Generic or SSL connection errors¶
Please see Proxy_communication_errors first for SSL or communication errors, which aren't specific to this particular proxy action.
Foreman 1.5.1: Removing a Proxy::DHCP Record which doesn't exist¶
Seen on Foreman 1.5.1, this is bug #6412.
E, [2014-06-20T15:14:54.521280 #1384] ERROR -- : Removing a Proxy::DHCP Record which doesn't exist D, [2014-06-20T15:14:54.521353 #1384] DEBUG -- : /usr/share/foreman-proxy/bin/../lib/proxy/dhcp/subnet.rb:184:in `delete' /usr/share/foreman-proxy/bin/../lib/proxy/dhcp/server/isc.rb:64:in `loadSubnetData'
Note that stack trace contains
loadSubnetData on line 64.
[RestClient::RequestTimeout]: Request Timeout¶
If the DHCP reservation isn't added, see Proxy_communication_errors.
If it is added, the proxy is taking too long to add it, so Foreman is timing out. If you have many subnets configured but only need to manage a few, try setting dhcp_subnets in the proxy configuration to restrict those it loads (available from Foreman 1.5.1):
:dhcp_subnets: [192.168.205.0/255.255.255.128, 192.168.205.128/255.255.255.128]
Issue #5847 tracks this problem.
Using AD DHCP and Windows 2008¶
Seen on Windows 2008 R2. In proxy.log, it logs:
I, [2014-05-30T09:06:23.096367 #2620] INFO -- : Vendor class not found E, [2014-05-30T09:06:23.096367 #2620] ERROR -- : Netsh failed: Changed the current scope context to 172.28.4.0 scope. The specified option does not exist.
This is bug #5995. To workaround it, remove the option 60 added here: https://github.com/theforeman/smart-proxy/commit/296617a
