Disk space full - what files, folders are safe to delete?
Hi I've searched Dev Central for help with clearing disk space. I am happy to use bash as I have now figured out how to display files within var/log directory and use the "rm" command to remove files. I can see the files within the var/log I have read articles about maintaining disk space. I have deleted ucs, software images. These files are at ".1 or .2.gz" 0 or not even on any of the F5 var/log directories /dev/mapper/vg--db--vda-dat.log 2.9G 2.9G 0 100% /var/log /dev/mapper/vg--db--vda-dat.share 15G 5.4G 8.5G 39% So far I have the above. What files are safe to delete from the /var/log or any other directories? Or can I delete file contents silently without affecting performance or service? What would be good bash commands to rm or clear files/ folders?Open Redirection Mitigation
hello, ASM has a feature to mitigate the open redirection attacks when the redirect happens at the header level (i.e: with Location in response). When the redirection is within the payload response, the ASM does not block it. do you guys know about any ASM configuration that may address this issue and mitigate this kind of attack ? thanks. o.

Hello, I am learning F5 and I have searched through many of posts. I really need to under how the f5 works. When i load up my f5 in cli - i see this (cfg-sync In Sync) (Active) (/Common) (tmos)# I want to run this command df -h it is always an invalid argument. I have an error and I need to clean up disk space, systemd-journald[438] Failed to create new user journal: No space left on device I would like to free up disk space to get the f5 in working order again, any help on this and commands will be a great help. Thank youCan iRule be used to perform exception of IPI category based on Geolocation
Hi Everyone, Can we configure iRule to perform exception on certain IPI category like "Spam Sources" based on Geolocation. For instance, I want to bypass the mitigation enforced on "Spam Sources" IP intelligence category for "Nepal" -Geolocation specific because of the large false positives on this category. I found the iRules to enforce the mitigation based on the defined IPI category: when HTTP_REQUEST { set ip_reputation_categories [IP::reputation [IP::client_addr]] set is_reject 0 if {($ip_reputation_categories contains "Windows Exploits")} { set is_reject 1 } if {($ip_reputation_categories contains "Web Attacks")} { set is_reject 1 } if {($is_reject)} { log local0. "Attempted access from malicious IP address [IP::client_addr] ($ip_reputation_categories), request was rejected" HTTP::respond 200 content "<HTML><HEAD><TITLE>Rejected Request</TITLE> </HEAD><BODY>The request was rejected. <BR> Attempted access from malicious IP address</BODY></HTML>" } } https://techdocs.f5.com/en-us/bigip-15-0-0/big-ip-local-traffic-manager-implementations/enabling-ip-address-intelligence.htmlLDAPS and renegotiation
Hello, hope everyone is well! we have a requirement to present 2 different issuer/signed certificates based on the incoming client IP. I am pretty sure from an HTTP perspective I would do something like this when CLIENT_ACCEPTED { if {([class match [IP::client_addr] eq signer_list_of_client_A_IPs]) } { SSL::profile cert_with_issuer_type_A } else { SSL::profile cert_with_issuer_type_B } } when HTTP_REQUEST { SSL::renegotiate } Question I have is whether this would work for LDAPS clients and how (if needed at all) the renegotiation step would be achieved, given that the HTTP_REQUEST will not be available. Many thanks Jon
Need help on i-rule to specific uri path
Hello All, I'm working on an i-rule that I need to do the following; given a set of specific source ip addresses, only allow access to specific uris of /ws/rest/external*. I set the specific source addresses in a data group, referencing the data group. When I apply this i-rule to the virtual server, on testing I get an Insecure HTTPS message. I am on version 15.8.1.2. We plan to upgrade to most stable release on 16 soon. Any suggestions on what I can do with the i-rule posted below? Thanks in advance. when CLIENT_ACCEPTED { if { [class match [IP::client_addr] equals Boomi_external] } { pool esd-bmapi-dc1-as01-f5.lanl.gov_8077_pool } } when HTTP_REQUEST { if ![HTTP::has_responded] { if { ([HTTP::host] equals "apigway-d.lanl.gov" or [HTTP::host] equals "apigway-d.lanl.gov") } { if { [HTTP::uri] starts_with "/ws/rest/external* " || [HTTP::uri] starts_with "/ws/rest/external*" } { pool esd-bmapi-dc1-as01-f5.lanl.gov_8077_pool } else { reject } return } } }
Stable Firmware for F5
Hi All, Currently we have f5 BIG-IP i5600 appliance in our environment. The current firmware version is 15.1.10, we are planning to upgrade the firmware to the n-1 patch or next stable version. I'm new to F5. Can anyone suggest an stable version or guide how to check for the feasible firmware version. The main feature that we use in F5 is Load balancer and we enabled ASM policies for the VIPs. So there should not be any impact on the existing function. Thanks in Advance. Karmegha Kuzhali.F5 VE in Azure - troubles with Sentinel integration
Hi! I'm having F5 Act/Stb cluster - 2 VMs in Azure with 2 traffic interfaces only (external, internal). I use BIG-IP 16.1.3 build 0.0.12 I'm trying for the first time in my life integrate it with Sentinel and so far I fail to do it succesfully. When following this article:https://my.f5.com/manage/s/article/K85539421point by point: Install telemetry extension goes well. I have 1.32.0 build 2 version (downloaded today). curl check is succesful Create iRule - done Create a pool to handle telemetry traffic - ends up with down by monitor. (Manual suggests to use tcp monitor). I tried to support with hints from: https://community.f5.com/t5/technical-articles/deploying-big-ip-telemetry-streaming-with-azure-sentinel-as-its/ta-p/278738, where people suggest to add static route the via internal vlan: net route telemetry { description "Allows monitor to work" interface /Common/internal network 255.255.255.254/32 or changing port lockdown mode: "One more note: the self IP on the chose VLAN you're using for routing the 255.255.255.254 traffic needs to allow TCP 6514, either by setting the "port lockdown" to NONE or adding a custom port." I tried to finish the manual, so: Create a virtual server to listen for Telemetry traffic Create a request-log profile Attach the request logging profile to the virtual server And when it comes to deploy the declaration (which I do via curl with .json file, I get: Has anyone passed through some manual integrating F5 with Azure Sentinel succesfully? Or maybe I'm doing here some obvious mistake? Thanks in advance for your help
