<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">since the last CentOS8 release update I have a problem with jailed SFTP connections "Chrooted SFTP, SCP and RSYNC" on a server with CentOS8/BO 5210R.<o:p></o:p></p>
<p class="MsoNormal">No connection is established. The SFTP client asks if there is a SFTP server on the other side.<o:p></o:p></p>
<p class="MsoNormal">SFTP connections of users with unlimited shell access are no problem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Yes, the server was restarted. Yes, the jailkit.service is running.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is an excerpt from the connection log:<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:14 orbital7 systemd-logind[1654]: New session 130 of user detest.<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:14 orbital7 systemd[1]: Started Session 130 of user detest.<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:17 orbital7 jk_chrootsh[25727]: path /home/.sites/site6/home/./users/detest is setgid<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:17 orbital7 jk_chrootsh[25727]: path /home/.sites/site6/home/./users/detest is group writable<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:17 orbital7 jk_chrootsh[25727]: now entering jail /home/.sites/site6/home for user detest (1156) with arguments -c /usr/libexec/openssh/sftp-server<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:17 orbital7 jk_lsh[25727]: jk_lsh version 2.20, started<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:17 orbital7 jk_lsh[25727]: executing command '/usr/libexec/openssh/sftp-server' for user detest (1156)<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:18 orbital7 systemd-logind[1654]: Session 130 logged out. Waiting for processes to exit.<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:18 orbital7 systemd[1]: session-130.scope: Succeeded.<o:p></o:p></p>
<p class="MsoNormal">Dec 9 10:06:18 orbital7 systemd-logind[1654]: Removed session 130.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This does not necessarily look like an error message to me.<o:p></o:p></p>
<p class="MsoNormal">I have not found any other logs or error messages.<o:p></o:p></p>
<p class="MsoNormal">As written, I set the user to "unlimited shell access", then it works.
<o:p></o:p></p>
<p class="MsoNormal">But the "Chrooted SFTP, SCP and RSYNC" does not work.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone understand this? Are there any ideas? Is there a fix for it?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best regards,<o:p></o:p></p>
