Hi Christian, Turns out that was left-over test code in rtems_init.c. I commented them out and all is now well. I believe the latest version has them removed. Pete.

But I would expect that your application creates a /dev/dhcpcd.conf somewhere. You can add the "quiet" option to that file: https://urldefense.com/v3/__https://www.freebsd.org/cgi/man.cgi?query=dhcpcd.conf&apropos=0&sektion=0&manpath=FreeBSD*13.0-RELEASE*and*Ports&arch=default&format=html__;Kysr!!P4SdNyxKAPE!XPuMFkMEYBezuIigrxyh13AlgkwIGuLGASXR88ZX4xai51nloC0B_Qsw5x2dgZw$ (Note: The man page is a bit newer than our dhcpcd. But the quiet should be the same.) Alternatively there should be a call to rtems_dhcpcd_start() somewhere (maybe hidden in another call). That function allows an rtems_dhcpcd_config structure pointer as an argument. That structure has an argc and argv. Without testing: I think you could pass a "-q" or a "--quiet" in these to silence dhcpcd. Note that the first field in argv has to be the program name. So you would have to use something like const char *argv[] = {"dhcpcd", "-q", NULL}; int argc = RTEMS_BSD_ARGC(argv); Best regards Christian On 19/07/2021 18:02, Siddons, David wrote: > Hi Heinz, > That statement is in there, in my setup at line 997, but I still get > this every few minutes: > > ***** Primary Network interface : cpsw0 ***** > all out ---> interface = cpsw0 > all out ---> reason = RENEW > all out ---> pid = 1 > all out ---> ifmetric = 201 > all out ---> ifwireless = 0 > all out ---> ifflags = 4294936643 > all out ---> ifmtu = 1500 > all out ---> interface_order = cpsw0 > all out ---> if_up = true > all out ---> if_down = false > all out ---> old_ip_address = 172.16.0.215 > all out ---> old_subnet_cidr = 16 > all out ---> old_network_number = 172.16.0.0 > all out ---> old_subnet_mask = 255.255.0.0 > all out ---> old_broadcast_address = 172.16.255.255 > all out ---> old_dhcp_lease_time = 600 > all out ---> old_dhcp_message_type = 5 > all out ---> old_dhcp_server_identifier = 172.16.0.201 > all out ---> new_ip_address = 172.16.0.215 > all out ---> new_subnet_cidr = 16 > all out ---> new_network_number = 172.16.0.0 > all out ---> new_subnet_mask = 255.255.0.0 > all out ---> new_broadcast_address = 172.16.255.255 > all out ---> new_dhcp_lease_time = 600 > all out ---> new_dhcp_message_type = 5 > all out ---> new_dhcp_server_identifier = 172.16.0.201 > > BTW, this is EPICS 7.0.6 > Pete. > > > > *From:* Heinz Junkes > *Sent:* Monday, July 19, 2021 11:42 AM > *To:* Siddons, David > *Cc:* rtems-us...@rtems.org > *Subject:* Re: suppressing DHCP messages > > FYI, > Pete is a EPICS - User… > > Hello Pete, > in modules/libcom/RTEMS/posix/rtems_init.c in > line 1008 (before sc = rtems_bsd_initialize();) there is a / should be a > line with > rtems_bsd_set_vprintf_handler(rtems_bsd_vprintf_handler_mute); > > That should suppress all output from the network intitialization? > Translated with > https://urldefense.com/v3/__http://www.DeepL.com/Translator__;!!P4SdNyxKAPE!XPuMFkMEYBezuIigrxyh13AlgkwIGuLGASXR88ZX4xai51nloC0B_Qsw905eIOM$ > <https://urldefense.com/v3/__http://www.DeepL.com/Translator__;!!P4SdNyxKAPE!XPuMFkMEYBezuIigrxyh13AlgkwIGuLGASXR88ZX4xai51nloC0B_Qsw905eIOM$ > > (free version) > > Gruss Heinz > > ------------------------------------------------------------------------------ > Fritz-Haber-Institut | Phone: (+49 30) 8413-4270 > Heinz Junkes | Fax (G3+G4): (+49 30) 8413-5900 > Faradayweg 4-6 | VC: 102220181...@bjn.vc > D - 14195 Berlin | E-Mail: jun...@fhi-berlin.mpg.de > ------------------------------------------------------------------------------ > >> On 19.
