1 | /* |
2 | * Print the kernel X.25 accounting file, in the following format: | |
3 | * month | |
4 | * day | |
5 | * hour:min - call start time | |
6 | * duration - call duration in seconds | |
7 | * user - name of user who placed the call | |
8 | * in/out - incoming or outgoing call flag | |
9 | * address - X.121 address | |
10 | * host - host name associated with address, if known | |
11 | * rev/--- - reverse charge flag | |
12 | * packet size - packet size in bytes | |
13 | * user data - 4 bytes of user data (protocol), | |
14 | * ITI calls appear as x29d, EAN 1&2 as ean1/ean2, | |
15 | * others as 4 hex digits. | |
16 | * packets sent | |
17 | * packets received - number of packets sent and received. | |
18 | * | |
19 | * Not the nicest format for people, but it is assumed that the | |
20 | * output will be further processed before people see it. | |
21 | * The idea here is to convert the raw data to a form | |
22 | * convenient for shell or awk scripts. | |
