We have a client reporting a problem connection to one of our endpoints after they upgraded their appliance that uses SSL 3.0.7. I've read around a little and I believe this is in relation to the recent security issue announced by OpenSSL. Their device I believe uses an IBM APIConnect Gateway. The error they are getting with the connection since the upgrade happened is the following (IP and gtid obfuscated for security): May3014:08:08npe-dp-sac-node1[APIConnect_Gateway][0x8120002f][ssl][error]ssl-client(bsc_dev2_tlsp-tls-client-profile-defaultV1.0.0):trans(4705632)[10.10.10.10]gtid(#################):TLSlibraryerror:error:141E3152:SSLroutines:final_renegotiate:unsafelegacyrenegotiationdisabled I'm concerned after digging around, that our F5 might not be ready or setup to accept traffic from devices that have been updated with this new version of SSL 3.0.7. I am the SME for the F5 support at our company and I don't have a lot of experience on this end of the configuration. Is there something we need to do on the F5 to safely allow this traffic?Solved3.5KViews0likes3CommentsMachine Cert Auth Error - unable to get local issuer certificate
Hi, I've read through quite a few forum post related to this error but couldn't find anything specific to my issue. I have several machines I have been testing my APM policy with however, one is now failing. We use machine certs via our internal PKI. I've tried deleting it's machine cert and enrolling it again. I've tried deleting it's root/stub and installing them again. The certificate store matches my other working hosts. I've tried rebooting the machine and even the F5. Lastly, I've exported the failing machine root and sub and created it's own SSL profile to compare against on the F5 with no luck. It wasn't initially failing and I have not made any changes to the machine. The error I receive for session data is below: 06507f43.session.check_machinecert.auth_ag.nonce 28 ZDJQVjBiV3BqY05oWVhqTTdIdU4= 06507f43.session.check_machinecert.auth_ag.result 1 0 06507f43.session.check_machinecert.auth_ag.signature_verified 1 1 06507f43.session.check_machinecert.last.certificate_revoked 1 0 06507f43.session.check_machinecert.last.certificate_verified 1 0 06507f43.session.check_machinecert.last.error_message 103 X509_verify_cert failed: error : 20 at depth 0, error message:unable to get local issuer certificate 06507f43.session.check_machinecert.last.result 1 0 06507f43.session.check_machinecert.last.signature_verified 1 12.2KViews0likes5CommentsEdit SSL Profile fails with "apiError":26214401
I am trying to edit a server-ssl profile via REST API to add options. The request fails with HTTP 400 :: {"code":400,"message":"\"{ dont-insert-empty-fragments no-tlsv1.3 }\" unexpected argument","errorStack":[],"apiError":26214401} The same operation works well with TMOS shell.

Hi Folks, I want to think this is possible. I am trying to based on the HTTP_REQUEST and host header, select the serverside connections SSL profile. For example, If host header is abc.example.com I want the serverside SSL profile to be the default serverssl. But if the host header is xyz.example.com then I want the serverside SSL profile to be serverssl-insecure-compatible. Teh client side connection works fine, and I am also using a wildcard cert for example.com I've seen a lot of posts on enabling or disabling ssl serverprofiles, but not about selecting which profile to use. here is my code thus far. when HTTP_REQUEST { HTTP::header remove "Accept-Encoding" switch [string tolower [HTTP::host]] { "abc.example.com" { Server ssl profile select goes here pool abc_pool_https } "xyz.example.com" { Server ssl profile select goes here pool xyz_pool } }1KViews0likes6CommentsServer-side SSL Failing
Hello everyone We have a project where we need to provide TLS offload (client-side) and server-side encryption to the back-end web servers. I thought I'd test this out in my lab but seem to be struggling. I have an Apache2 web server configured to serve HTTPS web pages. The certificate presented by the web server is from my lab PKI. Browsing to the server directly from my PC, bypassing the LTM appears all good. The handshake is successfull. Things appear to work. When I introduce the LTM things fail. So far I have created a client-side cert and attached this to a client SSL profile then virtual server. I know this works because if I change the backend web server to a plain HTTP, the offload works just fine. I have imported my two PKI certificates (root/sub) and concatinated them as per sol13302, then installed them. I then attach this chain certificate to the server SSL profile under Configuration > Chain. Then attach the SSL profile to the VS. Even after all this, I get the following error: 'Secure Connection Failed'. If I use OpenSSL to test I get the following: [root@:Active:Standalone] tmp openssl s_client -connect red-https-server.lab.com:443 CONNECTED(00000003) depth=0 C = UK, ST = London, L = London, O = Lab Inc., OU = IT Dept., CN = blue-https-server.lab.com verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 C = UK, ST = London, L = London, O = Lab Inc., OU = IT Dept., CN = blue-https-server.lab.com