Applies to: Centrify-SSHD 7.2p1 - 7.6p1 Description: When scp/sftp any file larger than 1GB, it stop at 1023MB with the following host key verification error: ========== [trust1@red7 ~]$ scp /tmp/Centrify-Suite-2018-mgmt-win64.zip red5.trust.domain:/tmp Red Hat Enterprise Linux Server release 5.7 (Tikanga) Kernel 2.6.18-274.el5 on an x86_64
Root cause: This is OpenSSH bug in GSSAPI key exchange that it failed to validate the host hence restricted the limit to 1GB. As Centrify-sshd is based on openssh, hence we are seeing the same problem as openssh.
Workaround: Turn of GSSAPI key exchange. Edit /etc/centrifydc/ssh/sshd_config, set the below to no >GSSAPIKeyExchange no After the above, restart Centrify-SSHD daemon # /etc/init.d/centirfy-sshd restart
Resolution: It will be fixed in the next release of centrify-sshd, in release 18.8.
