      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Yes, the config of SSHD was slightly changed to allow the use of certain less secure ciphers. &lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi thanks for your logs.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Just on august 08th there's around 100 ssh connection initiated by these 2 IPs :&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;10.1.36.58&lt;/P&gt;&lt;P&gt;10.33.158.183&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Is there a script running or something like that ? Because the following commands are launched every 15min along the night and day and it creates SSH connections... :&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-family: courier new, courier;"&gt;2019-08-08T00:20:22Z sshd[133943]: User 'root' running command '/opt/lsi/storcli/storcli show J'&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-family: courier new, courier;"&gt;2019-08-08T00:20:22Z sshd[133943]: User 'root' running command 'ls /opt/lsi/storcli/storcli'&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-family: courier new, courier;"&gt;2019-08-08T00:20:22Z sshd[133943]: User 'root' running command '/opt/lsi/storcli/storcli /c0 show J'&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;You can correlate every time those commands are launched (in auth.log) it add an entry to shell.log, and there's exactly the same time..&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Yes. We are polling the server every 15 minutes (through SSH) from two different pollers to query the storage status (the storcli utility). We execute the script and then close the SSH connection. I don't see any evidence in the system that any of these connections is hung.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Yeah that's weird...&amp;nbsp; you start and end a ssh session it's logged so we can trust the connection close well.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Have you tried to set a timeout for ssh sessions ? (even though the starting/ending of your ssh sessions are logged so it means they close well, we can verify if a timeout change anything.)&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