verify error:num=27:certificate not trusted verify return:1 depth=0 C = UK, ST = London, L = London, O = Lab Inc., OU = IT Dept., CN = blue-https-server.lab.com verify error:num=21:unable to verify the first certificate verify return:1 I understand the error messages, the LTM clearly cannot verify the identity certificate the web server is presenting. If I change the OpenSSL command to use the chain cert, it works: [root@:Active:Standalone] tmp openssl s_client -connect red-https-server.lab.com:443 -CAfile /config/filestore/files_d/Common_d/certificate_d/:Common:LAB-CHAIN-CERT.crt_71998_1 CONNECTED(00000003) depth=2 CN = LAB-ROOT-CA verify return:1 depth=1 DC = com, DC = lab, CN = LAB-SUB-CA verify return:1 depth=0 C = UK, ST = London, L = London, O = Lab Inc., OU = IT Dept., CN = blue-https-server.lab.com verify return:1 Verify return code: 0 (ok) This is really frustrating me as it seems as if regardless of how I configure the SSL profile the handshake keeps failing. Anyone have an idea on where I am going wrong? Thank you633Views0likes3CommentsSSL Cipher error in ltm logfile "Cipher XX:Y negotiated is not configured in profile <sslprofilename>"
I recently moved an HTTPS Virtual Server from an old LTM (running 9.3.1) to a new pair of load balancers running 11.4.1. This particular Virtual Server is using both a client SSL profile and a server SSL profile, pointing at a pool with a single node. Everything seems to be working with my various browser testing. However, I'm seeing log lines in /var/log/ltm such as the following: Nov 7 08:10:33 bigip7 err tmm4[12863]: 01260014:3: Cipher 16:2 negotiated is not configured in profile /Common/MyClientSSLProfile. Nov 7 08:21:44 bigip7 err tmm3[12863]: 01260014:3: Cipher 16:2 negotiated is not configured in profile /Common/MyServerSSLProfile. Both of the above SSL Profiles utilize the "DEFAULT" cipher list. So, my assumption is that some clients are hitting this Virtual Server and are presenting a cipher that the DEFAULT cipher list doesn't include. Can anyone decode what the "Cipher 16:2" (there are others... "Cipher 4:3", "Cipher 16:3", "Cipher 4:2" etc.) notation means - is it specific to the lines you see when you issue "tmm -clientciphers 'DEFAULT'" or "tmm -serverciphers 'DEFAULT'"? I'm not sure that anything is really wrong here, but I am concerned that we might be trashing some SSL connections (doing a tcpdump of the traffic, and correlating times when the above /var/log/ltm errors get logged, then looking up the source IP address and correlating the timestamp to the Apache logfiles shows me most of these hits are to the webserver and doing a "GET /") - clearly not all SSL transactions are throwing the /var/log/ltm errors - just some. Thanks for any insight anyone may have. JoeSolved616Views0likes7Comments...has more than one clientssl/serverssl profiles that is default for SNI
I'm getting this error when applying two ClientSSL profiles to a VS. The first profile (already assigned) has 'Default for SNI' enabled, the second I'm trying to add does not. Any ideas? VE: TMOS v11.3.0 build 3138.0. I've tried removing both profiles and re-adding and disabling 'Default for SNI' in both profiles without success.529Views0likes5CommentsApplication works externally via F5 but not internally
Hi One of the application works fine when accessed externally eventhough the certificate on the server isn't correct and on F5, we have added digi cert signed certificate as client ssl profile and used as server ssl profile as the server is running https service.when accessed internally, the connection is reset and page doesn't come up. Couple points to note when accessed internally, the application is in a different domain than the one from where it is being tried but the same laptop when connected to external, the application works fine. Network wise, telnet works on 443 from internal network to application. Did packet capture and ssl handshake seems to be successful between (client and f5) and (f5 and sever) and I can see 'application data' sent but then the client resets the traffic. Not sure why the application access works externally because the certificate on the server is wrong and when access directly to server, it gives cerficate error.433Views0likes1CommentDoes using default clientssl profile disable SSL offload for the VIP?
I have a VIP that is using client ssl profile with default (localhost) certificate. my pool members for this VIP have the Certificate for this URL. I see the certificate when i access the VIP. I believe that i should receive a certificate error if SSL offloading is enabled on F5 but i dont see the error. Why is that?423Views0likes4CommentsFinding what Certificates are used by what SSL Profiles
Hi, I have a couple new certificates that will replace existing certificates on the F5. The new certificates will need to have new names and as a result the SSL profiles that use the old certificates will need to be updated. My question is, how can I identify what certificates are used by what SSL profiles? The production F5 is managed by a third party so I only have GUI access, no terminal. Thank you in advance.Solved382Views0likes2Comments
