Cannot access Oscam webinterface

It could also be that you have several Oscam configuration files "oscam.conf" (configuration directories), from which Oscam selects the wrong configuration and always stays on the port that contains the next configuration file.

Usually, many service technicians for set-top boxes, set 83 port to softcam, but this is not recommended because these low port values are usually used as system ports. They are usually strictly secured - on many active network elements.

Try to find all "oscam.conf" files in the file-system of the set-top box:

find / -type f -iname "oscam.conf"

If this does not help, try to verify whether Oscam is running at all and what its startup command-line looks like.

It can be verified in several ways, but it depends on the distribution of your Enigma2, which Linux it uses. In some Linuxes, the same commands do not work (it is limited by a different version of the command or even by using BusyBox). So try something like this (copy as CTRL + C / V, the whole script, into the linux-shell and run it):

OSCAM_LOCAL_PATH=$(find /usr/bin -iname 'oscam*' | head -n 1)
OSCAM_BIN_FNAME=${OSCAM_LOCAL_PATH##*/}
if ps --version 2>&1 | grep -q -i "busybox"; then
    OSCAM_CMD=$(ps | grep $OSCAM_BIN_FNAME | grep -v grep | head -n 1 | grep -o '/.*$')
else
    OSCAM_CMD=$(ps -f --no-headers -C $OSCAM_BIN_FNAME | head -n 1 | grep -o '/.*$')
fi
echo "${OSCAM_CMD}"

The "top" command can also help display the Oscam full command-line. However, this "top" command may not work the same on every set-top box (BusyBox VS full Linux command):

top -c

Then find oscam in the list and see what startup parameters it has (configuration directory).

There... in this startup command-line for Oscam, you should see, a modified path to the configuration directory if there is no default path.

As a last thing, it's a good idea to check if the ports on the set-top box are open and if so, for which services:

netstat -tulpn | grep cam
