129. 129 OBTAINING LOG FILE LOG FILE OF THE SYSTEM ETHEREAL LOG HYPERTERMINAL LOGS OBTAINED FROM DCC BLOCK LOGS OF THE PPC SS7 CARD

130. 130 LOG FILE OF THE SYSTEM

131. 131 LOG FILE OF THE SYSTEM When it’s required to obtain log file from DS200L system: Establish a SSH Secure Shell connection At the root command line, type dslog tar and press ENTER key. All the files under the directory karel/home/log are zipped and a new file named log.tar.bz2 is formed. It will be necessary and enough to send this file to Karel.

132. 132 In order to follow the flowing of the system’s log at that moment, you can use “dslog” command at the SSH Secure Shell program. Thanks to “dslog” command, system’s start&stop times, active towers and some information about the versions can be observed. By the “ dslog |more “ command, these logs can be viewed page by page. LOG FILE OF THE SYSTEM

133. 133 LOG FILE OF THE SYSTEM

134. 134 Log of IDEA Program: Log of the IDEA program also exists in the system’s log. At DS200L systems, normally, analyzing the system’s log will be enough. But it may not be easy to view the IDEA log inside the system’s log when the size of system’s log is too big. If necessary, IDEA log can be analyzed seperately. Obtaining the log file of IDEA program at DS200L systems is similar to DS200 systems. When IDEA program is run, a text based file under the directory which IDEA program is installed is formed automatically. In this file, log files of that current session of the IDEA are saved. LOG FILE OF THE SYSTEM

135. 135 ETHEREAL LOG

136. 136 Ethereal is a network analyzer and shows IP signaling & speech logs. It is an open source program and can be downloaded easily from internet. Since DS200L system communicates over LAN through TCP/IP, Ethereal logs are useful to observe communication problems in DS200L communication. ETHEREAL LOG IMPORTANT: In order to obtain usable Ethereal logs, programmable network switch or hub is needed.

137. 137 Run SSH Secure Shell program and see the list of ethernet cards at the PCU200 computer by the ifconfig command. ETHEREAL LOG

138. 138 ● “tcpdump” command forms a file in the PCU200 computer. That file contains Ethereal logs. ETHEREAL LOG

139. 139 When there is a problem at the system and log of this problem is required: -Run IDEA program -Double click the LOG icon at the right-bottom side of the IDEA window and reach the log window. After clearing the log window, generate the problem again. -Copy and paste the log messages and save them in a text file in the maintenance computer. LOG FILE OF THE SYSTEM

140. 140 This command is entered as : “ tcpdump -i eth1 –C 10 –s 1500 –w ethereal “ -i ( interface ) : shows which interface ( Ethernet card ) is being used. eth1: shows the “eth1” named ethernet card is being used. -c (capacity ): shows the capacity of logs are saved. Example: -c 10 -> shows the logs will be saved as 10MB sized. -s ( snap ): amount of data for each frame ( in terms of byte). If not defined, it’s 68 byte. -w ( write ) : determines the name of the ethereal file to be saved under the root directory. In the example above, name of this file is written as “ethereal” for easiness. If desired, this file can be saved in another name. ETHEREAL LOG
