Yes, but that doesn't mean what you think it means. > root@rhadamanth setantae# ntpdc -c "showpeer ntp2b.mcc.ac.uk" > remote 130.88.200.98, local 62.254.251.122 This is a query for information *about* ntp2b.mcc.ac.uk from your machine, pc3-card3-0-cust122.cdf.cable.ntl.com. The host on the command line is the host to query. Compare the output of: ntpdc -c peers ntp2b.mcc.ac.uk and: ntpdc -c "peers ntp2b.mcc.ac.uk" When you said: > root@rhadamanth setantae# ntpdc -c showpeer ntp2b.mcc.ac.uk ntpdc correctly interepreted that as a request to query ntp2b.mcc.ac.uk for some information, but then determined that the command you gave it (`showpeer') was not properly formed. -GAWollman State Changed From-To: open->closed Pilot error. |
Not sure if this is a documentation bug or a software bug. The manpage for ntpdc states : SYNOPSIS ntpdc [-ilnps] [-c command] [host ...] -c command The command argument is interpreted as an interactive format com- mand and is added to the list of commands to be executed on the specified host(s). Multiple -c options may be given. which indicates that all commands specified should default to the host given on the command line. This does not happen, since the host is not passed to the command to be executed unless quotes are used. Fix: The above _is_ a workaround. However, the documentation suggests that the first method attempted should work.
