[Bug 2250] New: SOCKS5 should return "NO ACCEPTABLE METHODS" instead of nothing
https://bugzilla.mindrot.org/show_bug.cgi?id=2250
Bug ID: 2250
Summary: SOCKS5 should return "NO ACCEPTABLE METHODS"
instead
of nothing
Product: Portable OpenSSH
Version: -current
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5
Component: ssh
Assignee: unassigned-bugs at mindrot.org
Reporter: guenter at weheartwebsites.de
In:
http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/channels.c?rev=1.332;content-type=text%2Fplain
Search for: "SSH_SOCKS5_NOAUTH not found"
If a connection to SSH-SOCKS5 is established and a unsupported auth
method is sent, SSH will not reply anything.
According to http://tools.ietf.org/html/rfc1928 the server could (it
does not state if the server MUST or SHOULD, hence "could" ;) ) send
simply X'FF' NO ACCEPTABLE METHODS - with this a client can do
appropriate handling.
Would like to hear your thoughts if I am misinterpreting rfc1928, or I
should just suck it up and handle cases like this with my client.

My reading of RFC1928 agrees with yours. I'll take a look at this
after the upcoming 6.9 release is out the door.

Will the buffered bytes be sent even when the method returns -1 which
causes the caller to call chan_mark_dead(); ?
