Public bug reported: I am having issues loading certain websites such as linkedin.com and portions of google sites including images.google.com, hotmail.com login, etc. After looking through some logs and such I've determined that resolved is not properly following CNAMEs to an IP address. Querying the DNS server on my network directly for the info works fine. Loading the sites from other computers on the network works fine.
In the #systemd IRC channel I was directed to the following two issues: https://github.com/systemd/systemd/pull/18892 https://github.com/systemd/systemd/pull/19009 System info: Ubuntu 20.10 ii systemd 246.6-1ubuntu1.2 amd64 system and service manager ii linux-generic 5.8.0.48.53 amd64 Complete Generic Linux kernel and headers Example: [11:06:00]<root@castle:/var/log> host static-exp1.licdn.com Host static-exp1.licdn.com not found: 2(SERVFAIL) [11:06:17]<root@castle:/var/log> resolvectl status Global LLMNR setting: no MulticastDNS setting: no DNSOverTLS setting: no DNSSEC setting: no DNSSEC supported: no DNS Domain: rhos.bigfiber.net bigfiber.net Link 2 (enp6s0) Current Scopes: none DefaultRoute setting: no LLMNR setting: yes MulticastDNS setting: no DNSOverTLS setting: no DNSSEC setting: no DNSSEC supported: no Link 3 (enp4s0f0) Current Scopes: DNS DefaultRoute setting: yes LLMNR setting: yes MulticastDNS setting: no DNSOverTLS setting: no DNSSEC setting: no DNSSEC supported: no Current DNS Server: 10.18.1.1 DNS Servers: 10.18.1.1 DNS Domain: ~. rhos.bigfiber.net bigfiber.net Link 4 (enp4s0f1) Current Scopes: none DefaultRoute setting: no LLMNR setting: yes MulticastDNS setting: no DNSOverTLS setting: no DNSSEC setting: no DNSSEC supported: no [11:06:26]<root@castle:/var/log> host static-exp1.licdn.com 10.18.1.1 Using domain server: Name: 10.18.1.1 Address: 10.18.1.1#53 Aliases: static-exp1.licdn.com is an alias for 2-01-2c3e-003d.cdx.cedexis.net. 2-01-2c3e-003d.cdx.cedexis.net is an alias for li-prod-static.azureedge.net. li-prod-static.azureedge.net is an alias for li-prod-static.afd.azureedge.net. li-prod-static.afd.azureedge.net is an alias for star-azureedge-prod.trafficmanager.net. star-azureedge-prod.trafficmanager.net is an alias for dual.t-0009.t-msedge.net. dual.t-0009.t-msedge.net is an alias for t-0009.t-msedge.net. t-0009.t-msedge.net is an alias for Edge-Prod-WSTr3.ctrl.t-0009.t-msedge.net.
