Append a string to a router's flash file

[Florin Barhala]

Hi guys,

Just setup a small but useful Remote Access VPN accounting script:

event manager applet VPN_Accounting_UP 
 event syslog pattern "%CRYPTO-5-SESSION_STATUS: Crypto tunnel is UP"
 action 1.0 cli command "enable"
 action 1.2 cli command "show clock | append flash:/VPN_Accounting"
 action 2.0 cli command "show crypto session brief | append flash:/VPN_Accounting"
 action 3.0 append flash:/VPN_Accounting "=================================================="

And here's the output as I just almost need it:

Cisco-Tests#more flash:/VPN_Accounting

14:28:50.680 EEST Mon Aug 4 2014

Status: A- Active, U - Up, D - Down, I - Idle, S - Standby, N - Negotiating 
        K - No IKE
ivrf = (none)
           Peer     I/F        Username          Group/Phase1_id   Uptime Status
  85.24.27.62    Vl11         ra-user                  VPNRA 00:02:34    UA

15:10:33.492 EEST Mon Aug 4 2014

Status: A- Active, U - Up, D - Down, I - Idle, S - Standby, N - Negotiating 
        K - No IKE
ivrf = (none)
           Peer     I/F        Username          Group/Phase1_id   Uptime Status
  85.24.27.62    Vl11         ra-user                  VPNRA  00:00:00    UA

My only question is how can I add after the last output append some string like: "==================================".

Mainly just action 3.0 is not working...

Thanks!

Do not know any easy way to do that, but you could create a tcl script that just "puts" its argument and then do "tclsh puts.tcl ========================= | append flash:/VPN_Accounting"

Kind of an "echo" command :)

The append action is for appending a string to another string.  If you have EEM 4.0, you can use the file open and file write actions, but it's not clear what version of IOS you have.  As a general workaround, you can try what cgm suggests, or convert this applet to Tcl at http://www.marcuscom.com/convert_applet/ then add:

set fd [open "flash:/VPN_Accounting" a]

puts $fd "========================================"

close $fd

As Joseph said, the file operation are available from 15.2(2)T. Reference here

If you are able to use the file actions, you could do it as in the example below:

event manager applet VPN_Accounting_UP
 event syslog pattern "%CRYPTO-5-SESSION_STATUS: Crypto tunnel is UP"
 action 1 file open LOGFILE flash:VPN_Accounting.txt a+
 action 2 cli command "enable"
 action 3 cli command "show clock"
 action 4 file puts LOGFILE "$_cli_result"
 action 5 cli command "show crypto session brief"
 action 6 file puts LOGFILE "$_cli_result"
 action 7 set filebuffer "=================================================="
 action 8 file puts LOGFILE "$filebuffer"
 action 9 file close LOGFILE
