I have Cywgin running on a windows VM and I'm having problems keeping a stable SSHD service running.
The issue is that file permissions on the /etc/ssh_host_ecdsa_key, /$home/.ssh etc directories are being randomly reset so SSH connections are refused because I am using strict mode. When I stop the SSHD service, reset all the file and folder permissions to 700, restart SSHD, SSH connections work fine until they apparently randomly stop and sure enough all the relevant sshd directory and file permissions are reset.
Has anyone encountered this problem before and know a possible solution?
In case somebody is researching a similar issue, the problem was due to instability on the VMs C drive after hibernating, logging off etc.
The solution was instead of installing Cywgin directly on the VM, install Cywgin a separate networked drive mounted on the VM. Works perfectly and no more instability issues.

I'm trying to connect to an Azure file share from my Mac running High Sierra 10.13.6 using the following command:
mount_smbfs -d 0777 -f 0777 //dolphins:PASSWORDHERE#dolphins.file.core.windows.net/models /Users/b3020111/Azure
However I keep getting the error:
mount_smbfs: server connection failed: No route to host
I have turned off packet signing in /etc/nsmb.conf:
[default]
signing_required=no
After looking around the web I seem to be at a loss as to where to go, any help is appreciated.
I got it working with azure provided connection example.
mount_smbfs -d 777 -f 777 //user:key#storageurl/folder ~/mountfolder
Folder in file share needed after url and mountfolder must exist.
But the main reason for "No route to host" was because the access key had forward slash in it! I did a rebuild of key1 until I got a key without forward slash.
BUT! Be aware, rebuilding key will kill all mounts and connections to that storageaccount.
Came across this issue myself today. Do double check that your ISP does not block SMB port 445. In my case, AT&T does actually block this port. I found this in their guide http://about.att.com/sites/broadband/network
The solution for me was to connect with a VPN which I'm already hosting on Azure. Additionally as others have mentioned in this thread, escape any / with %2f. Also, add the share name in the connection URL. For example, if your share name is my-data then the connection URL should contain xxx.file.core.windows.net/my-data.
This is omitted for some reason in the Azure docs/UI and was required for successful connection on OSX.
It was the "/" after all. I had to regenerate the key over ten times till I get a key that doesn't have the "/" character and then it worked fine through the terminal.
It should work using the following syntax:
mount_smbfs //<storage-account-name>#<storage-account-name>.file.core.windows.net/<share-name> <desired-mount-point>
Without adding the permissions.
Via Finder:
Source can be found here
"mount(2) system call failed no route to host "
while mounting azure file share on linux vm we can have this error.
In my case One package was missing which is - cifs-utils
So, I have used below command
"sudo yum install cifs-utils -y" to resolv the issue.
Important to allow port 445 (TCP) to smb communication. If you don't access it, your firewall block it! Please enable it and try it again.
I ran into this same problem, and while I was never able to get it working through the terminal I did manage to get it resolved in finder.
Essentially the same instructions as #Adam Smith-MSFT, however one key difference.
I created a directory via Azure's web interface, and after that I was able to connect by adding /<directory-name> to the connection string. Without a directory this would not work at all.
Setup:
Virtual Machine: VMware Fusion with CentOS 7.4.1708 with NFS Server config:
"/dev/ServerPath" 10.20.0.104(rw,fsid=0,sync,crossmnt,no_subtree_check,all_squash,anonuid=1111,anongid=1111)
Local Latest OSX:
Mount:
sudo mount -t nfs -o resvport,rw 10.20.0.136:/dev/LocalPath /Users/USERNAME/dev/ServerPath
Everything is working great except at opening the Project (Directory) in PhpStorm, each ~500ms it (re)indexes and a loading bar shows this operation (Updating Indices). Except of danger of epileptic seizure I am afraid about the HDD writing operations on SSD and therefore I wanted the ask the Community if such Issue can be fixed and how? The Synchronisation Setting was disabled. Maybe has this something with the way the NFS is exported/mounted?
PhpStorm mentions:
"External file changes sync may be slow: Project files cannot be watched (are they under network mount?)"
Any Tips are appreciated, thank you in advance!
As far I could tell, the problem is not with the NFS Mount or the Infrastructural issue but how PhpStorm renew it's Indexes. One quick but short living fix is to invalidate the Indices and Cache by going to:
File > Invalidate Caches / Restart
After that, there is no more quick indexing of Directories and till some unknown change, the Filesystem is handled properly by PhpStorm.
Problem
I was working with bento/centos7.2 box. I did a vagrant up and while it was booting up, I noticed the box has an update and I instinctively cancelled the operation (which I suggest not to do, ever!). So I went ahead and did vagrant destroy, rm -rf .vagrantjust to be sure (Again, I suggest not to do, ever!). I removed my box by vagrant box remove bento/centos7.2 and did vagrant up and ended up with this:
Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
Environment
Ubuntu 16.04
Vagrant 1.81
Centos 7.2 Box
Things I tried
Following are the threads I have tried:
vagrant + virtualbox Timed out while waiting for the machine to boot
Timed out while waiting for the machine to boot when vagrant up
Vagrant "Timed out while waiting for the machine to boot."
When I enabled the GUI, I realized the box is booting up properly; it's just stuck at login screen(bug in box with ssh?). Screenshot:
Any help is much appreciated.
There are multiple possibilities that cause this issue:
Try running:
vagrant reload
This re-installs the guest-additions on the box.
Try opening Virtualbox (GUI interface) and the open the virtualbox (console). The box might for example be
i) waiting for fsck (filesystem check) if it was shutdown uncleanly
ii) login to the box over Virtualbox GUI by using the default username/password (typically vagrant/vagrant) and figure out is the ssh server running on the box or not.
Run
vagrant ssh-config
and see to what port and by which ssh key it is trying to use. Use them manually e.g.:
ssh -i <identity_key_location> vagrant#localhost -p 2222
So, I tried to set up a public SMB share with Samba on CentOS 7. Now, I have it set up, and I have a headache. But, sweet victory. I'm posting this here for all y'all so that you don't need to waste your time. It's actually easy, you just need to know the hoops you need to jump through. I'll also edit the Samba wiki.
The first problem was that it wouldn't connect at all, except locally:
Remote Connection (my Linux desktop):
-------
[root#my-desktop ~]# smbclient //sambaserver/PublicDocs -N
Error connecting to 192.168.100.97 (No route to host)
Connection to cgybkp01 failed (Error NT_STATUS_HOST_UNREACHABLE)
On Windows 8, using Windows Explorer, after typing "\\sambaserver" into the address bar, the progress bar would wait, wait, wait, then time out. The error message was:
Remote Connection (my Windows 8 desktop):
Windows cannot access \\sambaserver
Check the spelling of the name. Otherwise, there might be a problem with your network. To
try to identify and resolve network problems, click Diagnose.
This ended up being a problem with firewalld. To unblock Samba, I needed to add this line to /etc/firewalld/zones/public.xml :
<service name="samba"/>
Perfect, now I can connect!
But, I was actually mounting an NFS share, so I had one more issue, with SELinux. Now, when I attempt to connect with smbclient...
smbclient //sambaserver/PublicDocs -N
I can connect, but when I try to ls, I get the error: "NT_STATUS_ACCESS_DENIED" in CentOS 7. So, how do I connect?
The first thing everyone recommended that I try was file permissions. If you're not familiar with file permissions in Linux, I'd recommend trying those first. But for me, that didn't work, because SELinux was blocking me.
To see all of the SELinux options for Samba, type:
getsebool -a | grep samba
getsebool -a | grep smb
The one I needed to change was samba_share_nfs, because I was sharing an NFS mounted directory:
setsebool -P samba_share_nfs on
CentOS maintains a list of these booleans here.
Agenda: To have an common Project Folder between Linux and Windows
I have changed my document root from : /var/www/html to /media/mithun/Projects/test in my ubuntu machine 14.04
I get error as :
Forbidden
You don't have permission to access / on this server.
Apache/2.4.7 (Ubuntu) Server at localhost Port 80
So i added some scripts to : sudo gedit /etc/apache2/sites-available/000-default.conf
# DocumentRoot /var/www/html
DocumentRoot /media/mithun/Projects/test
But Document Root /var/www/test works but not with Windows NTFS Partition Drive.
Even after referring to :
Error message "Forbidden You don't have permission to access / on this server"
Issue with my Ubuntu Apache Conf file. (Forbidden You don't have permission to access / on this server.)
No success :( So kindly assist me with it...
Note: Projects is an New Volume (Internal Drive: In Windows its E:/ Drive)
#Lmwangi - Please check my updates for your reference below:
Output of : ls /etc/apparmor.d/

