NetXMS Support Forum

Здравствуйте.

Поступил к нам в коллекцию свитч D-Link DGS-3612. Добавил его в NetXMS, запросил конфигурацию и — netxmsd упал. Запустил с ключом -D 9, ниже последние строки перед вылетом:

Сейчас он стоит с галкой в конфигурации "Не опрашивать по SNMP", иначе NetXMS падает. Ужасно хотелось бы разобраться, что такого там происходит.

Версия NetXMS — 1.0.11

Ещё на всякий случай уточнение. Проблема проявилась на версии 0.2.31. На удачу решил обновиться, но не помогло.

А что выдают следующие запросы:

nxsnmpget -c community device_ip .1.3.6.1.2.1.2.1.0
nxsnmpwalk -c community device_ip .1.3.6.1.2.1.2.2.1.1
nxsnmpwalk -c community device_ip .1.3.6.1.2.1.31.1.1.1.18
nxsnmpwalk -c community device_ip .1.3.6.1.2.1.31.1.1.1.1
nxsnmpwalk -c community device_ip .1.3.6.1.2.1.2.2.1.2

Pervaja komanda dolzna bila bit' nxsnmpget, a ne nxsnmpwalk.

Esche vopros - esli mozno, zapustite netxmsd pod gdb:

gdb netxmsd

poluchite prompt gdb>

tam komanda

run

posle crasha budet obpjat' prompt gdb>

napishite komandu

bt

i prishlite rezul'tat.

Poprobujte zamenit' src/server/core/snmp.cpp na prilozennij i peresobrat' server.

OID .1.3.6.1.2.1.2.1.0 - eto kolichestvo interfejsov, a DLink vozvraschaet otricatel'noe chislo! Server ne bil rasschitan na takoe Dobavil proverku na takoj sluchaj, teoreticheski dolzno bit' vse horosho.

С ума сойти. Неудивительно, что сервер растерялся.
Большое спасибо, Виктор, сегодня вечером попробую пересобрать сервер.

Ещё раз спасибо большое, Виктор, патч помог.
