How can I open telnet / ssh to this router?

  • Is 192.168.1.1 actually the D-Link? – Havegooda Sep 12 at 17:44
  • @Havegooda yes sure , When I enter to this ip I get the router web – dlink Sep 12 at 17:49
  • Is this a wireless router? How are you connecting, hardwire or through wireless? It's possible that the router is refusing SSH/22 connections if it's not through ethernet due to a security policy, perhaps? Can you paste the verbose output? (-v flag) – Havegooda Sep 12 at 17:51
  • @Havegooda I attached ssh verbose , I connecting wireless to the router – dlink Sep 12 at 17:59
  • It appears your config is only set to use a PKI cert to connect? I'd take a look at that and see if there's a way to enable user/pass authentication. That router is relatively old, so I doubt it supports PKI in the first place. – Havegooda Sep 12 at 18:02
