https://community.cisco.com/t5/network-access-control/acs-linux-shell/m-p/2519195#M7397 <P>Over the last month, we've been having some major issues with our ACS.&nbsp; For no apparent reason, it just quits accepting RADIUS/TACACS requests.&nbsp; As you can imagine, our wireless users, as well as our network admins can't sign into wireless, or onto the network devices, due to this.&nbsp; It seems as though the processes fail.&nbsp; I can't even log into the ACS CLI to see which processes fail.&nbsp; The only way around this is to log into the vSphere client, power off the ACS instance, and then power it back on.&nbsp; I'd like to log into the shell, to see if we're having file system issues with directory sizes, etc.&nbsp; How can I log into the shell, from the CLI, to see the directory structure?&nbsp; I remember when I was upgrading from 5.2.x to 5.3.x, I was able to get into the shell, but can't for the life of me remember how.&nbsp; Can anyone shed any light on this?&nbsp; Thanks!</P> Fri, 21 Feb 2020 18:29:26 GMT Dan Man 2020-02-21T18:29:26Z https://community.cisco.com/t5/network-access-control/acs-linux-shell/m-p/2519195#M7397 <P>Over the last month, we've been having some major issues with our ACS.&nbsp; For no apparent reason, it just quits accepting RADIUS/TACACS requests.&nbsp; As you can imagine, our wireless users, as well as our network admins can't sign into wireless, or onto the network devices, due to this.&nbsp; It seems as though the processes fail.&nbsp; I can't even log into the ACS CLI to see which processes fail.&nbsp; The only way around this is to log into the vSphere client, power off the ACS instance, and then power it back on.&nbsp; I'd like to log into the shell, to see if we're having file system issues with directory sizes, etc.&nbsp; How can I log into the shell, from the CLI, to see the directory structure?&nbsp; I remember when I was upgrading from 5.2.x to 5.3.x, I was able to get into the shell, but can't for the life of me remember how.&nbsp; Can anyone shed any light on this?&nbsp; Thanks!</P> Fri, 21 Feb 2020 18:29:26 GMT https://community.cisco.com/t5/network-access-control/acs-linux-shell/m-p/2519195#M7397 Dan Man 2020-02-21T18:29:26Z
