Thread: Names of other systems on local network changed!

-

i have 2 computers running ubuntu on local network connected router. router (at 192.168.2.1) sees both systems (as tv set, isn't technology wonderful!) , recognizes them name "jcobban-laptop" , "linux-server". if try use names, example in ping, "unknown host". names used work, stopped working recently.

jcobban@linux-server:~$ ping jcobban-laptop
ping: unknown host jcobban-laptop
jcobban@linux-server:~$ ping 192.168.2.14
ping 192.168.2.14 (192.168.2.14) 56(84) bytes of data.
64 bytes 192.168.2.14: icmp_req=1 ttl=64 time=1.53 ms
...

when ask router tells me jcobban-laptop has ip address 192.168.2.14 assigned dhcp , linux-server has address 192.168.2.103 dhcp. (the tv set has 192.168.2.10 dhcp.)

** server can't find jcobban-laptop: nxdomain

if, following obscure advice in post response, tack ".local" onto name works!

jcobban@linux-server:~$ ping jcobban-laptop.local
ping jcobban-laptop.local (192.168.2.14) 56(84) bytes of data.
64 bytes 37l4247d28-05 (192.168.2.14): icmp_req=1 ttl=64 time=2.70 ms
64 bytes 37l4247d28-05 (192.168.2.14): icmp_req=2 ttl=64 time=0.601 ms
...

presumption microcode in router got changed time, although not recall updating in @ least year.

how to devide a circle into equal parts

how devide circle equal parts reggie,   depending on version, may able use free divide (length) script available here, setting number,   http://park12.wakwak.com/~shp/lc/et/en_aics_script.html   or may (smart guides friends):   1) use polar grid tool right size of circle, 0 concentric dividers , desired number of radial dividers, , ungroup; 2) extend radial dividers; 3) select circle , use scissors tool @ intersections (smart guides intersect ), may need select remaining parts underway.   or may (smart guides friends):   1) create vertical line through top , bottom (or left , right) anchor points line tool; 2) rotate copies @ relevant angles (to half number of cuts division); 3) select circle , use scissors tool @ intersections (smart guides intersect ), may need select remaining parts underway.
