I set up the Electrum client - not the server as shown at http://docs.electrum.org/en/latest/merchant.html

I am using Websocket support via perl socket support (from https://centos.pkgs.org/7/epel-x86_64/perl-Protocol-WebSocket-0.18-1.el7.noarch.rpm.html )  as well as the Simple Websocket Server from the above page

Electrum is an rpm installed on CentOS 7 as electrum.noarch  (x86_64) 2.9.0-1.fc26 from  https://www.rpmfind.net/linux/RPM/fedora/updates/testing/26/x86_64/e/electrum-2.9.0-1.fc26.noarch.html

I am running it command line from a shell

I opened ports 7777 and 9999 and verified they are open with the => firewall-cmd --zone=public --list-all <=  command which returns

public
  target: default
  icmp-block-inversion: no

  rich rules:

Electrum is not listening on them

netstat -anp | grep 7777
netstat -anp | grep 9999

returns nothing

A curl call - yields "connection refused"

electrum daemon status

returns a connected status to a server and a getbalance command returns the balance and all other commands relevant work command line

Does anyone know how to get it to listen

[SOLVED]

It does not "listen" but after an upgrade to 2.9.3 (via Rawhide rpmfind) and an install of python-jsonrpclib.noarch => the JSON-RPC v2.0 client library for Python; and the PyQt4-webkit.x86_64 0:4.10.1-2.el7  => which installed 31 dependencies => and the python2-pip-8.1.2-5.el7.noarch.rpm it works.

electrum addrequest .14 -m "this is a test" returns
{
    "URI": "bitcoin:1GHHojoC4Ai1SPMN3YoNzemLNaaj2XFHKc?amount=0.14&r=https://electrum.org//r/req/6/a/6a32d881c0/6a32d881c0",
    "address": "1GHHojoC4Ai1SPMN3YoNzemLNaaj2XFHKc",
    "amount": 14000000,
    "amount (BTC)": "0.14",
    "exp": null,
    "id": "6a32d881c0",
    "index_url": "https://electrum.org//r/index.html?id=6a32d881c0",
    "memo": "this is a test",
    "request_url": "https://electrum.org//r/req/6/a/6a32d881c0/6a32d881c0",
    "status": "Pending",
    "time": 1502814157,
    "websocket_port": 9999,
    "websocket_server": "localhost"

showing the websocket port and server name above last two lines

and a curl call works under JSONRPC yielding as example below

curl --data-binary '{"id":"curltext","method":"getbalance","params":[]}' http://0.0.0.0:7777
{"jsonrpc": "2.0", "result": {"confirmed": "0"}, "id": "curltext"}[root@main ~]#

BUT . . .  neither port shows in rpcinfo or netstat
