Description Alok Sharma 2022-11-07 13:52:00 UTC

Description of problem:

ypxfrd is not using a static port as configured in /etc/sysconfig/network .

Version-Release number of selected component (if applicable):
ypserv-4.1-1.el8.x86_64
RHEL8.6

How reproducible:

Steps to Reproduce:

- From my testbox:
=======
1. Configure NIS server on RHEL8.6 machine

2. Add below in "/etc/sysconfig/network"
-----------
# Created by anaconda
NISDOMAIN = rh8nis.local  #<== change NIS domain a per the environment
YPSERV_ARGS="-p 834"
YPXFRD_ARGS="-p 835"   
----------

Actual results:

 ypxfrd bound to some other port but not on static configured one.
=======
. # rpcinfo -p 
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper
    100009    1   udp   1010  yppasswdd
    100009    1   tcp   1010  yppasswdd

    100007    2   udp   1017  ypbind
    100007    1   udp   1017  ypbind
    100007    3   tcp   1017  ypbind
    100007    2   tcp   1017  ypbind
    100007    1   tcp   1017  ypbind
    100004    2   udp    834  ypserv
    100004    1   udp    834  ypserv
    100004    2   tcp    834  ypserv
    100004    1   tcp    834  ypserv
 600100069    1   udp    836  fypxfrd #<== different from static configured port
 600100069    1   tcp    836  fypxfrd
=========


Expected results:

ypxfrd should bind to the port 835 as configured in "/etc/sysconfig/network"

Additional info:

- Also, tried with selinux in permissive mode but results were same in RHEL8.6

- I have tried to configure the same on RHEL7.9 to verify and observed that it is working as expected i.e bound to the static configured port:

- From RHEL7.9 testbox

Comment 1 Ondřej Sloup 2022-11-27 17:33:55 UTC

I'm currently working on the issue and could not reproduce it in the 1MT-RHEL-8.6.0-released.
I used this Google Doc guide (https://docs.google.com/document/d/1-qs5sV-boZs0hfti1viQlsGo2MI0e0C1BpD_0MMIfzs) for NIS setup with turned off firewall and the ports were successfully changed after configuration.
Can you please provide more info about the issue?

Comment 5 Ondřej Sloup 2023-01-27 14:28:35 UTC

I suppose that the bug is in rpcbind component and needs to be rebased so this bug can be fixed. After updating the rpcbind package to 1.2.6, the bug is resolved.
