RoS 3.22 sftp bugs

RouterOS General
1

Hello, MikroTik Team! This message was writted to support by email, but no reply was sent…
I have found some bugs in version 3.22 (and earlier). Yes, in 3.22!

**1.**Let’s look at demo.mt.lv or demo2.mt.lv.
group demo can access via ssh, but not via ftp. ssh means sftp also!
With help of sftp we can remove, modify and change files. But this is unexpected behavior, isn’t it?

**2.**Another one small bug about sftp. Access to router via sftp is not shown in logs.

**3.**It seems to me there is no correct free space limitation on the router:

Uploading .//testspeed.bin to /.//testspeed2.bin
 .//testspeed.bin                                0%    0     0.0KB/s   --:-- ETA
 Couldn't write to remote file "/.//testspeed2.bin": Failure
 .//testspeed.bin                                                                                                            -2147483648% -4629738075075568414

and data still transferring, although:

all your reports were accepted and some already fixed, don’t worry!

I like MikroTik. Thanks! But you could respond by email - i would not worry :wink:

3 business days. we get a lot of email

5

Sympathizing with you. I understand that you are very loaded in connection with the issuance of 3.22.

6

no, not about new versions, we always get a lot of mail.

7

your fixes cause putty sftp executable to fail after “ls” command.
sftp should be functional with read permissions, like ssh if your defined read privileges for group demo.

8

which fixes?

9

I don’t know exactly which.
But your fixes cause sftp not working. I think it should be able to communicate (initialize communication) with RoS via sftp and list directory content according to file and directories permissions. Your fixes disallow this at all. It is not correct way :wink:

10

the fixes will be only included in the next version, so you haven’t seen them. how do you know what these fixes will cause :smiley: ?

OK, i’m waiting for new version =)
