I fail to install a new python package, and get this: sudo apt-get install python-requests Reading package lists... Done Building dependency tree Reading state information...

It is a 24/7 system running at a remote location and reboots due to e.g. kernel panics are not really happening. So far only external devices such as 3g sticks has suddenly stopped working and needed a power cycle (yes - with help of GPIO and a MOSFET). A bigger problem has been power outages a few ...

I don't know the concept of a permanent directory - can you give me a hint what this is? Would that eliminate the risk of corrupted ext4/fat file system in case of power outage? I have had pretty bad experience on that with Raspberry Pi...that why I now run on a completely ro file system...much more...

my mount looks like this: /dev/root on / type ext4 (ro,noatime,data=ordered) devtmpfs on /dev type devtmpfs (rw,relatime,size=216108k,nr_inodes=54027,mode=755) tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=44876k,mode=755) tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,siz...

...so again I'll answer myself: It seem as if the variable TMPTIME is not set to 0 (clean at boot) as I assumed - it is not set at all. This probably results in this unwanted behaviour (if I read /etc/init/mounted-tmp.conf correct). I'll now set this in /etc/default/rcS and hope it will do the job (...

Do you know if there is any cronjob/process which remove old files in /tmp?
I am experiencing disappearing files...
Since I have set up a headless system ro file system, I am "misusing" /tmp as ordinary ram disc and would like to keep things there until next reboot.

This was my problem and now it works - thanks for the hint and explanation (which also explains why it worked for me in the past - I had removed ttyAMA0 in cmdline.txt since I needed the serial port for other stuff).

Although I could not get the kernel.panic in sysctl.conf to work (should consider to report this as a bug?), I found a solution which is much better for my particular purpose - use the Raspberry Pi watchdog. $ sudo modprobe bcm2708_wdog $ echo "bcm2708_wdog" | sudo tee -a /etc/modules $ su...

I did both try the sysctl -p and a manual reboot - no difference.
(cat /proc/sys/kernel/panic says 10)
I am running a headless system with a 1000 km away and can only
maintain it a few times/year.
I have had no panics so far but would like a automatic reboot if there would
be glitch causing a crash.

Clarification: It seem to be independent if ro or rw file system - I tried on a rw system and it does not automatically reboot. Since I recall that this has worked with an older Raspian version, I either I have found a fault in Raspian or something in my setup is wrong - any chance someone can try i...

I am running a headless RPi using Raspian with ro file system. Now I want the system to automatically reboot on kernel panic so I have added kernel.panic = 10 to /etc/syscntl.conf and rebooteded to make the setting active. If I now generate a kernel panic by echo c > /proc/sysrq-trigger # as root th...

Sakis3g sometimes need to run certain commands as sudo.
Try to add alwayssudo to your sakis3g config file (/etc/sakis3g.conf)
and then use the /etc/init.d start variant (which I find most elegant solution).

AlterSchwede

To reboot after kernel panic:
Add to /etc/sysctl.conf:

Code: Select all

# reboot at kernel panic (seconds before reboot).
kernel.panic = 5

This matter is now solved (but not sure how to mark it as 'solved' in the thread). I created a file ”/etc/usb_modeswitch.d/E173.conf” ######################################################## # Huawei, newer modems DefaultVendor= 0x12d1 DefaultProduct=0x1446 TargetVendor= 0x12d1 TargetProduct= 0x1436...

(edit:added modem ids) I also use sakis3g and get a connection as soon as the modem i/f for the stick is visible (/dev/ttyUSB0 etc. is created). Go get sakis3g to work the stick must be able to switch to Vendor=12d1 ProdID=1436 (modem mode). At the moment it is stuck on ProdID=1446. The problem is t...

Clarification: The XSStick P14 still behaves relatively OK (works after reboot), but the E173 stick which is supposed to be compatible to RPi not. I created at completely clean system with the latest Raspbian image (2012-12-16) and installing usb-modeswitch - still no success to get E173 to show the...

Now, after an sudo apt-get upgrade, I have the opposite problem: after power on with the stick Huawei E173 already connected, I cannot see the modem modes anymore. usb-devices: T: Bus=01 Lev=03 Prnt=04 Port=01 Cnt=01 Dev#= 5 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 ...

AlterSchwede

Yes,
Now with latest Raspian, I see the modem modes too on the P14 stick (but must do a soft reboot after a power cycle). Good enough! I am also using Sakis3G.

I had similar issues using both powered and passive hubs (and if I recall even without hub but in combination with wlan/wifi stick). The problem disappeared when I booted without (valid for both my wireless and USB) keyboard. I plug in the keyboard when booting is completed. I have no explanation wh...

At least for Rasbian, usb-modeswitch is already is already installed (if I recall right). Therefore, you should pick the Sakis3G binary free version (http://www.sakis3g.org/versions/latest/binary-free/sakis3g.gz). It runs fine on Rasbian. As you stated you might need to install ppp once by: sudo apt...

I have a problem that it seems as umts sticks only works first time if power is switched on when stick is already connected. I have tried with both XS stick P14 and Huawei E173. (Power off, connect the stick, power on works FIRST time). Subsequent power cycles with stick connected does not show mode...
