Re: [Burp-users] rebuilt Windows laptop, problem initializing certificates

[Bo G. <bo...@bo...>]

Doing some additional digging, I see this in syslog:

May 25 11:27:04 blort burp[53722]: Client MrsWeasley wants a certificate 
signed
May 25 11:27:04 blort burp[53722]: Received: /etc/burp/CA/MrsWeasley.csr
May 25 11:27:04 blort burp[53722]: Signing certificate signing request 
from MrsWeasley
May 25 11:27:04 blort burp[53722]: Running '/usr/sbin/burp_ca --name 
MrsWeasley --ca burpCA --sign --batch --dir /etc/burp/CA --config 
/etc/burp/CA.cnf'
May 25 11:27:05 blort burp[53722]: /usr/sbin/burp_ca returned: 1
May 25 11:27:05 blort burp[53722]: Error running /usr/sbin/burp_ca
May 25 11:27:05 blort burp[53722]: Error signing client certificate 
request for MrsWeasley
May 25 11:27:05 blort burp[53722]: exit child
May 25 11:27:05 blort burp[1267]: pipe from child 6: end of data
May 25 11:27:05 blort burp[1267]: pipe from child 6: disconnected fd 6

It would appear that burp_ca is failing for some reason.
