This was in the depths of this article here.
Putty – Auto Save Sessions
Problem
Remembering what happened in your last putty session!
Solution
Within Session > Logging > {all session output } insert the following
C:\Users\<user>\Documents\Projects\PUTTY SESSIONS\&H-&Y&M&D&T.log
It will save all session output into the folder specified with the filename of Host-Year-Month-Day-Time.log
Save this in the default profile to enable it for future use.
I am using putty Release 0.67
F5 – TCPDump Basics
Problem
Needing to monitoring the traffic on an F5.
Solution
Running a packet capture over SSH and then grabbing the file using sftp or winscp.
tcpdump -s0 -nni 0.0 host <Client_IP> and port <number> and host <VS_IP> -w /var/tmp/Monitor_Resets.pcap where: -s0 gives the complete packet. -nni disable service port lookups, dns lookups and specifies internal interface
All the rest of the options can be found at F5 here.
Cisco Firepower 6.1.0 Upgrade Fail
Problem
I hit this Firepower bug while upgrading two 5525x firepower modules to 6.1.0. Everything appeared normal until i got to one of the 6.1.0 firepower images.
The error appeared in the sfr console logs as:
Cisco-Firewall# show module sfr log console DB error - will retry: Cannot connect to DB at /usr/local/sf/lib/perl/5.10.1/SF/SFDBI.pm line 588. DB error - will retry: Cannot connect to DB at /usr/local/sf/lib/perl/5.10.1/SF/SFDBI.pm line 588. DB error - will retry: Cannot connect to DB at /usr/local/sf/lib/perl/5.10.1/SF/SFDBI.pm line 588.
Solution
This ties in with following bug at Cisco.com.
Re-imaging SFR module to 6.1 fails on ASA version 9.5(2) : CSCvb53856
An upgrade to the ASA software to 9.6 resolved the issue!
