destination N etwork/Host f ield enter the IP addre ss of the destination net work/host tha t the route provides a ccess to.
Chapter 4 Serial Port, Host, Devi ce & Use r Configuration SERIAL PORT AND N ETWORK HOST Introduction The Black Box console s erver enable s access and control of s erially attached devices a nd networ k attached dev ices ( host s ).
1) Conso le S erver Mode is t he default and this enable s general access to serial console port on the serially attached devices. 2) Device Mode sets the serial port up to communicate with an int elligent serial controlled PDU, UPS, or Enviro nmental Monito r Device (EMD).
Specify a label for the po rt. Select the appropriate Baud R ate , Parity , Data Bits , Stop Bi ts, and Flow Contr ol for each port. (Note: The RS - 485/RS - 422 option is not relevant for console server s .
Logging Lev el This specifies the level of info rmation to be logged and moni tored (referto Cha pter 7 — Alerts and Logging). T elnet When the Telnet service is enabled on the cons ole server , a Telnet client on a Us er or Administrator ’s computer can connect to a s erial device attached to thi s serial por t on the console serv er .
I f the remot e co mmunic ations are tunneled with SDT Connector , then you can use Tel net to securely access these attached devices (refer to the N ote below).
PuTTY can be downloaded at http:/ /www.t ucows.com/previe w/195286.html SSH We r ecommend that you use SSH as the pro tocol where the User or Administrator co nnects to the consol e server (or connects through the co nsole serv er to the attached seria l consoles) over the Internet or a ny other p ublic ne twork.
For a User named “ fred” to access serial po rt 2, when s etting up the S SHTerm or the PuTTY SSH client, instead of typin g username = fred and ssh port = 3002 , the al ternate i s to type username = fred:port02 ( or username = fred:ttyS1) an d ssh port = 22.
Web Terminal Selecting Web Terminal ena bles web browser acc ess to the serial port via Manage : Devices: Serial usin g the Manage ment Conso le's built in AJA X terminal. W eb Terminal connects as th e currently au thenticated Management Cons ole user and does not re - authenticate.
For configuration details, r efer to Chapter 6.6 — Usin g SDT Con nector to Telnet o r SSH con nect to d evices that are s erially at tached t o the conso le server .
4.1.6 Serial Bridging Mode With serial bri dging, the serial da ta on a nominated s erial port on on e console serv er is encapsulated into netwo rk packets and the n transp orted ove r a networ k to a se cond con sole server . It is then represented on its serial port aga in as serial data.
For example, if the com puter attached to s erial port 3 should nev er send anything out on i ts serial console po rt, the Adminis trator can set th e Facility for that port to local0 ( local0 .. local7 are for site local values), and the Priority to critical .
Users can be author ized to access specified co nsole ser ver serial ports and spe cified network- atta ched hosts. These u sers can also b e give n full Administra tor status (wit h full config uration and management and access privileges). To simplify u s er set up, the y can be conf igured as me mbers of Group s.
3. If a user is set up wit h pptd, dialin, ftp or pmshell gr oup membership they will h ave restricted user shell a ccess to the nominat ed m ana ged devices but t hey will not have any direct access to t he con sole server itself. To add this the users mus t also be a member of t he "users" or "admin" grou ps 4.
Note The User Name can contain from 1 to 127 alphanumeric chara cter s ( you can al so use the special characte r s “ - ”, “_”, and “.” ). There are no restrictio ns on the charact ers that you c an us e in the user Password (each can contain up to 254 char acters).
4.3 Authenticat ion Refer to Chapt er 9.1 — Remote Authentication C onfiguration for authentication configuratio n details. 4.4 Network Hosts To access a locally networked computer o r device (referred to a s a Host ), you must identify the Host a nd specify the TCP or UDP ports/ser vices that wil l be used to control that Ho st.
If the console ser ver has been co nfigured with dis tributed Nagio s monitorin g enabled, then you wil l also be presented with Nag ios Settings options to ena ble nominated services on the Ho st to be monitored (refer to Ch apter 10 — Nagios Integration ).
