Package: snmpd Version: 5.7.2.1+dfsg-1 Severity: normal Tags: patch Dear Maintainer,
We are managing a Debian box running some LXC containers. These LXC containers have a running snmpd process. These snmp process in LXC containers are visible from the host. Example: ---- cut here ---- lxc-host:~$ sudo lxc-ls --running debian8 ('init' of the container "debian8" is running PID 27570) lxc-host:~$ sudo ps xa|grep ini[t] 1 ? Ss 0:04 /sbin/init 27570 ? Ss 0:03 init [3] (one snmpd process running in the LXC container (PPID: 27570)) lxc-host:~$ sudo ps xaj|grep snmp[d] 27570 28867 28865 28865 ? -1 S 103 4:57 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -g snmp -I -smux mteTrigger mteTriggerConf -p /run/snmpd.pid ---- cut here ---- In such a situation, I've tried "service snmpd start" on the host, but it doesen't work. Because the "start-stop-daemon" in the file /etc/init.d/snmpd don't have "--pid-file" option, then it beleve that snmpd already running. But the snmp process is LXC containers' one, not for the host. I attached a patch to fix this problem. -- System Information: Debian Release: 8.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=ja_JP.UTF-8, LC_CTYPE=ja_JP.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages snmpd depends on: ii adduser 3.113+nmu3 ii debconf [debconf-2.0] 1.5.56 ii libc6 2.19-18+deb8u3 ii libsnmp-base 5.7.2.1+dfsg-1 ii libsnmp30 5.7.2.1+dfsg-1 ii lsb-base 4.1+Debian13+nmu1 snmpd recommends no packages.
