Hello. I read on another list about how one (presumably) Linux user connects
to newsgroups using one of two different methods on the command line. If I
am not mistaken, both use telnet. The two different commands he used to
illustrate them are these:
You can use STARTTLS on the nntp port (119):
$ echo -e 'HELP\nQUIT\n' | nc news.gmane.org nntp | grep TLS
or you can connect to the nntps port (563):
$ gnutls-cli --insecure -p nntps news.gmane.org | grep 200
200 news.gmane.org InterNetNews NNRP server INN 2.5.1 ready (posting ok)
The second of these is using a program called "gnutls-cli", which is that is
available to cygwin. I have cygwin on my system and I tied using the command
at the Windows command prompt exactly like this:
gnutls-cli --insecure -p nntps news.gmane.org | grep 200
It did not work but I got an error back:
"Cannot resolve news.gmane.org:nntps: servname not supported
for the ai_socktype."
What am I missing in order to make this work? Thanks.
Cygwin creates a symlink for /etc/services ->
/cygdrive/c/WINDOWS/system32/drivers/etc/services. I don't find an entry
for nttps in /etc/services, really
WINDOWS\system32\drivers\etc\services. I do find it on Linux:
Linux:grep nttps /etc/services
nntps 563/tcp # NNTP over SSL
Cygwin:grep nttps /etc/services
You could try adding the line to /etc/services or somehow specifying
port 563 to gnutls-cli.
