Advanced Monitoring and VPN Troubleshooting commands / hidden commands

For VPN debugging, which enables logging to the KMD log by default without the need to commit:

>request security ike debug-enable local <ip-address> remote <ip-address> level <level>

 and to turn off:

>request security ike debug-disable

Review logs written to /var/log/kmd:

> show log kmd

Checking the debug status:

> show security ike debug-status

For taking a tcpdump of an interface to analyze with Wireshark or similar (Hidden command):

>monitor traffic interface ge-0/0/1.0 write-file test.pcap

 Can be viewed on the SRX also (Hidden command):

>monitor traffic read-file test.pcap

To see default config settings (Hidden command):

# show groups junos-defaults

>show configuration groups junos-defaults

>show configuration groups junos-defaults applications

To see some system limits:

>show log nsd_chk_only

To see currently working Junos applications definitions (Hidden command):

>request pfe execute command “show usp app-def tcp” target fwdd
>request pfe execute command “show usp app-def udp” target fwdd

If you dont have the root login and still you want to capture output on PFE withough going to vty mode. Here is the way:

>request pfe execute target fwdd command “show usp threads”<<<<Just add pfe commands in colun” “.

To make all daemons re-read the configuration. (Hidden command):

# commit full

Another hidden command  useful when troubleshooting is:

> show chassis cluster information ?

Disabling UTM process (Hidden command):

admin@AbedFirewall# set system services utmd
syntax error.

admin@AbedFirewall# set system processes utmd disable

admin@AbedFirewall# show | compare
[edit system]
+ processes {
+ utmd disable;
+ }
admin@AbedFirewall# commit check
configuration check succeeds

ALG Configuration (hidden command):

run show security alg configuration

(sa instead of security-associations) (hidden command):

> show security ike sa
> show security ipsec sa

usefull in HA  (hidden command):

root@SRX# run set chassis cluster control-link-vlan ?
Possible completions:
disable Disable control VLAN tag
enable Enable control VLAN tag
reboot Reboot the system after setting the identifiers

Another good one (hidden command):

admin@AbedFirewall> start shell pfe network fwdd
