It's only recently that I wanted to maintain multiple versions of the same file. I notice that when creating the second and subsequent versions of a file, the version is zero length. After creating the subsequent version, the former version length is correct. I've repeated this experiment on two different VMS installations. For example, from Debian Jessie: sshfs chimenej&lt; at &gt;portingalpha: /mnt/hp ======== Copy #1 cp run-all /mnt/hp/ `run-all' -&gt; `/mnt/hp/run-all' ls -lat /mnt/hp/run-all -rw-r----- 1 8519689 130 535 May 12 13:40 /mnt/hp/run-all ======== VMS sees the following $ dir/siz=all run-all*.*;* Directory PTAC$DKA100:[CHIMENEJ] run-all.;1 2/16 Total of 1 file, 2/16 blocks. ======== Copy #2 cp run-all /mnt/hp/ `run-all' -&gt; `/mnt/hp/run-all' ls -lat /mnt/hp/run-all -rw-r----- 1 8519689 130 0 May 12 13:42 /mnt/hp/run-all ======== VMS sees the following $ dir/siz=all run-all*.*;* Directory PTAC$DKA100:[CHIMENEJ] run-all.;2 0/0 run-all.;1 2/16 Total of 2 files, 2/16 blocks. ======== Copy #3 cp run-all /mnt/hp/ `run-all' -&gt; `/mnt/hp/run-all' ls -lat /mnt/hp/run-all -rw-r----- 1 8519689 130 0 May 12 13:46 /mnt/hp/run-all ======== VMS sees the following $ dir/siz=all run-all*.*;* Directory PTAC$DKA100:[CHIMENEJ] run-all.;3 0/0 run-all.;2 2/16 run-all.;1 2/16 fusermount -u /mnt/hp Finally, after a single SFTP PUT session, VMS sees the following: Directory PTAC$DKA100:[CHIMENEJ] run-all.;4 2/16 run-all.;3 0/0 run-all.;2 2/16 run-all.;1 2/16 Total of 4 files, 6/48 blocks. I realize that this might be the way cp handles the copy. The Eclipse -&gt; Export -&gt; Filesystem command gives the same result for 2nd and subsequent copies.

Mount options. In the sshfs general options, mount options (-o opt,[opt...]) documentation, it might be helpful to specify which options are available. Rationale: sshfs rightly does not support all the mount man page's "FILESYSTEM INDEPENDENT MOUNT OPTIONS" and the mount man page does not have a section for sshfs. Thus the user has to guess, reason or experiment to find which mount options are available. For example I found by experiment that noatime is accepted but nodiratime and noiversion are not. 2. Command path completion. It did not work for me within directories under an sshfs mountpoint. For example on typing cd &lt;sshfs mount point&gt;/ then tab and tab, nothing was listed as it is for the usual file systems. If this is normal behaviour it might be helpful to mention it in the man page. Rationale: this is not customary behaviour. Nice for there to be no surprises for the user who has read the documentation. Nice for the user who finds and investigates unusual behaviour to have it confirmed as normal in the documentation.

The weird thing is, it only does this for certain directories, that have been mountpoints in the past, and I can't work around the problem by deleting/recreating the directory either. Neither lsof, fuser or running sshfs with debugging enabled tell anything. The remote logs only say that the client disconnected without sending auth info (as soon as I kill sshfs, until then it just halts). I am really stuck here...

The default is to error on unknown UIDs/GIDs. </pre> Mike Kelly 2013-02-20T15:14:58 http://permalink.gmane.org/gmane.comp.file-systems.fuse.sshfs/1396 <pre> Okay, looks like the problem is that you need to have *all* user and group IDs that might be returned by the server in the uid and gid map files. Otherwise the translation will fail and return EPERM. Thanks, Miklos ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.

I understand your workaround - reading the manual again (here on Debian), even though its standard usage for me to specify an IdentityFile, there is no mention of it there, so perhaps its enough of a 'special case' to have to do it in a non-obvious way. I'll make a Debian bug requesting the manpage be updated to note this.

You'd need the extra quotes if sshfs were using the shell (via system) to call ssh, but this shouldn't be required. It'd be less than ideal if sshfs were using system, but since it's using execvp, it should be fine. If you were using system, the shell would strip the quotes yet again, but you're not, so that shouldn't be an issue. Though, to be honest, I'd suggest using ~/.ssh/config to configure your identity file for special hosts so that you don't need to type it for ssh or for sshfs :) ------------------------------------------------------------------------------ The Go Parallel Website, sponsored by Intel - in partnership with Geeknet, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials, tech docs, whitepapers, evaluation guides, and opinion stories.

If you just add -oIdentityFile="foo bar" then the shell will strip those quote marks. Try something like this: -oIndentityFile='"foo bar"'. The outer single quotes will protect the inner double quotes. Note: exactly the same thing is required if you just start ssh, not sshfs. I think the sshfs behavior of passing arguments verbatim to ssh is fine.

I have a SSH server to access where I use a special private keyfile that is stored in a path with spaces.

This is a temporary solution for a problem I have which will be resolved longer term by ldap and having these centrally managed. The issue is that, on the server, the user has uid 1008 and gid 1003. On the client, that user has uid/gid 1000. I have sshfs v2.4 and have tried using the uidmap/gidmap feature and apparently I'm just not able to figure it out. The local user name and group is simply 'vmail' and I have my uidfile/gid files set thusly: sshfs.uidmap vmail:1008 sshfs.gidmap vmail:1003 Unfortunately the permissions are wrong and I can't even look at the directory when mounted this way: ls: cannot access qmail: Permission denied d????????? ? ? ? ? ? qmail The command I am using is this: sshfs -d -p 22 -o "allow_other,suid,idmap=file,uidfile=sshfs.uidmap,gidfile=sshfs.gidmap" root&lt; at &gt;10.0.1.92://mnt/data/replicated/mail/ qmail Do I have something backwards perhaps? I can't tell what the issue is and would appreciate any pointers. Thanks.

The -u option for sftp-server sets the umask. The files are created with the owner of the sftp-server process. The owner of the sshfs process or the owner of the process doing the create operation are ignored. This is not considered a bug. If you want to create hte files as "cherokee" you should connect to "cherokee&lt; at &gt;server" with sshfs. Or if that's not possible, run the sftp-server with "sudo -u cherokee ..." Note, you don't have to edit the sshd_config on the server, you can also create a script that does this and invoke sshfs with "-osftp_server=path/to/sftp-startup-script" Thanks, Miklos ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
