If traceroute isn't working, ping likely won't be either - blocking ICMP at the edge is common enough. Trying a ping utility that uses UDP (hping) is worth trying too. If you're already dealing with security at the edge that's limiting the aforementioned protocols, it isn't likely that ssh is going to be allowed directly either. Telnet is an option if the host serves up protocols you are aware of - just telnet to the actual socket 'telnet <ip> <port>'. If all else fails, try an nmap (disable the ping) and see what ports are open.

Cheers,

Keith

[OCF_RESKEY_pidfile=string] [OCF_RESKEY_dampen=integer] [OCF_RESKEY_name=string] [OCF_RESKEY_multiplier=integer] [OCF_RESKEY_host_list=string] [OCF_RESKEY_attempts=integer] [OCF_RESKEY_timeout=integer] [OCF_RESKEY_options=string] [OCF_RESKEY_debug=string] ping [start | stop | reload | monitor | meta-data | validate-all] DESCRIPTION
Every time the monitor action is run, this resource agent records (in the CIB) the current number of ping nodes the host can connect to. It is essentially the same as pingd except that it uses the system ping tool to obtain the results. SUPPORTED PARAMETERS
OCF_RESKEY_pidfile = string [/var/run//ping-default] PID file OCF_RESKEY_dampen = integer [5s] Dampening interval The time to wait (dampening) further changes occur OCF_RESKEY_name = string [pingd] Attribute name The name of the attributes to set. This is the name to be used in the constraints. OCF_RESKEY_multiplier = integer [] Value multiplier The number by which to multiply the number of connected ping nodes by OCF_RESKEY_host_list = string [] Host list The list of ping nodes to count. Defaults to all configured ping nodes. Rarely needs to be specified. OCF_RESKEY_attempts = integer [2] no. of ping attempts Number of ping attempts, per host, before declaring it dead OCF_RESKEY_timeout = integer [2] ping timeout in seconds How long, in seconds, to wait before declaring a ping lost OCF_RESKEY_options = string [] Extra Options A catch all for any other options that need to be passed to ping. OCF_RESKEY_debug = string [false] Verbose logging Enables to use default attrd_updater verbose logging on every call. AUTHOR
