[gentoo-user] sshfs issue

[gentoo-user] sshfs issue

[ionut cucu]

I'm running sshfs very often and I've noticed the following issue:
whenever the hub/swich(what ever is that keeping my lan together)
suddenly stops working while I'm using sshfs my computer crashes, or if
I;m lucky enough I get to do an umount before everything falls. Is
there any way to prevent this?
Also since this is a lan is there a null encryption algorithm I could
use to speed things up a bit? Or lower the CPU usage?
Thanks!

Yeah well it's a campus *(1) switch, the campus's *(2) lan, the
campus's *(3) gateway....so on so forth till the A class IP so I can do
nothing about it

Note *(1) to *(2) are ugly words and shouldn't be used around children

You could try telling (asking nicely ;) ) the campus  tech guys to get
their  act together.   It seems,  from what you have said,  that you are
at their mercy.  :(


Be lucky,

Neil

Hmmm no help....

How about this?

http://fuse.sourceforge.net/wiki/index.php/SshfsFaq

Has a section concerning "locking up"...

Also... how about reporting a bug to the developer?
Send bug reports to  fuse-sshfs@lists.sourceforge.net. 


I just glossed over the documentation and saw no mention of a null encryption 
engine. If you are willing to use no encryption... maybe you should try 
another transport protocol... NFS works well.

Also sshfs runs via the FUSE architecture.... Not well know for performance, 
more for "as a means to an end" and it runs slow too.

Cheers.

Are you sure the switch/hub/router is failing?


With any remote connection such as smb/nfs/sshfs, if the target becomes
unavailable for some reason such as lag or a bad route from Point A to
Point B then that terminal window will hang till point B is reachable.

Ha! I was blaming MSWindows for causing the PC to hang whenever I was trying 
to connect to the office file server (through a VPN session).  My reasoning 
went that I shouldn't lose the whole machine for 10 minutes, while waiting 
for an error that it couldn't authenticate me on the domain controller.  I 
blamed the OS for being stupid of course (not withstanding the outsourced 
tech support who can't fix it).  In the sense that neither Linux, nor Gentoo 
constitutes a stupid OS, I think this is a bug.  Fine for the 
application/terminal to crash, but not the whole machine.
