OpenSSL creates CA serial file

Saturday, April 12th, 2008

Sguil Logo I have encountered error below when I followed the Sguil OPENSSL.README to generate a certificate with a local CA for my Sguil 0.7.0 installation on FreeBSD 7.0 Release.

[[email protected]]# openssl x509 -req -in sguild.req -CA CA.pem -CAkey privkey.pem -CAserial file.sr1 -out sguild.pem
Signature ok
Getting CA Private Key
Enter pass phrase for privkey.pem:
file.sr1: No such file or directory
82464:error:02001002:system library:fopen:No such file or directory:/usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/bio/bss_file.c:352:fopen('file.sr1','r')
82464:error:20074002:BIO routines:FILE_CTRL:system lib:/usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/bio/bss_file.c:354:

OpenSSL Logo From the error message, it is obvious that I did not have the file.sr1 there. Since this was the first time I used the CA to sign the certificate, I would need to create serial key containing serial key. So I run -CAcreateserial as below:

[[email protected]]# openssl x509 -req -in sguild.req -CA CA.pem -CAkey privkey.pem -CAcreateserial -out sguild.pem

This created a new file ( containing a serial number. The next time I have to use the -CAserial option when I create new certificate, and specify the path to this file name. The serial number will be incremented each time a new certificate is created.

Sguil 0.70 and Wireshark 1.0.0 Released

Monday, March 31st, 2008

Sguil LogoIt seems a bit late to announce both releases. After a long development process and beta testing, Sguil 0.7.0 has finally been released. It does not take long for modsec2sguil to work with the latest release as well. I have not upgraded my Sguil installation to 0.70 yet, but it won’t take a long time for me to do that because I plan to upgrade the hard disk as well, so every thing will be fresh installation, including the OS - FreeBSD 7.0.

Wireshark LogoIn my opinion, every network analysts should get familiar with these 2 tools, especially Wireshark. In this new version, Wireshark team has fixed few security vulnerabilities, and there is an experimental package for Mac OSX Intel as well.

Other than these releases, I have done a small upgrade from FreeBSD 6.2R to FreeBSD 6.3R recently, which I refer to here. This is only applicable if you are running GENERIC FreeBSD kernel.
