Comparing strace between Ubuntu and Debian (lxc launch images:debian/10)
showed that Debian's version doesn't try to connect to the tlsmgr socket
for some reason.
Ubuntu 3.4.10-1:
# grep connect /tmp/strace | grep AF_UNIX
connect(3, {sa_family=AF_UNIX, sun_path="private/tlsmgr"}, 110) = -1 ENOENT (No
such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="private/tlsmgr"}, 110) = -1 ENOENT (No
such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX,
sun_path=@"userdb-523239b8d3d1ae62cb3fa3fd342937ab"}, 42) = -1 ECONNREFUSED
(Connection refused)
connect(4, {sa_family=AF_UNIX,
sun_path="/run/systemd/userdb/io.systemd.DynamicUser"}, 45) = 0
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
Debian 3.4.8-0+10debu1:
# grep connect /tmp/strace | grep AF_UNIX
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_UNIX, sun_path="/run/dbus/system_bus_socket"}, 30) = 0
Those with TCP/25 outbound blocked, you can hit my server on port 465 in
'wrapped' mode (-w):
posttls-finger -t30 -T180 -c -L verbose,summary -w smtp.sdeziel.info:465
