[Pkg-net-snmp-devel] Bug#699479: snmpd: In the SNMP run name table process names are truncated to 15 chars

[Robert Waldner]

Package: snmpd
Version: 5.4.3~dfsg-2.7
Severity: normal

Dear Maintainer,

when querying the system for running processes, like, f'rex, apache2, with
OID iso.3.6.1.2.1.25.4.2.1.2.$PID, the resulting string is truncated to 15
characters (16-byte fixed-size buffer, thinking of 0-terminated strings in
C?).
This is quite annoying since some processes have started to include their
full path in this, like apache2:
$ snmpwalk -v 2c -c comm localhost iso.3.6.1.2.1.25.4.2.1.2 | grep apach
iso.3.6.1.2.1.25.4.2.1.2.1483 = STRING: "/usr/sbin/apach"
...

There are also at least those processes whose names are truncated even
though they don't have their path in there:
BackupPC_trashC (BackupPC_trashClean)
console-kit-dae (console-kit-daemon)
enlightenment_f (enlightenment_fm)
hald-addon-stor (hald-addon-storage)
hald-addon-inpu (hald-addon-input)


Maybe this stems from the MIB and not snmpd, but as I don't know anything
about MIBs... please reassign if appropriate.

cheers,
&rw
