So I'm on my Powerbook (10.4.1), and SSH across the good old domestic
WLAN to my G5 (Also 10.4.1). I get behavior like this:
[mightygorilla:~] tas% ssh yobgorgle
Password:
Welcome to Darwin!
[yobgorgle:~] tas% ls
tcsh: Out of memory.
Connection to yobgorgle closed.
[mightygorilla:~] tas%
Some shell commands do succeed, but most fail identically to this
example with ls.
Bizarre thing #1: the G5 named "Yobgorgle" had roughly 2GB free RAM
at the time of this event. Physical memory certainly isn't a
problem. The only justification for the error in question is if some
piece of code tried to allocate more address space than the kernel
was willing to give a single process.
Bizarre thing #2: So, "yobgorgle" is really "yobgorgle.local" since I
have "local" in my search domains list. In other words, it's a
Ren^h^h^h Bonjour name. On a whim, I decided to SSH to the actual IP
address:
Bizarre thing #3: Everything seems to work normally when I SSH in the
opposite direction, regardless of whether I use the Bonjour name or
the IP address of the PowerBook. The only remotely relevant
difference in configuration which I can think of is that the
PowerBook gets its IP address via DHCP whereas the G5 has a static IP.
My brain hurts. Why should the shell (or alternately the programs
it's invoking) care how the network name lookup for setup of the SSH
session it's communicating through took place? And how can this
behavior happen on one machine and not the other?
Nothing appears in system.log or /cores, by the way.
Anybody have any suggestions before I file a bug?
