The auto-installation process (autod) received the indicated error when it tried to send data on a socket.
The AUTOD_SEND_FAILURE message is logged each time the autod process fails to send data on a connection socket.
When the autod process cannot send data, it logs the action into the syslog. Below are some examples of the message:
AUTOD_SEND_FAILURE: can't send on socket: No route to host
autod: AUTOD_SEND_FAILURE: Unable to send on socket: No route to host
autod: AUTOD_SEND_FAILURE: Unable to send on socket: No such file or directory
The cause for such a notification is that the TCP connection is not able to send data out. This could be due to software or hardware issues.
Review the output of ‘show log messages’ to see if there are other events or errors being reported that may relate to the connection that autod is using.
This log message has been reported on EX and SRX devices. The auto-installation feature is not available in Junos 9.5.
