@ -57,14 +57,6 @@ But the following OS differences result in errors on non Linux systems:
|
|||
$PATH, and "openssl s_server ..." needs enough entropy to generate a key.
|
||||
|
||||
|
||||
Q: When I specify a dual address (two partial addresses linked with "!!") on
|
||||
the command line, I get some message "event not found", and my shell history
|
||||
has the line truncated. Not even protecting the '!'s with '\' helps.
|
||||
|
||||
A: '!' is appearently used by your shell as history expansion character. Say
|
||||
"set +H" and add this line to your (bash) profile.
|
||||
|
||||
|
||||
Q: On Solaris, socat was built successfully, but when started, it gets killed
|
||||
with something like "ld.so.1: ./socat: fatal: libreadline.so.4: open failed: no
|

such file or directory"
