[srslte-users] EPC failed to start after changing epc.conf ip address

[魏宏修]

Hi all,

Recently l've been trying to use srsEPC with own mme_bind_addr and gtpu
_bind_addr.
But I haven't been able to make it work at all.

like this,
eNBs and srsEPC on separate machines
<http://docs.srslte.com/en/latest/srsepc/source/2_epc_getstarted.html#enbs-and-srsepc-on-separate-machines>

By default, srsEPC is configured to run with srsENB on the same machine.
When running srsEPC with an eNB on a separate machine, all that is
necessary to configure is the mme_bind_addr and the gtpu_bind_addr.

The MME bind address will specify where the MME will listen for eNB S1AP
connections. The GTP-U bind address should be the same as the MME bind
address, unless you want to run the user-plane on a different sub-net then
the S1AP connection.

So if you want to listen to eNB on the interface with IP *10.0.1.10*, you
can do:

sudo srsepc --mme.mme_bind_addr 10.0.1.10 --spgw.gtpu_bind_addr 10.0.1.10

The first time I use the original mme_bind_addr(127.0.1.100) and gtpu
_bind_addr ip address( 127.0.1.100) :

Built in Release mode using commit 8c16bca on branch master.


---  Software Radio Systems EPC  ---

Reading configuration file epc.conf.example...
HSS Initialized.
MME S11 Initialized
MME GTP-C Initialized
MME Initialized. MCC: 0xf208, MNC: 0xff93
SPGW GTP-U Initialized.
SPGW S11 Initialized.
SP-GW Initialized.

But when I started EPC after changing the IP address, I encountered some
problems :

Built in Release mode using commit 8c16bca on branch master.


---  Software Radio Systems EPC  ---

Reading configuration file epc.conf.example...
HSS Initialized.
Error binding SCTP socket
MME S11 Initialized
MME GTP-C Initialized
MME Initialized. MCC: 0xf208, MNC: 0xff93
Could not initialize the S1-U interface.
Could not initialize the SPGW's GTP-U.
Error initializing SP-GW

How can I solve this problem?