Network Mask 255.255.255.255 If, however, you want to allow all th e users operating from within a specifi c range of IP addresses (for example, any of the thirty addresses from 204.15.5.129 to 204.15.5.158) to be permitted connection t o the nomina ted port: Host /Subnet Address 204.
Select System : Administr ation on Master’s Management Console. Check Gene rate SSH k eys autom atically a nd c lick Apply. Next, you must select wh ether to generate keys using RSA and/or DSA (if unsure, select only RSA ).
Next, you mu st register the P ublic Key as an Authoriz ed Key on the Sl ave. In a ca se that has o nly one Master with multiple Slaves, you only need to uplo ad the one RS A or DSA public key for each Slave. Note Using key pairs can be con fusing since one fil e (P ubl i c Key) fulfills two roles — Public Key and Authorized Key.
Once the SSH connection h as been esta blished, the s ystem asks you to accept the key. Answer ye s and the fingerprint will be added to the list of known host s. For more details o n Fingerprinting, refer to Chapter 15.6 . If the system asks you to s upply a pas sword, then t here is a pro blem with upl oading keys .
Once you hav e added all th e Slave conso le server s, you can assign and access the Slave serial ports and the connecte d devices fro m the Master’ s Management Co nsole menu.
This serial port redirector software is loaded in your desktop PC, and it allows you to use a serial device that’s c onnected to the remo te consol e server as if i t were connected to your lo cal serial port.
Select the connection type for the new conne ction (Serial, Network Ho st, U PS, or RPC) and then select the specific connection f rom the presented list o f configured una llocated hosts/ ports/outlets.
Note To set up a new serially conne cted RPC UPS or EM D device, configure the serial port, design ate it as a Device, t hen ent er a Name and Descriptio n for that device in the Serial & Net w ork: RPC Connections (or UPS Connections or Env ironmental ).

Chapter 15 Advanced Configuration ADVANCED CONF I GURATION Introduction Black Box console server s ru n the embedded Linux op erating system. So Administrator class users can configure the console ser.
# dos2unix /etc/config/rc.l ocal Another s cen ario wou ld be to call anothe r custom scr ipt from the /etc/config/rc. local file, maki ng sure that your custom script wi ll run whenever the sys tem is booted. 15.1.2 Running custom sc ripts when aler ts are trigg ered Whenever an alert gets triggered, specific scripts get called.
15.1.3 Example script - Power Cycli ng on Patte rn Match For example , we have an RP C (PDU) connected to port 1 o n a consol e server and also have some telecommunications devic e c onnected to por t 2 (which is powered by the RPC outlet 3 ).
delete -node is a general scr ipt for deleting a ny n ode you desire (users, groups, hosts, UPSes, e tc.) from the command line. The sc ript deletes t he specified node and shu ffles the rema inder of the node values.
NUM BER=`echo $L ASTFIELD | s ed 's/^[a - zA - Z]*// g'` TOTALNODE=`echo ${1%.*} | sed 's/ (.* )/ 1.total/'` TOTAL=`config - g $TOTALNOD E | sed 's/.* //' ` NEWTOTAL=$[ $TOTAL - 1 ] # Make backup copy of config file cp /etc/config/config.
config - g $RO OTNODE.$LA STFIELDT EXT$((NU MBER+COUN TER)) | while read LINE do config - s "`echo "$LI NE" | s ed - e "s/$L ASTFIELDTEX T$((NUMB ER+ COUNTER))/$LA STFIELDTEXT$( (NUMBER+COUNTE R - 1))/" - e 's/ /=/'`" done let COUNT ER++ done # deleting last user config - d $ROOTNODE.
The above co mmand will c ause the ping - detect script to continuously ping the hos t at 192.168.22.2 which is the r outer. If the r outer crashes , it will no lo nger respond t o ping reques ts. If this ha ppens, the two comma nds pmpower a nd date will run.
15.1.7 Running custom sc ripts when a c onfigurator is invoked A configurator is responsib le for reading the va lues in /etc/config/c onfig.xml and making the appropriate c hanges live. S ome changes ma de by the configurators are part of t he Linux conf iguration itself, such as user p a sswords or ipconfig .
