我正在尝试将文件压缩到Synology NAS(进入/ tmp目录)中。从我的Ubuntu计算机的命令行执行此操作可以按预期进行。运行PHP代码可以在常规Linux发行版上正常运行(就像我尝试过的每个发行版一样-Ubuntu，Debian，Centos，Redhat，Suse，Arch)。即使与其他* nix兼容(MacOS，AIX等)也可以。我不认为这是PHPSecLib的问题，但这就是我们正在使用的问题。 Ubuntu 18.04至运行DSM 6.1.7-15284的Synology DS3615xs。凭据正确。用户对/ tmp具有写权限。我已经发布了完整的日志(这是未使用的测试Synology)。任何帮助将不胜感激。
如果我从Ubuntu机器的 shell 运行scp，则会得到以下日志，并且可以按预期运行。

最佳答案
似乎DiskStation 确实使您陷入了chroot。根据https://forum.restic.net/t/new-user-sftp-issues/165
And sftp also puts you in your home directory, but in a chroot environment where that directory is at the root and you can’t leave.
mark@desktop:/$ sftp mark@192.168.1.22
mark@192.168.1.22's password:
Connected to 192.168.1.22.
sftp> cd /tmp
Couldn't stat remote file: No such file or directory
sftp> pwd
Remote working directory: /
