Tendo problemas ao criar um Proxy SOCKS5. Não pode Tunnel dispositivo

Question

Eu tenho uma máquina de desktop em minha casa que ive se transformou em um servidor SSH Ubuntu (desktop 14 LTS) usando o OPENssh. Eu posso SSH em minha máquina localmente usando autenticação de chave pública (& amp; Putty do meu laptop win8.1) e formar fora da minha LAN sem problemas. Eu estou tentando criar um túnel SSH (porta dinâmica para frente) para o meu PC em casa, mas continuo recebendo erros ao tentar se conectar. Tenho acompanhado este artigo: link e eu consultei muitos outros.

Após minha conexão SSH ao meu PC doméstico autenticar, estou chamando o comando

ssh -D 1080 dell

* dell é o nome do meu windows 8.1 laptop im usando com putty para se conectar ao meu servidor SSH

Se eu estiver na minha LAN, recebo um erro após o tempo limite da conexão, que é lido

ssh: connect to host dell port 22: Connection timed out

Por isso, nos meus testes, tentei ligar-me fora da minha rede doméstica e recebi um erro semelhante

ssh: connect to host dell port 22: No rout to host

Eu também tentei

ssh -D 1080 [email protected]

Isso me dará um erro de autenticação. Se eu disser "sim" para se conectar, recebo uma "Permissão negada (publickey)". erro

Neste ponto eu não tenho certeza se a minha sintaxe está correta no meu comando ssh -D ou se o meu problema está em outro lugar. Eu verifiquei novamente o meu arquivo sshd_config bem e eu tenho o meu arquivo de configuração configurado com AllowTcpForwarding yes & amp; X11forwarding sim

Qualquer ajuda para diagnosticar este problema é muito apreciada!

EDIT: Consegui fazer com que minha conexão funcionasse usando ssh -D 1080 [email protected] depois que eu configurei o Putty corretamente. Eu estava usando o Pageant para fazer login inicialmente e desde que eu não especificou para putty onde minha chave pública foi a autenticação para o encaminhamento dinâmico de porta estava falhando.

No entanto, ainda sou incapaz de fazer uma conexão em túnel. Eu continuo recebendo o erro: tunnel device open failed. Could not request tunnel forwarding. continuo procurando pelo meu ssh_config & amp; sshd_config arquivos e não consigo encontrar nenhum problema ...
