Hello list,
As suggested on IRC, I'm posting here to report a problem with the
iptables plugin.
I have tried collectd 5.0.1 from source, the 5.0.1 Gentoo ebuild, and
4.10.4 from source, with the same result:
ERROR: lt_dlopen ("/opt/collectd/lib/collectd/iptables.so") failed:
file not found. The most common cause for this problem are missing
dependencies. Use ldd(1) to check the dependencies of the plugin /
shared object.
Unable to load plugin iptables.
The file exists in all cases, and ldd dependencies are all met. strace
reveals nothing particularly wrong with the loading of the module:
(note: the path to iptables.so is different here, this is from the
Gentoo ebuild whereas the above is from source)
[pid 870] open("/usr/lib/collectd",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3
[pid 870] getdents64(3, /* 13 entries */, 32768) = 408
[pid 870] lstat64("/usr/lib/collectd/iptables.so",
{st_mode=S_IFREG|0755, st_size=9288, ...}) = 0
[pid 870] open("/usr/lib/collectd/iptables.so", O_RDONLY) = 4
[pid 870] read(4,
"\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0`\v\0\0004\0\0\0"...,
512) = 512
[pid 870] fstat64(4, {st_mode=S_IFREG|0755, st_size=9288, ...}) = 0
[pid 870] mmap2(NULL, 12316, PROT_READ|PROT_EXEC,
MAP_PRIVATE|MAP_DENYWRITE, 4, 0) = 0xb7551000
[pid 870] mmap2(0xb7553000, 8192, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 4, 0x1) = 0xb7553000
[pid 870] close(4) = 0
[pid 870] munmap(0xb7551000, 12316) = 0
The system is running a monolithic Linux-VServer kernel, version
2.6.38.7-vs2.3.0.37-rc15 on i686, with PaX (but no untoward flags on
iptables.so).
I am quite at a loss to explain and solve this issue, any pointers
would be appreciated.
Cheers
