using ngctl and 'hole' nodes in this configuration I cannot make this happen.
here's the sequence I used:
+ mkpeer hole aaa aaa
+ name aaa near
+ mkpeer hole bbb bbb
+ name bbb far
+ connect near: far: ccc ccc
+ connect lnc0: far: orphans ddd
+ list
There are 4 total nodes:
Name: far Type: hole ID: 00000008 Num hooks: 3
Name: near Type: hole ID: 00000007 Num hooks: 2
Name: ngctl192 Type: socket ID: 00000006 Num hooks: 2
Name: lnc0 Type: ether ID: 00000005 Num hooks: 1
+ show far:
Name: far Type: hole ID: 00000008 Num hooks: 3
Local hook Peer name Peer type Peer ID Peer hook
---------- --------- --------- ------- ---------
ddd lnc0 ether 00000005 orphans
ccc near hole 00000007 ccc
bbb ngctl192 socket 00000006 bbb
+ shutdown near:
+ shutdown far:
+ list
There are 2 total nodes:
Name: lnc0 Type: ether ID: 00000009 Num hooks: 0
Name: ngctl192 Type: socket ID: 00000006 Num hooks: 0
+
no messages were printed on the console...
can you repeat this sequence using your nodes and see if you get an error when
it is done by hand (slowely?).
I'll try it again from a script using ngctl -f
[later]
no, it still doesn't complain..
can you try this: ( I assume atm is permanent like lnc0: )
cat > tmp/it <<DONE
mkpeer hole aaa aaa
name aaa near
mkpeer hole bbb bbb
name bbb far
connect near: far: ccc ccc
connect lnc0: far: orphans ddd
list
show far:
shutdown near:
shutdown far:
list
DONE
ngctl -f /tmp/it
