resolve iOS Information.app failure to hook up with SMB server? (as much as iOS 18)

With a view to repair each points optimally, you will want (admin) entry to your SMB server configuration; though a workaround exists for Difficulty 2 in the event you do not.

Difficulty 1

Though information.app seems to carry out most of its site visitors over the SMB3 protocol, some preliminary connection exercise solely seems to work if the server accepts SMB2 requests. This requires adjusting the server’s configuration (see under).

Difficulty 2

Answer 1: delete previous/clashing “server” connection

Deleting a connection to a earlier server that gives a share with the identical title (information.app -> important menu (…) -> hook up with server -> (i) -> Take away) solves the problem.

This can be a workaround in case you do not have entry to the server config though you will solely be capable of entry one of many “clashing” servers/shares at a time, which may very well be irritating.

Answer 2: guarantee distinctive SMB share title throughout servers

A greater workaround is to make sure that the title of the SMB share is exclusive throughout the connections saved/remembered in your information.app. In my case, the usual configuration of my servers was to name them smth like smbshare; making an attempt to entry multiple server with the identical share title, causes the problem, which appears like a bug in information.app IMHO (the share names ought to be certified by the server title).

Difficulty 3

This seems to be brought on by the iOS shopper utilizing new Samba performance? After a bitof analysis, I stumbled upon this text, which particularly recommends some configuration to make Samba work higher with Apple units; one in all which aptly implies enabling the fruit extension, which fastened the “read-only” difficulty for me:

[global]
...
vfs objects = fruit streams_xattr

regulate a SMB server’s config to resolve each points

The under process and instance are based mostly on Ubuntu however they need to work equally on different *NIX/*BSD derivatives (and NAS) that use Samba because the SMB server software program, albeit presumably with totally different paths/filenames and so forth:

1. Logon to your SMB server and run sudo -i to entry root privileges.
2. Edit /and so forth/samba/smb.conf
3. For difficulty 1, you will need to guarantee server min protocol (sometimes discovered within the [global] part) is ready to SMB2.
4. For difficulty 2, find the title of the share (positioned between brackets; in my instance [smbshare]) and alter it to smth distinctive. For instance, by together with the host title, which could be stubbed as %h in the event you wish to maintain your config information standardized.
5. systemctl restart smbd

A pattern smb.conf that works for the iOS information.app

Here is an instance smb.conf that works nicely with iOS information.app and strives to be moderately safe (SMB is a well-known assault vector!). Suggestions – notably if it improves safety – is welcome.

[global]
        server string = %h
        server function = standalone server
        interfaces = lo eth0
        bind interfaces solely = sure
        disable netbios = sure
        smb ports = 445
        log file = /var/log/samba/smb.log
#        log degree = 3
        max log measurement = 1000
        map to visitor = dangerous person
        smb encrypt = required
        server min protocol = SMB2
        shopper min protocol = SMB3
        vfs objects = fruit streams_xattr

[%h]
        legitimate customers = MY_SMB_USER
        path = /house/MY_SMB_USER/SHARE
        accessible = sure
        browseable = sure
        learn solely = no
        power create mode = 0660
        power listing mode = 2770

• [%h] makes use of the server title because the share title, which solves difficulty 2 single-handedly. It simply must be smth distinctive to workaround file.app’s slightly surprising bug.
• log degree = 3 (or above) is helpful to extend verbosity of logs to troubleshoot points.
• You will want to regulate interfaces = and MY_SMB_USER to fit your circumstances (ip hyperlink present is your buddy to find your interfaces’ names). interfaces restrictions could be neglected however that is undoubtedly not beneficial on a machine immediately going through the Web.

Be aware on server OS

Though the examples above check with an Ubuntu SMB server, the identical difficulty(s) seem to exist with Home windows servers (so the bugs look like within the iOS information.app), as evidenced by the Apple boards query linked within the query.
