Getting slow speeds in sshfs

When copying files from a sshfs mount to the local drive, my speeds are way
slower than if i were to use scp or sftp.

The versions I'm using of sshfs and fuse is

SSHFS version 2.5

FUSE library version: 2.9.2

fusermount version: 2.9.2

using FUSE kernel interface version 7.19

I'm also using the hpn patched ssh with version

OpenSSH_6.6.1p1-hpn14v5 Ubuntu-5hpn14v5~wrouesnel~trusty2, OpenSSL 1.0.1f 6
Jan 2014

located from

https://launchpad.net/~w-rouesnel/+archive/ubuntu/openssh-hpn

I've tweaked my TCP window sizes and options with these below in
/etc/sysctl.conf

net.core.wmem_max=25165824

net.core.rmem_max=25165824

net.ipv4.tcp_rmem= 20480 174760 25165824

issue connecting remote disks - help on bug - NoMachine

Hello,
my name is Linda Burchi, I am a project manager in Nomachine.com.
We currently have one trouble report which could be related to a bug in 
your code.
https://www.nomachine.com/TR02M05006
We are using sshfs (2.4 version) with fuse (2.9.0 version) to connect 
remote disks. We noticed some problems while refreshing content of 
connected disks. When we connect a disk from a computer A (linux 64bit) 
to a computer B (linux 64bit) and  we add some files to the remotely 
connected disk on computer A, this files are not visible in 
terminal/file managers on computer B. Refreshing content in file manager 
doesn't solve this problem. We tried different sshfs options when 
connecting disks and none of them solves our problem.
I put in copy Michal Czyrski, a developer who is working on this TR, 
feel free to contact him if you need further information and details.
Please take into account that we have a testing team and it is not a 
problem for us to test a patch and check if it fixes the bug.
Any feedback and comments would be highly appreciated.
Best regards,
Linda Burchi

Problems establishing connection after password prompt

Hey,

I'm trying to mount a remote folder via sshfs on arch with current software.

User on the server side is different from local user.

After entering sshfs -C userserver <at> server:serverfolder clientfolder I
get the password promptfor userserver. Then nothing more happens, i.e.
the shell does not return. So after help from the arch forums I tried
again with debug informations (-d and -o LOGLEVEL=DEBUG3) turned on .
Unfortunately this does not solve my problem, since for me there is no
useful information. Apparently at some stage after login prompt it gets
stuck

|Password:

sshfs, hardlinks and use_ino

Hi,

I think I've found a bug in SSHFS:

- I can create hardlinks over SSHFS, but by default, stat then reports
  different inodes for the original file and the hardlink!
  (This behavior is very strange by itself, and I would consider it a
  bug by itself, since it breaks the definition of a hardlink.)

- "-o use_ino" should fix this, but when I try to mount with this
  option, the mount seems to fail silently (no error-message, mounted
  according to "mount", but there are no files).

This should be fixed, so that either hardlinks work correctly (and stat
reports the same inode-numbers for hardlinks), or that sshfs fails when
trying to create a hardlink.

Note: This e.g. means that you cannot use mutt with maildirs over sshfs
      anymore, since mutt tries to hardlink a file and then compares the
      inodes; and if they don't match, mutt will hang/loop and create
      thousands (or more) of hardlinks until mutt is killed.
      (Related Debian-bug-number: #778801)

Tested with SSHFS on Debian (both Wheezy/stable and testing):
- SSHFS version 2.4
  FUSE library version: 2.9.0
  fusermount version: 2.9.0
  using FUSE kernel interface version 7.18
- SSHFS version 2.5
  FUSE library version: 2.9.3

gnome-keyring daemon fails on SSHFS

Hi, is it possible for this bug to get solved from the SSHFS side instead
of the gnome-keyring side?
https://bugzilla.gnome.org/show_bug.cgi?id=730587

I don't know if the GNOME developers are willing to fix it in gnome-keyring
if they consider it a bug in SSHFS, but if it is a limitation in SFTP and
can't be fixed in SSHFS, we'll have a better chance of convincing them...

Thank you!

[Bug] Mount freezes on specific mount point

Hi there,

since two days, I have been experiencing a very strange bug with sshfs. It seems to be related to an
openssl/openssh update (since it worked before and that's the only thing which changed). However with
downgrading I was not able to isolate the issue, neither on Gentoo nor Arch, and had the issue on both systems.

I don't know if that's related, but I have in my .ssh/config:
Host sks
  HostName saunaserver
  ServerAliveInterval 10

saunaserver is a hosts entry which maps to a LAN IP. 

What I observe:
bzk <at> silencio ~ $ mkdir mnt/
bzk <at> silencio ~ $ sshfs sks:/mnt/raid mnt/
bzk <at> silencio ~ $ ls mnt/
data  literature  lost+found  music  rcs  roms  share  software  torrents  video
bzk <at> silencio ~ $ fusermount -u mnt/
bzk <at> silencio ~ $ mkdir sks
bzk <at> silencio ~ $ sshfs sks:/mnt/raid sks/
bzk <at> silencio ~ $ ls sks
data  literature  lost+found  music  rcs  roms  share  software  torrents  video
bzk <at> silencio ~ $ fusermount -u sks

Hisenbug

Hey guys

I’m running a macbook pro

OSX: 10.9.5
2.6Hz i5
8GB ram (1600Mhz DDR3)

SSHFS version 2.5 (OSXFUSE SSHFS 2.5.0)
OSXFUSE library version: FUSE 2.7.3 / OSXFUSE 2.7.1

When I try and run 

	sshfs user <at> host ~/amount/point -o allow_other,reconnect,volname=AName 

from within a launchctl launch agent I get no error but no mounted drive either.

If I replace the command with

	sshfs user <at> host ~/amount/point -o debug,allow_other,reconnect,volname=AName

again from within a launchctl launch agent I get all of the debugging output to stdout and the remote fs is
mounted at ‘~/amount/point’

This seems like pretty sketchy behaviour, anyone have any ideas why this might be the case?

Regards,
Jasper

sshfs's use of -x can stop X forwarding when ControlMaster is used

Hi,

I just noticed that I did not have DISPLAY set in a login to a host for
which I configure "ForwardX11 yes". This turned out to be because I had an
sshfs mount as my first command in the current session to that host. sshfs
passes -x to ssh, which overrides my config. The connection is reused for
other logins (because I have ControlMaster auto configured for that host),
so I get no X forwarding.

I'm not sure what the best solution is, but how about passing "-o
ControlMaster=no' to ssh, so that it doesn't accidentally reconfigure a
session master?

I'm using sshfs 2.5 as packaged in Ubuntu 14.04.

Very odd problem with sshfs hanging

Hello,

I'm doing some development in the Go language, and I'm trying to 
remotely mount a directory called "gocode" - this is a conventional name.

Running the command:

sshfs -odebug,sshfs_debug,loglevel=debug garcon:/home/johnl/gocode/ 
./gocode/

produces the following output:

SSHFS version 2.4
FUSE library version: 2.9.0
nullpath_ok: 0
nopath: 0
utime_omit_ok: 0
executing <ssh> <-x> <-a> <-oClearAllForwardings=yes> <-ologlevel=debug> 
<-2> <garcon> <-s> <sftp>

and hangs indefinitely. In fact I can't even get another terminal to 
open without dropping down the console as root and killing sshfs with -9.

The odd thing is that this behavior seems to depend on the name of the 
local folder. If I rename the local folder with

mv gocode xgocode

Then the mount works perfectly.
