up vote 0 down vote favorite running ubuntu 16. installed apcupsd UPS is not yet connected. just installing software. tried running this command: apcaccess status got: Error contacting apcupsd @ 127.0.0.1:3551: Connection refused checked community fixes; they are all in place. could this be because I don't have the UPS USB cable connect yet? Any idea how to troubleshoot this? Steve networking share | improve this question asked Nov 27 at 16:03 1ProTech 1 1 ...

up vote 0 down vote favorite Show that if a simple graph with at least two vertices is connected and has no cut vertices, then any two vertices lie on a cycle and any two edges lie on a cycle. I assume if $G$ is connected and has no cut vertices, then if we remove any vertex from $G$ , the remaining graph is still connected. And does that automatically mean any two vertices lie on a cycle and any two edges lie on a cycle? graph-theory share | cite | improve this question edited Nov 19 at 18:27 asked Nov 19 at 15:20 ...
