SSL_get_rbio(3SSL) OpenSSL SSL_get_rbio(3SSL)NAME
SSL_get_rbio - get BIO linked to an SSL object
SYNOPSIS
#include <openssl/ssl.h>
BIO *SSL_get_rbio(SSL *ssl);
BIO *SSL_get_wbio(SSL *ssl);
DESCRIPTION
SSL_get_rbio() and SSL_get_wbio() return pointers to the BIOs for the read or the write channel, which can be different. The reference
count of the BIO is not incremented.
RETURN VALUES
The following return values can occur:
NULL
No BIO was connected to the SSL object
Any other pointer
The BIO linked to ssl.

SSL_set_fd(3SSL) OpenSSL SSL_set_fd(3SSL)NAME
SSL_set_fd - connect the SSL object with a file descriptor
SYNOPSIS
#include <openssl/ssl.h>
int SSL_set_fd(SSL *ssl, int fd);
int SSL_set_rfd(SSL *ssl, int fd);
int SSL_set_wfd(SSL *ssl, int fd);
DESCRIPTION
SSL_set_fd() sets the file descriptor fd as the input/output facility for the TLS/SSL (encrypted) side of ssl. fd will typically be the
socket file descriptor of a network connection.
When performing the operation, a socket BIO is automatically created to interface between the ssl and fd. The BIO and hence the SSL engine
inherit the behaviour of fd. If fd is non-blocking, the ssl will also have non-blocking behaviour.
If there was already a BIO connected to ssl, BIO_free() will be called (for both the reading and writing side, if different).
SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only for the read channel or the write channel, which can be set
independently.
RETURN VALUES
The following return values can occur:
0 The operation failed. Check the error stack to find out why.
1 The operation succeeded.

I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)

I've "installed" LM 19.1 to a PNY 16Gb(2.0) pendrive. I have a few issues that I'd like to resolve. First and foremost, the O.S. experiences "lagging" issues and to a lesser degree, freezing.
