[Patch] Proxy command-line argument
Hi,
I made a small patch to setup.exe. It adds the following command line argument:
-p --proxy HTTP/FTP proxy (host:port)
The only modified file is net.cc, which is attached to this mail.
Basically, the modifications are:
- Inclusion of sstream and getopt++/StringOption.h
- Addition of static StringOption ProxyOption (, 'p', proxy,
HTTP/FTP proxy (host:port), false);
- Modification of NetPage::OnInit () method to modify
NetIO::net_method , NetIO::net_proxy_host and NetIO::net_proxy_port
I think my changes are conformed to the Cygwin coding guidelines and I
hope to see this patch accepted.
As it is my very first patch, I'm not sure if I must send it to this
mailing-list; or to the cygwin-patches one ?
Thanks in advance for your comments.
Vincent

RE: ssh interactive shell not working
If I leave out the -k, I get no prompt but I am in, I can run commands, etc. I was meaning the -i I search the entire computer and only found the one bash.exe, in the existing cygwin home Here are my cases: 1) If am on the ssh server itself, all works fine, I can logon via ssh localhost or ssh myhost. Get prompt and all looks good. 2) If I logon to the ssh server from any other machine with bash -i, ssh myhost bash -i, all works fine, I get a prompt and can run commands 3) If I logon to the ssh server from any other machine the normal was, ssh myhost, it closes connections right away 4) If I logon to the ssh server from any other machine to just run a command, it works fine. The command runs on ssh server and shell comes back ssh myhost ls -lart ssh myhost hostname 5) If I logon to ssh server from another computer behind the router, some subnet as server, using the server private ipaddress, 192.168.1.125, still get same issue. So it is not a router issue. It appears the issue is something to do with running the bash shell by default, it just does not for some reason. I thought something was messed up with the cygwin config/install, so I deleted the dir and installed from scratch.

I noticed that my group file only had groups from the domain not local groups. I then append all the local groups to the /etc/group file, and BAM, everything works. mkgroup -l /etc/group Thanks for everyone that gave suggestions, I learned a lot about debugging ssh and cygwin.