I tried killing apparmor:
sudo /etc/init.d/apparmor kill
I receive output as : Usage: /etc/init.d/apparmor

After this, i was also able to restart apache successfully
maybe the problem is simple : is your new root directory accessible to the www-data user ?
Try :
$ chown -R www-data:www-data /media/mithun/Projects
As you have you have discovered by now, you cannot just manipulate permissions on an NTFS partition (using tools like chmod)
However, you can try forcing a given owner/permissions for the entire partition when you mount it.
Now the wayto do this, depends on the NTFS-utilities you are actually using (and which i don't know, so I'm assuming you are using ntfs-3g)
E.g. mount the partition with the following parameters (replace dev/sdX with your actual partition, and /path/to/wheredrive/is/mounted` with your target path):
mount -o gid=www-data /dev/sdX /path/where/the/drive/is/mounted
should make all the files on the partition belong to the www-data group.
If the filesystem sets the group ownership explicitely, this still might not work.
In this case, you might need to setup a usermap, that maps your windows users/groups (as found on the partition) to your linux users/groups.
The ntfs-3g.usermap utility will help you generate an initial usermap file, which you can then edit to your needs:
ntfs-3g.usermap /dev/sdX
Then pass the usermap to the mount options:
mount -o usermapping=/path/to/usermap.file /dev/sdX /path/where/the/drive/is/mounted
I suspect that you have apparmor enforcing rules that prevent Apache from reading non-whitelisted directory paths. I suggest that you
Edit the apparmor config for Apache to access your custom path. You'll need to hunt around /etc/apparmor.d/ . You may also find that using apparmor in non-enforcing mode helpful.
$ sudo aa-complain /etc/apparmor.d/*
Use mod_apparmor? See this
Or disable apparmor completely. See this
My order of preference would be 1,3,2. That should fix this for you :)
While using ubuntu with windows I faced same issue and it is resolved by remounting drive with read and write access. Below command will help you to do that:
sudo mount -o remount,rw /disk/location /disk/new_location
If it is still not working then in windows os, go to the power options and disable fast startup.
When you shut down a computer with Fast Startup enabled, Windows locks down the Windows hard disk. You won’t be able to access it from other operating systems if you have your computer configured to dual-boot. Even worse, if you boot into another OS and then access or change anything on the hard disk (or partition) that the hibernating Windows installation uses, it can cause corruption. If you’re dual booting, it’s best not to use Fast Startup or Hibernation at all.
