Model: j6350 JUNOS Software Release [10.4R4.5] Following is the current configuration that we have for ssh:-
set system login user xxx authentication ssh-rsa "ssh-rsa AAAAB" set system services ssh set security ssh-known-hosts host 10.x.x.x rsa-key set security ssh-known-hosts host 10.x.x.x rsa-key set firewall family inet filter Access term AllowSSH from port ssh set firewall family inet filter Access term DenySSH from port ssh Following firewall filter is in place:- set interfaces ge-0/0/1 unit 0 family inet filter input Access set firewall family inet filter Access term AllowSSH from address X.X.X.X/16 set firewall family inet filter Access term AllowSSH from address X.X.X.X/16 set firewall family inet filter Access term AllowSSH from address X.X.X.X/16 set firewall family inet filter Access term AllowSSH from address X.X.X.X/16 set firewall family inet filter Access term AllowSSH from protocol tcp set firewall family inet filter Access term AllowSSH from port ssh set firewall family inet filter Access term AllowSSH then accept set firewall family inet filter Access term DenySSH from protocol tcp set firewall family inet filter Access term DenySSH from port ssh set firewall family inet filter Access term DenySSH then reject set firewall family inet filter Access term default-term then accept I am now going to add loopback address as well:- set interfaces lo0 unit 0 family inet filter input Access Important thing is that all these alerst started when we applied the filter, may be something wrong with the ocnfiguration that we have applied.
