2021-10-03 Thread Sunhux G
a vendor is setting up on-prem internal servers for us: vendor told us he needs SSL certs for the 5 servers (there's 5 URLs given) not for users to access but for server to server communications Q1: Shall we use self-signed certs in this case & usually for how long these certs should be valid

Also, can we safely say CVE-2019-0217 & CVE-2019-0215 affects "2.4.17 through 2.4.38 with MPM event, worker or prefork" only (just like CVE-2019-0211)? How do I check if we have "MPM event, worker or prefork" in our Apache? On Sat, Apr 6, 2019 at 10:59 PM Sunhux G wr

Are above CVEs affecting Apache httpd (ie web servers) 2.4.x only & other lower versions (eg: our Solaris 10's Apache/2.0.63) are not affected? Can point me to where to get the patches for RHEL7/RHEL6 in Red Hat support portal or anywhere else that's reliable?? Sun

Note that in my current Apache config file, there's a line below which does not mention anything on Diffie-Hellman, so my guess is Apache must have selected /enabled DH by default. How can I explicitly turn it off? SSLCipherSuite HIGH:MEDIUM:!aNULL:+SHA1:+MD5:+HIGH:+MEDIUM I'm thinking of

Yes, there are entries. So I have to get our monitoring team to tune CA to poll every 30 secs for 10 mins to be sure we don't get false alerts? U On Sun, Dec 26, 2010 at 2:40 AM, Joost de Heer jo...@sanguis.xs4all.nlwrote: On 12/25/2010 05:08 PM, sunhux G wrote: Question is how do I
