Tell me please is there any way to resolve this issue without installing a login manager please?
I've enabled the auto login for startx, following the steps from the beyond link:
How to make auto login work in Ubuntu? (no display manager)
Auto login is functioning now.
On the device is a command line installation from Minimal Lubuntu 16.10 mini.iso. without any desktop, only the Kernel and some restricted modules. The only environment installed is fluxbox.
After booting in Fluxbox, I can't open gnome-terminal at all, until I will not do the next steps. xterm can start.
ctrl+alt+del in the running Fluxbox, it will redirect me for a second-two in tty, but because auto login is enable it will redirect me back automatically from tty1 to Fluxbox. So, in order to remain in tty I will keep pressing continuously ctrl+c.
Now, being in tty I will
sudo -i
su myusername
startx
Being again in fluxbox, I can run the terminal normally.
Do you please have any clues please, why I can't open the terminal without doing the above?

Thank you.
I am seeing a similar problem since upgrading to Ubuntu 16.10. I discovered that I can fix the environment and start gnome-terminal like this:
dbus-update-activation-environment --systemd --all
gnome-terminal &
If that doesn't work, then you could try this:
dbus-launch gnome-terminal &

In order to have my site running on a webserver i have to manualy login into it with these commands:
ssh IP
add password
cd chn
source bin/activate
cd chn
python3 manage.py runserver IP:80
And that is it! How i can do all this process to run in the background?
PS. The server is running on Linux/Ubuntu14.0 i think. If i put & at the end of each line, i will see them in my terminal, but i am afraid that it will stop all, when i close my mac/termina etc.

I'm running an rsync daemon (providing a mirror for the SaneSecurity signatures).
rsync is started like this (from runit):
/usr/bin/rsync -v --daemon --no-detach
And the config contains:
use chroot = no
munge symlinks = no
max connections = 200
timeout = 30
syslog facility = local5
transfer logging = no
log file = /var/log/rsync.log
reverse lookup = no
[sanesecurity]
comment = SaneSecurity ClamAV Mirror
path = /srv/mirror/sanesecurity
read only = yes
list = no
uid = nobody
gid = nogroup
But what I'm seeing is a lot of "lingering" rsync processes:

(it's currently 15:30)
So there's processes (not even having dropped privileges!) hanging around since 15:10, 15:13 and the like.
And what are they doing?
Let's check:
# strace -p 5304
strace: Process 5304 attached
select(4, [3], NULL, [3], {25, 19185}^C
strace: Process 5304 detached
<detached ...>
# strace -p 5797
strace: Process 5797 attached
select(4, [3], NULL, [3], {48, 634487}^C
strace: Process 5797 detached
<detached ...>
This happended with both rsync from Ubuntu Xenial as well as installed from PPA (currently using rsync 3.1.2-1~ubuntu16.04.1york0 )
One process is created for each connection. Before a client selects the module the process does not know if it should drop privileges.
You can easily create such a process.
nc $host 873
You will notice that the connection will not be closed after 30s because the timeout is just a disk i/o timeout. The rsync client have a --contimeout option, but it seems that a server side option is missing.
In the end, I resorted to invoking rsync from (x)inetd instead of running it standalone.
service rsync
{
disable = no
socket_type = stream
wait = no
user = root
server = /usr/bin/timeout
server_args = -k 60s 60s /usr/bin/rsync --daemon
log_on_failure += USERID
flags = IPv6
}
As an additional twist, I wrapped the rsync invocation with timeout, adding another safeguard against long-running processes.
I'm facing an issue.
We have a clean script using to clean old files, and sometimes we need stop it for and will start it again later. Like the below processes. We use kill -STOP $pid and kill -CONT $pid in check.sh to control the clean.sh, $pid is all the pids of clean.sh (at there, they are 23939, 25804):

Once the check.sh stopped clean.sh, hours later, check.sh started clean.sh, but there is a strange thing, after a stop and continue, there is a child process 'ls -d ....', it's still stopping.
Could you tell me if it's caused by wrong use of the signal? And how can I modify it?
ok, same like my description is not clear, my bad English...
Not sure what's the reason, but there is a way to sovle it:
kill -CONT $pid
pkill -CONT -P $pid
This will continue the child process.
Trying to stop Apache2 service, but get PID error:

Trying to kill, those processes:

but they get re-spawned again:

And though the processes are running i can't connect to the server on port 80. /var/log/apache2/error.log.1 has no new messages when i do the kill -9.
Before I tried to restart everything worked perfectly.
Running on Debian: Linux adara 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux
UPD:
also tried apache2ctl:
#/usr/sbin/apache2ctl -k stop
AH00526: Syntax error on line 76 of /etc/apache2/apache2.conf:
PidFile takes one argument, A file for logging the server process ID
Action '-k stop' failed.
The Apache error log may have more information.
but there is no pid file in /var/run/apache2
I'm new to linux, looks like it has to do something with startup scripts, but can't figure out what exactly.
Below is the command to find out the process running on port 80
lsof -i tcp:80
Kill the process with PID.Restart the system once to check if their is any start up script executing and using the Port 80 which is preventing you to start your service.
For start up scripts you can check
/etc/init.d/ or /etc/rc.local or crontab - e
You can try Apache official documentation for stop/restart operations.

I connect to a remote server using SSH
I was compiling using cmake and then make, it's not common to have a progress percentage in compilation process, but this time it has. I was watching the compilation process until my internet connection failed, so puTTY closed the session and I had to connect again to my server. I though that all the progress was lost, but i first make sure by watching the processes list by ps aux command, and I noticed that the processes related to the compilation are still running:

I would like to know if is possible to watch the current progress of the compilation by watching the previously closed terminal output. Something similar like 'cat /dev/vcsa1' or something
As per the comment above, you should have used screen.
As it is, you could try to peek at the file descriptors used by sshd and the shell that you started, but I don't think this will get you very far.
