To resolve "Sync Updates" error when using UMDS on vCenter where proxy is enabled.
When vCenter is configured with a proxy server, the Sync Updates module tries to download updates from UMDS via the proxy. In environments where vCenter does not need to go through proxy to connect to the UMDS server and proxy is being used only for outbound connections, this task would fail as there is no route from the proxy to UMDS server.
We can workaround this issue by configuring the "no_proxy" variable to include the hostname / IP address of the UMDS server. Edit the Proxy configuration file on vCenter to include the hostname/IP address of the UMDS server ( in this example umdsserver.com is the name of UMDS server ):Navigate to the location of the proxy file cd /etc/sysconfig/Default output of proxy file# Enable a generation of the proxy settings to the profile.# This setting allows to turn the proxy on and off while# preserving the particular proxy setup.#PROXY_ENABLED="yes"# Some programs (e.g. wget) support proxies, if set in# the environment.# Example: HTTP_PROXY="http://proxy.provider.de:3128/"HTTP_PROXY=""# Example: HTTPS_PROXY="https://proxy.provider.de:3128/"HTTPS_PROXY=""# Example: FTP_PROXY="http://proxy.provider.de:3128/"FTP_PROXY=""# Example: GOPHER_PROXY="http://proxy.provider.de:3128/"GOPHER_PROXY=""# Example: SOCKS_PROXY="socks://proxy.example.com:8080"SOCKS_PROXY=""# Example: SOCKS5_SERVER="office-proxy.example.com:8881"SOCKS5_SERVER=""# Example: NO_PROXY="www.me.de, do.main, localhost"NO_PROXY="localhost, 127.0.0.1" Use VI editor to add the UMDS server IP/FQDN under "NO_PROXY" # Enable a generation of the proxy settings to the profile.# This setting allows to turn the proxy on and off while# preserving the particular proxy setup.#PROXY_ENABLED="yes"# Some programs (e.g. wget) support proxies, if set in# the environment.# Example: HTTP_PROXY="http://proxy.provider.de:3128/"HTTP_PROXY="http://proxy.provider.de:3128"# Example: HTTPS_PROXY="https://proxy.provider.de:3128/"HTTPS_PROXY=""# Example: FTP_PROXY="http://proxy.provider.de:3128/"FTP_PROXY=""# Example: GOPHER_PROXY="http://proxy.provider.de:3128/"GOPHER_PROXY=""# Example: SOCKS_PROXY="socks://proxy.example.com:8080"SOCKS_PROXY=""# Example: SOCKS5_SERVER="office-proxy.example.com:8881"SOCKS5_SERVER=""# Example: NO_PROXY="www.me.de, do.main, localhost"NO_PROXY="localhost, 127.0.0.1, umdsserver.com" Save the file and exit :wq!