To save the c onfiguration: # /etc/scripts/backup- usb save config- 2 0May To check i f the bac k up was saved correctly: # /etc/scripts/backup-usb l ist If this comma nd does not d isplay "* conf ig - 20May" then there was an error savi ng the configur ation.
This will extract the contents of the previously created backup to /tmp , and then synchr onize the /etc/confi g directory with the copy in /tmp . One problem that can crop up here is that there is not enough room in /tmp to extract files to.

- The portmanager will attempt to execute /etc/ config/scripts/portXX.alert (where XX is the port number, e.g. 0 8) - The script is r un with STD IN containin g the data wh ich triggered t he alert, and S TDOUT redire cted to /dev/null, NO T to the seria l port.
With stty , the changes made to the port only “s tick” until that port is clo sed and o pened again. P eople probably will not want to use stty f or more than initial deb ugging of the seria l connection. If you want t o use stty to configure the port, you ca n put stty commands in /etc/config/scripts/portXX.

15.6.2 Generating Public Keys (Linux) To generate new SSH key pairs use the Linux ss h - keygen co mmand. This will produ ce an RSA or DSA public/privat e key pair and you will be prompted for a path to store the two ke y files, for example, id_d sa.pub (the pu blic key) and id_dsa (the priva te key).
15.6.4 Installing SS H Public Key Authen tication (Li nux) Alternately, the public key can be installed on the unit remotely fr om the linux hos t with the scp utility as follo ws. Assuming the us er on the Management C onsole is ca lled "fred"; th e IP address o f the conso le server is 192.
If the Black Box device selected to be the server will only have one client devic e, then the authorized _keys file is simply a copy of the public key fo r that device. If one o r more devices will b e clients of the server, then the authori zed_keys file wi ll contain a copy o f all of the public key s.
More documentati on on OpenS SH can be fou nd at: http://openssh.org/portable.htm l http://www.openbsd.org/ cgi-bin/man.cgi?query=ssh&sektion =1 http://www openbsd.org/cgi -bin/m an.cgi?query=sshd. 15.6.5 Generat ing public/private keys for SSH (Windows) This section describes ho w to generate and configure SSH keys usin g Windows.
- Execute the P UTTYGEN.EXE pro gram. - Select the desired key typ e SSH2 DSA (you may use RSA or D SA) within the Pa rameters se ction. - It is importan t that you lea ve the passp hrase field b lank.
To automate connection of the SSH tun nel from the client on ever y power - up y ou need to m ake the clients /etc/config/rc.local look like the following: #!/bin/sh ssh - L9001:127.0.0.1:4001 -N - o StrictH ostKeyC hecking=no testuser @<server - i p> & This will run the tunnel redirecting local port 9001 to the server port 4001.
If the host ke y has been le gitimately ch anged, it can be removed f rom the ~/.ssh/ known_hosts file a nd the new finge rprint added. If it has not changed, this i ndicates a ser ious problem that shoul d be investigated immediately.
For simplicity going forw ard, the term private key will be used to re fer to either id_rsa or id_dsa and public key to refer to either id_rsa.pub or id_dsa.pu b. To generate t he keys using Ope nBSD's OpenSS H suite, we use the ssh - k eygen progr am: $ ssh - keygen - t [rsa|dsa] Generating pub lic/private [r sa|dsa] key pair.
then the a uthorized _keys file will contai n a copy of al l of the public keys. RSA and DSA keys ma y be freely mixed in the a utho rized_key s file. For example, assume we al ready have one server, cal led bridge_server , and two sets of keys, for the control_room and the plant_entrance : $ ls /home/user/keys control_r oom control_room.
The consol e server includes OpenSSL. The OpenSSL Project is a collaborative effort to develop a robus t, commercial - grade, f ull - featured, and Open Source toolkit implementi ng the Secure Sockets Layer (SSL v2/v3) and Transport Layer Sec urity (TLS v1) protocols as well as a full - strength general purpos e cryptography libr ary.
15.8.3 Installing the key and certific ate We recommend t hat you use a n SCP (Secure C opying Pro tocol) client to copy fil es securel y to the console s erver unit. T he scp utility is distribut ed with OpenSSH for most Unix distributio ns, while Windows use rs can use so mething like t he PSCP command l ine utility a vailable with P uTTY.
