If You receive the error something like, despite the scp exist:
|
|
nsc-book:~ nsc$ scp root@loginroot.com:/root/filename ~/filename bash: scp: command not found nsc-book:~ nsc$ which scp /usr/bin/scp |
It may look silly, but please check if the destination server has that package too ;) I haven’t expected a CentOS server not having this simple package by default. Anyway, on CentOS it’s in openssh-clients package, and may be installed with command:
|
|
yum install openssh-clients |
Of if it exists there too, please check the PATH variable on the remote system, if it shosw the correct ipaths. Also, You may check .bashrc on remote user if it tries to overwrite the PATH value.

root@server:/tmp# git clone https://git.kolab.org/diffusion/RPK/roundcubemail-plugins-kolab.git Cloning into 'roundcubemail-plugins-kolab'... error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none while accessing https://git.kolab.org/diffusion/RPK/roundcubemail-plugins-kolab.git/info/refs fatal: HTTP request failed |
The fix: Append CA root of that cert to file: /etc/ssl/certs/ca-certificates.crt

Previous part: Part 1 – Cracking the RSA keys (Part 1 – getting the private exponent) PART 2 For a private key generation, we need to create an asn1parse.txt file with the contents of:

The whole idea of the RSA private key is the hardness of factorisation of two very large prime numbers. That’s why recommended RSA keys are >2048bit long. I won’t get into RSA details itself. If You need any info, it’s here: WIKI For a sake of demonstration, 256bit public_key will be used. With the current hardware that we have these days, it’s very easy crackable.

Lets convert it to a more ‘mathematical’ expression:

Directadmin doesn’t have possibility to add SSL certificate for a subdomain, unless You add it as a separate domain in domain control. You may also use separate SSL certificates by creating a custom httpd (or nginx, but it would require to change the CAROOT line) file in user configuration dir i.e. loginroot.com.cust_httpd (or loginroot.com.cust_nginx if it’s nginx).

That’s because cloudlinux developers modified their lsapi code, and didn’t add variable default value. Very nice guys… The fix:
