  4. USING WINSCP PROGRAM & LOADING MASTER SOFTWARE

  5. Settings in Windows PC • In Windows PC, a folder named karel is created. • Then under karel directory, folders etc, karel_bin, karel_home_conf and karel_sbin are created. • Then bash.bashrc.local file is copied under etc folder. • The master software z_new_x.rpm is copied under karel_bin folder. • dsinit.conf and pbxcomm.conf files are copied under karel_home_conf folder. • arpsave,check, dsinit, dslog, start, stop files are copied under karel_sbin folder.

  6. Now we are ready to implement the process in Linux PC ( PCU200 ) by using the WinSCP Program...

  7. USING WINSCP PROGRAMAFTER INSTALLATION • The master software (software of the Linux PC) of the system is loaded by using the program WinSCP. • First, the program WinSCP is installed on the Windows-based PC that is on the same network, • Then the Linux PC is accessed through the program WinSCP. IMPORTANT: Necessary files are supposed to be copied to particular folders in the Linux PC. *** If those files are copied to wrong locations or some files aremissing, then the DS200L system fails to operate.

  8. WINSCP ► After the installation of the program WinSCP is over, the followingwindow appears. The IP address of the Linux PC is typed as theHostname. The username and the password are entered. Username: root Password:ds200L

  9. WINSCP ► Those settings are saved with a specific name by clickingthe “Login” icon.

  10. WINSCP ► The left half of the window that opens shows the folders on theWindows PC, while the right half displays the ones on the Linux PC(PCU200).

  11. First operation to do in WinSCP • The folders created in Windows PC ( karel_bin, karel_sbin,...) are copied to the Linux PC one by one. • Then r-w-x ( read-write-execute ) authorities of regarding folders are checked and set by right-clicking .

  12. WINSCP ► The etc folder under the masterdirectory that has been created on the Windows PC is accessed.

  13. WINSCP ► The file bash.bashrc.local, which is under the etc folder in WindowsPCis copied to the etc folder in the Linux PC.

  14. WINSCP • Under etc folder in Linux PC, the file “ hosts “ is double clicked.

  15. WINSCP • In the hosts file, IP address of the redundant PCU is entered which corresponds to X2.

  16. WINSCP- Loading Master Software ► The master software that is to be loaded is copied to the karel/binfolder on the Windows PC which is at the left side of the figure below. Then thismaster software is copied to the karel/bin folder on the PCU200 which is atthe right side of the figure below. As the figure below shows,there may beseveral master programs under the karel/bin folder.

  17. WINSCP- Loading Master Software • After copying the new master software to the PCU200 side, in the cd/karel/bin prompt the command “ rpm –ivh –force z_new_23.rpm “ is entered. • This command automatically upgrades the master software in dsinit.conf file. *** After this command the system should be stopped using the stop command.

  18. WINSCP- Loading Master Software > We can check the files in karel/bin folder by the command ls and verify the new software exists. > check z_new_x command makes the setting of r-w-x authorities of new master software. *** After this command the system should be started using the start command.

  19. WINSCP- Loading Master Software ► The master software that is to run on the system can be checked by right clicking the file karel/home/conf/ dsinit.conf and selecting “Edit” in the menu. NOTE: Same operation can also be done by the command mceditdsinit.conf in the karel/home/conf command line of the SSH Secure Shellprogram.

  20. WINSCP- Loading Master Software ►Once the file karel/home/conf/dsinit.conf is accessed, the masterprogram to run on the system can be checked through the VERSION parameter.

  21. WINSCP- Loading Master Software ► Then, read, write and execute (r-w-x) permissions of the files are set by the command check z_new_x of the SSH Secure Shell program. ► After the loading has been completed, the exchange is initiated by the start command of the SSH Secure Shell program.

  22. UPDATING THE MASTER SOFTWARE OFTHE SYSTEM ► When updating the master software, there is no need to copy the file bash.bashrc.local, which is under the folder etc, to the Linux PC, as performed during the loading of the master software for the first time. ► The procedure to be followed afterwards is the same as the one that is followed when loading the master software.

  23. USING SSHSECURE SHELL PROGRAM

  24. STEPS AFTER THE INSTALLATION 1)The SSH Secure Shell program is used to manage thesystem and to access master and slave Linux PCs (PCU200)in the DS200L system. The default window that opens afterthe program is loaded is shownbelow.

  25. SSH SECURE SHELL 2)It is possible to define new profilesthrough that window. Master and slave Linux PCs can be defined by this way. That would make later connections easier.

  26. SSH SECURE SHELL 3) Define the Master PC, that is, the PCU200 running in the system.

  27. SSH SECURE SHELL 4) Edit the profile settings by selecting Profiles/ Edit Profiles in themenu.

  28. SSH SECURE SHELL 5) Enter the IP address of the Master PC into the Host Name box. The necessary settings are completed by typing root in the UserName box.

  29. SSH SECURE SHELL 6) Make the connection to the Master PC by selecting Profiles/ Master.

  30. SSH SECURE SHELL 7) Enter ds200L as the password.

  31. SSH SECURE SHELL 8) Proceed to the root line, as shown below.

  32. IMPORTANT COMMANDS USEDIN SSH SECURE SHELLPROGRAM

  33. COMMANDS 9) The DS200L system is halted by the command stop. On the other hand, the system is powered OFF and then ON again upon the command start, so that the system resarts .

  34. COMMANDS 10 ) As shown below, the master software of the system can be viewed and changed in the file dsinit.conf that is accessed through thecommand mcedit dsinit.conf.

  35. dsinit.conf • The parameter VERSION specifies the master software that is to run on the DS200Lsystem.

  36. COMMANDS 11) As shown below, IP connections of the system is checked through the file pbxcomm.conf that is accessed through the command mcedit pbxcomm.conf.

  37. pbxcomm.conf • Connections of the system with towers (cc) and theDCC block (dcc)canbe checked andchanged withinthe file pbxcomm.conf. • The order of towersareautomatically determinedbythe system with respect to the order each ofthem istyped, i.e., the towerthat is typed first is automaticallydefined bythesystem as the first tower,and so on.

  38. pbxcomm.conf • When any of the towers is reset, connection to that tower is automatically established.When a new tower is identified to the system,a connection is established if the IP address of the tower is present in thefile pbxcomm.conf.

  39. pbxcomm.conf NOTE: Those IP addresses can also be identifiedto the system by right clicking the filepbxcomm.confin WinSCP and selecting the Edit option.

  40. COMMANDS 12) Times when the system was shut down or powered ON, locations Thesystem has established connection, and some version information can be viewed through the command dslog. The log information is displayed page by page for convenience, by the command dslog |more .

  41. COMMANDS 13) The command date allows the system time to be displayed and date–s xx:yy allows it to be changed.

  42. COMMANDS 14) The command ifconfigof the program SSH Secure Shell is used to change the IP addresses of the master and slave PCU200s whenneeded. After typing the command ifconfig and pressing the Enter key,the Ethernet devices that have been defined on the PCU200 aredisplayed. New IP address of the desired Ethernet device is typedthrough the commandifconfig.

  43. COMMANDS 15 ) Set the read, write and execute (r-w-x) permissions of the files through the command check r_aca_x.

  44. COMMANDS 16) IP and MAC addresses of the LAN Adaptor cards in TW200 towers have been registered in the file arpsave. Content of the arpsave file can be displayed through the command mcedit arpsave.

  45. arpsave NOTE: Content of the file arpsave also can be displayed by clicking it in the program WinSCP and selecting “Edit” option.

  46. COMMANDS 17) The command dslog tar allows the system log files (curr.log,prev.log, etc.) in the Linux PC to be zipped and converted into files with.rar extension. The file log.tar.bz that is created under the folderkarel/home/sbin would suffice when the log file is requested by thesystem.

  47. IDEA- DS200L SYSTEM CONNECTION

  48. IDEA – DS200L Connection • IP address of the active PCU200 computer at that time is typed in the “NetConsole Server” tab in IDEA to establish a connection.

  49. IDEA – DS200L Conneciton • After the connection with the IDEA of DS200L system is established, Configuration window shown below can be displayed. Several parameters of the DS200L system can be set.

  50. IDEA - DCC CONNECTION
