[resolv_gethostbyname_done] (0x0040): querying hosts database failed [5]: Input/output error
Hi,
I joined a Ubuntu 20.04 server to a Windows domain, but I am stuck with the following errors in the /var/log/sssd_domain.log file: (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [resolv_gethostbyname_done] (0x0040): querying hosts database failed [5]: Input/output error (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [nsupdate_get_addrs_done] (0x0040): Could not resolve address for this machine, error [5]: Input/output error, resolver returned: [11]: Could not contact DNS servers (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [nsupdate_get_addrs_done] (0x0040): nsupdate_get_addrs_done failed: [5]: [Input/output error] (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [sdap_dyndns_dns_addrs_done] (0x0040): Could not receive list of current addresses [5]: Input/output error (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [ad_dyndns_sdap_update_done] (0x0040): Dynamic DNS update failed [5]: Input/output error (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [be_ptask_done] (0x0040): Task [Dyndns update]: failed with [5]: Input/output error (Tue Apr 13 15:07:38 2021) [sssd[be[my_domain]]] [sdap_sudo_load_sudoers_done] (0x0040): Received 0 sudo rules
I checked the outputs of 'hostname' and 'hostname --fqdn' and they are correct. 'nslookup' resolves correctly the name of any other Windows server within the domain.

Hi,
the sequence above is part of the dynamic DNS update where SSSD tries to figure out if there are already DNS entries for the host. Can you send a bit more log context, especially what happens before?
Maybe there is a timeout, by default SSSD waits 3s for a reply.
bye, Sumit
