Estou tentando colocar alguns softwares de blog em um servidor remoto organizacional. Eu tentei configurar uma chave SSH, mas estava tendo problemas e decidi que colocar o blog em funcionamento era mais importante do que lidar com o problema da chave SSH, então eu ssh-keygen -R remoteserver.com .
Agora posso fazer login com sucesso com ssh -v [email protected] e a senha correta. Uma vez logado, posso me mover e ler qualquer arquivo e diretório que eu possa ler.
Mas quando tento editar um arquivo -rw-r--r-- existente com o VIM, ele aparece como somente leitura, se eu tentar editar as permissões, recebo chmod: file.ext: Operation not permitted e, se eu tentar, scp , um novo arquivo de Na minha máquina local, sou solicitada a senha do usuário remoto e, em seguida, obtenho scp: /home/path/to/file.ext: Permission denied .
Como não tive nenhum desses problemas antes de tentar configurar a chave ssh, suspeito que essas anomalias sejam um efeito colateral disso, mas não sei como solucionar isso. Então, o que um servidor newb tolo, como eu, precisa fazer para recuperar o recurso de edição como um usuário remoto?
Adendo 1:
Meus userids são diferentes entre minha máquina local e o servidor remoto.
- Para ssh, eu
ssh -v [email protected] .
- se eu
whoami obtiver remoteuser
- Para scp eu
scp file.ext [email protected]:/path/to/file.ext do diretório local com file.ext enquanto logado como o usuário local.
- se eu
whoami obtiver localuser
O ls -l para dois arquivos diferentes que eu tentei scp:
-rw-r--r--@ 1 localuser localgroup 20 Feb 11 21:03 phpinfo.php
-rw-r--r-- 1 root localgroup 4 Feb 11 22:32 test.txt
O ls -l do arquivo que eu tentei para o VIM:
-rw-r--r-- 1 remoteuser remotegroup 76 Jul 27 2009 info.txt
Adendo 2:
No passado, eu configurei ssh-keys para repositórios git. Eu não quero destruí-los completamente, então, em uma tentativa de seguir linha de pensamento de um cervo eu renomeado meu ~/.ssh/ para ~/.ssh-bak/ , depois testei os diferentes tipos de acesso. A versão abreviada dos comandos e resultados do terminal está abaixo; Eu acho que tudo está funcionando até a 8ª linha do final.
ssh -v
