Recommended Posts

can not ping as user,  pinging as root works.

kernel 4.19.62

tried..

ping 127.0.0.1

ping: socket: operation not permitted

ping 1

ping: socket: operation not permitted

...

as root:

/sbin/getcap /bin/ping

nothing set

 

to fix it

as root:

chmod u+s /bin/ping

pinging as user works.

working on getting data back.  The device  is not online because too many external firewalls are in the way. so everything needs to be hand copied.

How to reproduce.

MY mistake, it is a R1 not lite

image is

Armbian_5.90_Orangepi-r1_Debian-buster_next_4.19.57.img

Date of file is July5at 15:33

 

Flash to SD.

monut  as loop.

 

/etc/armbian.txt

armbain5.90

kernel 4.19.57

 

ls -l /bin/ping

-rwxr-xr-x 1 root root 47704 Aug  3  2018 /bin/ping

 

Boot image in a r1

(no internet access)

configure root

configure user

login as root

ls -l /bin/ping

-rwxr-xr-x 1 root root 47704 Aug  3  2018 /bin/ping

can ping as root.

 

----

because of no internet access (enterprise network) i cant use armbian-config

create file in lan /etc/network/interfaces.d

  auto eth0

  iface eth0 inet static

  address 192.168.5.250

  network 192.168.5.0

  netmask 255.255.255.0

  gateway 192.168.5.100

 

--bring it up

 ifup eth0 ... no errors

as root can ping debian.org (wierd did not touch resolv.conf)

maybe it would be good to redo this image or DEB package that provide "ping" ...


This is one of those small Buster bugs? ... but if this ping permission problem is here, the problem is probably elsewhere as well? On the download we have bug fixed version 5.91 ...

https://dl.armbian.com/nanopi-r1/archive/

where some other bugs were addressed. Perhaps this was also fixed?
