# Packet capture configuration
#
# MAC-layer packets are captured to file a the compact format decoded
# by the Wireshark. For decoding, use the UDP dissector and the UDP
# heuristic dissection. Edit the preferences (Edit > Preferences >
# Protocols > DLT_USER) for DLT_USER to add an entry for DLT=149 with
# Protocol=udp. Further, enable the heuristic dissection in UDP under:
# Analyze > Enabled Protocols > MAC-LTE > mac_lte_udp and MAC-NR > mac_nr_udp
# For more information see: https://wiki.wireshark.org/MAC-LTE
# Configuring this Wireshark preferences is needed for decoding the MAC PCAP
# files as well as for the live network capture option.
#
# Please note that this setting will by default only capture MAC
# frames on dedicated channels, and not SIB. You have to build with
# WRITE_SIB_PCAP enabled in srsenb/src/stack/mac/mac.cc if you want
# SIB to be part of the MAC pcap file.
#
# S1AP Packets are captured to file in the compact format decoded by
# the Wireshark s1ap dissector and with DLT 150.
# To use the dissector, edit the preferences for DLT_USER to
# add an entry with DLT=150, Payload Protocol=s1ap.
#
# mac_enable: Enable MAC layer packet captures (true/false)
# mac_filename: File path to use for packet captures
# s1ap_enable: Enable or disable the PCAP.

@andrepuschmann, sorry to disturb you. The problem remains unresolved, I will be very grateful for the answer
Usually the issue comes from insufficient rights to set scheduler to RT. Since you're running with sudo you should have the rights though. I don't think it's an srsRAN issue though.
I can start srsenb when I use normal user rights, but I will get the same error as you. When I start srsenb with the root user, it prompt "error while loading shared libraries: libsrsran_rf.so.0". I solved it in the following ways. Maybe you can try.
- Run on the command line terminal:“find / -name libsrsran_rf.so.0”. I found it under my project folder and "/ usr/local/lib" folder.
- Run on the command line terminal:"vi /etc/ld.so.conf", and add "/ usr/local/lib" under "include ld.so.conf.d/*.conf".
- After save it, run on the command line terminal:"sudo /sbin/ldconfig -v", "sudo ldconfig" It works for me.
