Lost Access to GUI - VM
Hi everyone, Hoping to get some help.I have a little test machine GTM/LTM on a trial license which I use to practice and test out deployements on.I've been using it for a good month running off of vmware workstation.It's been working flawlessly until today.I typically shut it down when not in use.When I attempted to use it today, for some reason, I canot access the GUI.I simply get "this site can't be reached". x.x.x.x refused to connect. I'm able to log on to the box through the terminal and putty (ssh).I checked the config to ensure that everything is still in tact, and it is. I'm able to ping and access the mgmt interface, and obviously as I'm ssh'd in to it, the config looks fine and identical to how I left it the previous time I used it. At bootup, the system goes in to INOPERATIVE state. There are a few startup messages: kernel: ibrs changed from 1 to 0 EXT4-fs error (device dm-1): ext4_mb_generate_buddy:757: group 17, block bitmap and bg descriptor inconsistent: 23131 vs 23132 free clusters Re-starting named After the re-starting of named, it changes from INOPERATIVE to Active. I have tried restarting the box and virtual machine multiple times.I tried restarting tomcat and httpd processes.I get the following message when restarting httpd httpd[11494]: [ssl:emerg] [pid 11494] AH01874: Could not initialize session cache. Exiting. I typically use chrome, but tried mozilla, same issue. Anyone have any ideas on a fix? Thanks
Failing to login to GUI with admin account
I'm experiencing a really strange issue with my Virtual F5 LTM. I'm running BIG-IP 11.6.1 Build 1.0.326 and since two weeks I'm not able to log into the GUI anymore. Neither with the admin account, nor with any other account. The CLI is no issue, I can log in there without any problems. I keep seeing the follow logs in de secure.log: Nov 10 21:09:37 localhost alert httpd[20065]: PAM Couldn't open /var/log/pam/tallylog : Permission denied Nov 10 21:09:37 localhost alert httpd[20065]: pam_tally2(httpd:auth): Error opening /var/log/pam/tallylog for update: Permission denied Nov 10 21:09:39 localhost info httpd(pam_audit)[20065]: User=admin tty=(unknown) host=10.128.1.1 failed to login after 1 attempts (start="Thu Nov 10 21:09:37 2016" end="Thu Nov 10 21:09:39 2016").

Not sure if it's related, but I find it strange that PAM couldnt open the tally log. The file is definately there and permissions seems to be correct. Things I've tried so far without result: resetting the admin password to default creating a new user account with admin rights loading default config set full rights to the tallylog file. uploaded the config to iHealth, no really strange things beside a load of failed loging attempts tried different browsers. Maybe someone else has any suggestions what to do next? I'm kinda stuck now... Thanks in advance.DNS Tab not appearing on device
Hello, I am encountering an issue where the DNS tab is not showing up in the management GUI. I have the DNS module licensed and provisioned but the DNS tab disappeared after provisioning. I have tried rebooting the system, de-provisioning and re-provisioning all modules, and restart certain daemons. Has anyone else encountered this issue or can anyone provide possible solutions?
Web UI search for objects that do NOT contain a word
In the BigIP web user interface. How do I do a search where I look for objects that dont have a word in the name. For example, how do I do a search in Local Traffic > Virtual Servers > Search field box > search for all objects that do NOT have the word 'test' in the object name?
Best tools for network toubleshooting?
Hi, I am looking for any hints about tools used by more experienced members here. I am not hard core network geek so GUI based tools are proffered (and freeware) - for Windows and Linux platforms. What I already know and use: Wireshark - pretty obvious :-). I am using F5 plugin but wonder what other plugins are really useful in real life work? Ostinato - seems to be very nice packet replay and crafting tool - will have to figure out how to replay captured traces but even without this knowledge it's very promising Network Emulator Toolkit (Windows) - seems that it would be great for simulating different type of links (like changing RTT, packet loss, etc.) - just installed it and have no chance to play around. TCP/IP Builder (Windows) - simple yet very useful tool to play with TCP/UDP connection setup netem (Linux) - exception from my own rule - command line tool - but seems to be quite powerful in the same area as Network Emulator Toolkit Piotr
Default view of "Local Traffic Network Map" has changed and wont go back to normal
I am using an HA pair of F5 Big-Ip 3900's on version 11.3 build 3144.0 HF8. I was working in the GUI and noticed that when trying to go to the Local Traffic/Network Map the view had changed to "Local Traffic Summary" and will not go to the map unless clicking on the "Show Map" button. I made sure that under system/preferences/start screen it was still set to "Network Map", and it was... I have even changed the preferences to something else, which worked ok, but when I went back to the preferences setting of "Network Map" and you hit the RED F5 ball in the upper left corner of the GUI it still goes to the "Local Traffic Summary". does anyone know where this might be found in a config file in the command line environment? it's getting really frustrating..Long time to show up virtual server list in gui
When choosing from GUI: Local Traffic ›› Virtual Servers : Virtual Server List - the list shows up after 20 sec, what is a very long time. There is no such problem when showing other lists/parameters. The big-ip was upgraded to 12.1.2 and was configured a new. It seems that some old configuration bits are messing up, but I can't nail it. Any idea how to correct it ?
