I am using CentOS 7 server. Yesterday's night, I lean using SSH and SFTP. Everything is ok. I connect to SFTP via File Zilla on macOS 10.14.3



SFTP:



sftp://103.48.194.xxx
user: root
password: ****
port: 22


But today, I cannot use also SSH and SFTP. With SSH by macOS Terminal, I see I enter correct password, but cannot finish success



The result of ssh -v root@103.48.194.xxx is

    Looks like root's login shell is failing (/bin/bash: No such file or directory)

    @Kusalananda That isn't going to work. The SSH server uses the account's shell to launch any command requested by the client. If the shell isn't working, then launching commands won't work.

  • @Kenster Ah, that may well be true. I don't tend to delete shell binaries that are in use so I haven't run into this...

I can still access server (root account) by web console.



I need to connect to SSH, SFTP from macOS.






centos ssh sftp

I am using CentOS 7 server. Yesterday's night, I lean using SSH and SFTP. Everything is ok. I connect to SFTP via File Zilla on macOS 10.14.3



SFTP:



sftp://103.48.194.xxx
user: root
password: ****
port: 22


But today, I cannot use also SSH and SFTP. With SSH by macOS Terminal, I see I enter correct password, but cannot finish success



The result of ssh -v root@103.48.194.xxx is

    @Kusalananda That isn't going to work. The SSH server uses the account's shell to launch any command requested by the client. If the shell isn't working, then launching commands won't work.

Clash Royale CLAN TAG #URR8PPP 1 How can I extract a single band from multi-band raster in QGIS? I have an remote sensed image which has 6 bands (including NDVI band), I want to display each band separately, but have no idea how to do. I have seen some questions similar here but none worked for me.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
