Backing up an Android phone to an OpenBSD laptop
Hello. I'm just looking for advice, not a howto. I realize this is not an OpenBSD specific topic, but since I'm trying to get Linux and OpenBSD to cooperate, anyone I ask for advice will refer me elsewhere. I want to do backups of my Android phone whenever it is at home. The best software package I know of for this is rsync. I own an ARM development system (a Trim Slice), running Linux, and can therefore compile anything I want for the Android phone (statically linked). I have a couple options, that I can think of: Run rsync's daemon on the phone, from a boot script. Configure hotplugd on OpenBSD to run an rsync client when the phone connects via USB. I like this idea because it reduces needed privileges on my laptop... I trust the phone less than my laptop, so I would rather give my laptop access to the phone than my phone access to my laptop. I dislike this idea because the phone uses 5 watts while charging, and I would prefer to charge it from a household outlet to reduce load on the laptop. The second option is to run rsync's deamon on my laptop, and rsync from the phone via an ifup script that checks the SSID. This works nice because I can charge the phone from an outlet, and do the rsync wirelessly. This is harder to secure though, because I would want the rsync client to have no other access to my laptop. Am I missing other considerations? Which of these two options is better?
Re: current snapshot pipex kernel panic
Thank you! It works as expected. Otherwise the mppe no option is missing from the manual page. 2012/9/26 YASUOKA Masahiko yasu...@yasuoka.net: Hello, On Tue, 25 Sep 2012 16:16:12 +0200 csszep css...@gmail.com wrote: I wanted to try a simple npppd setup and i got a panic.

tmux: create window failed (too many open files)

If you are afraid that somebody will exploit your phone, then exploit rsync, then exploit the openbsd kernel in order to get access to your files, in that case I'd advise taking a deep breath. :)
Re: rc_cmd doesn't pick up overridden functions
Thank you. I found the cause of the problem: the daemon changed its process
name after start so the value in /var/run/rc.d file was wrong. That is why
the stop script didn't work (actually it appeared that start script was
working correctly). I set up correct pexp value and everything worked fine.
Let us consider this as solved.
Sorry for bothering.

Hello all,

with the script above commands like:
/etc/rc.d/my_daemon stop
do not call overridden functions (it can be seen in sh -x and if you

echo in function body). Also I noticed that stop handler (default one as

^${daemon}
to pkill. What am I doing wrong?
In general this works fine, many examples in the tree use this
successfully.
What you show, with the /path/to/daemon etc and my_daemon
filename does not seem likely to be the real path/name, so it would
be better to show *exactly* what you're doing.
Re: tmux: create window failed (too many open files)
Are you running a tmux command from any shell script or cron or anything? There are only two places tmux itself opens /dev/null and they are both after fork so this must be /dev/null passed with imsg from a client. Also please should me output of tmux info.

Re: tmux: create window failed (too many open files)
Hi,
After some tests (on a new tmux server, started with tmux -L test ...), I
could (partially) reproduce the problem.
Partially, because:
in fstat output there are 2 kinds of bugged entries: tty and null
tty: 181 descriptors
null: 320 descriptors
And I arrived to keep descriptors opened against /dev/tty , but not against
/dev/null (for the moment, but I monitor what in my use what generate this...).
This occurs with urlview (textproc/urlview), with a custom url_handler.
Basically urlview take a text in stdin (generally an email), and display a menu
(ncurses) of URLs found in the text. The user choose an URL, and urlview start
a command (in my case, a custom script).
First, my configuration:
$ cat ~/.urlview
# command to invoke for selected URL
COMMAND /home/semarie/.local/bin/urlview_handler.sh
Next, the command started by urlview:
$ cat /home/semarie/.local/bin/urlview_handler.sh
#!/bin/sh
# if TMUX enable, update environment
if [ -n ${TMUX} ] ; then
eval `tmux show-environment | grep -v '^-' | sed 's/=\(.*\)$/=\\1\/'`
unset `tmux show-environment | grep'^-' | sed 's/^-//'`
export `tmux show-environment | grep -v '^-' | sed 's/=\(.*\)$//'`
fi
# check DISPLAY
if [ -n ${DISPLAY} ] ; then
exec chrome $@
fi
# if not DISPLAY
exec lynx $@
And when I launch the command:
$ echo 'http://www.openbsd.org/' | urlview
3 new descriptors against tty are opened and not closed after the command.
There are directly correlate with the 3 tmux show-environment in the script.
I don't remind exactly the purpose of updating the environnement in the
script... should be to keep kerberos ticket or display environnement in
text-mode ... but ?
Additionnaly, running the url_hander alone (without urlview) don't trigger the
problem.
I will disabling the part of updating environment in my script (and if I
always need it, I will recall when something won't work !)
I will post when I have more info.
Please let me known if more informations are needed.
Thanks.

Re: tmux: create window failed (too many open files)
The patch seems to resolv the problem.
Only seems, because I only known to reproduce it for the 'tty' descriptor, but
I hope the 'null' descriptor will be in the same case :-)
But I will use this version for test it.
Thanks a lot.

Re: Backing up an Android phone to an OpenBSD laptop
On 09/25/2012 11:25 PM, Robert Connolly wrote: Hello. I'm just looking for advice, not a howto. I realize this is not an OpenBSD specific topic, but since I'm trying to get Linux and OpenBSD to cooperate, anyone I ask for advice will refer me elsewhere. I want to do backups of my Android phone whenever it is at home. The best software package I know of for this is rsync. I own an ARM development system (a Trim Slice), running Linux, and can therefore compile anything I want for the Android phone (statically linked). I have a couple options, that I can think of: Run rsync's daemon on the phone, from a boot script. Configure hotplugd on OpenBSD to run an rsync client when the phone connects via USB. I like this idea because it reduces needed privileges on my laptop... I trust the phone less than my laptop, so I would rather give my laptop access to the phone than my phone access to my laptop. I dislike this idea because the phone uses 5 watts while charging, and I would prefer to charge it from a household outlet to reduce load on the laptop. The second option is to run rsync's deamon on my laptop, and rsync from the phone via an ifup script that checks the SSID. This works nice because I can charge the phone from an outlet, and do the rsync wirelessly. This is harder to secure though, because I would want the rsync client to have no other access to my laptop. Am I missing other considerations? Which of these two options is better? There is an rsync client app in available for download. I have used it to sync to OBSD for over a year without a problem.
Re: tmux: create window failed (too many open files)
ok, I found why I have some 'null' descriptors... it nears the same case that
with 'tty' descriptors.
I have a custom script (again) for X11 locking, that first destroy kerberos
tickets. And I use tmux show-environment for get KRB5CCNAME environment
variable that I used in the tmux session.
As the script is run by cwm, the input descriptor should be /dev/null.
The patch resolvs all the problem.
For simple test, this command could be used:
$ tmux info /dev/null
This will dup the descriptor in the tmux server, and it will not close it. So
after some time, too many descriptors are opened...
Thanks again.
