Failed to mount (inactive): mount error(13) when mounting CIFS from Synology

[3246]

@nebulon found it!

It doesn't like my super strong password, which contains special characters

When I wrap the password in "..." it accepts it!

[nebulon]

@3246 ah so you wrapped it in quotes in the .mount file for systemd? If this is the case, I guess we should always add quotes when generating this file.

[girish]

@3246 Can you tell us what special characters it has? Does it have a comma or double/single quote ? From what I read from the man pages:

https://manpages.debian.org/testing/systemd/systemd.mount.5.en.html says Mount options to use when mounting. This takes a comma-separated list of options. This setting is optional. Note that the usual specifier expansion is applied to this setting, literal percent characters should hence be written as "%%". . https://www.man7.org/linux/man-pages/man5/systemd-system.conf.5.html has the specifier table. It has no special meaning for double quotes AFAICT.

https://linux.die.net/man/8/mount.cifs says Note that a password which contains the delimiter character (i.e. a comma ',') will fail to be parsed correctly on the command line. However, the same password defined in the PASSWD environment variable or via a credentials file (see below) or entered at the password prompt will be read correctly. . So, maybe we have to create a credentials file for this to be reliable.

@3246 ok, https://www.freedesktop.org/software/systemd/man/systemd.syntax.html has some more.

Can you please try systemd-escape <your-password> and use that instead of quoting in the mount file? If that works, I can fix up our code accordingly.

[3246]

@girish @nebulon thanks both. The previous password contained: @ & ^

It works OK on the command line, where I can escape it using double quotes or just pasting it in the prompt when running interactively.

I will have a go with a test user and suitably complex password and report back, after trying the 'system-escape' option.

Sadly, this did not work. I also tried MD5 hashing but the only reliable way is to use a password without special characters so far

@3246 thanks for trying! If you don't mind trying one more approach:

• Create a credentials file like:

username=username
password=password

• Then in the systemd mount file, do Options=credentials=/path/to/credentialsfile,..other options...

See articles like https://askubuntu.com/questions/1119819/how-do-i-use-a-credential-file-for-cifs-in-etc-fstab

I think we should do one of these:

• When complex passwords are entered in UI, we can inform the user about this limitation, so they don't end up with your situation.

• If credential file works, we will fix the code to use that approach.

[3246]

@girish OK, slowly for those of us who don't read too well ;D

Do you mean /etc/fstab or some other way to put the options line in? I am familiar with the former but even after DuckDuckGoing for 2min not that much more clued in about the latter.

What do I do in the GUI?

[girish]

@3246 ha ha, sorry about that. Let me see if I can make a patch instead and test locally with special characters, might be easier.

[3246]

@girish thank you

I have tried to fix this with https://git.cloudron.io/cloudron/box/-/commit/dbb803ff5e3e837a7c8f49c4890bccc5329946d5 . Let's see if the situation is better in the next release.

I have a similar issue when connecting to a Hetzner StorageBox system:

Failed to mount (inactive): mount error(128): Key has been revoked Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

My settings are the following:

Any tips on how to get this fixed? The git commit is some months old so I thought this might be already included in the latest Cloudron release?

Key has been revoked

I think the error is coming from Hetzner . Did you possible revoke your existing key? Maybe you can generate new keys and try?

[jayonrails]

@girish does key mean the password I received for the login? Or does it mean the authentication with an SSH Private / public key pair?

This would also be possible on Hetzner Storage Box, but is not what I have configured. I am curious because in my understanding a password cannot be revoked, while a private key could be revoked, but is nothing I am using right now.

I will check the credentials again and will let you know the results.

@jayonrails SSH and SAMBA access haven’t been enabled yet, therefore it didn’t worked. After enabling it, everything works perfectly.
