Hello. We found this little issue with curl:

Timeout setting with -Y and -y options doesn't work with sftp protocol.

curl --version
curl 7.21.2 (i686-pc-linux-gnu) libcurl/7.21.2 OpenSSL/0.9.7a
zlib/1.2.1.2 libidn/0.5.6 libssh2/1.1 Protocols: dict file ftp ftps
gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp
smtps telnet tftp Features: IDN IPv6 Largefile NTLM SSL libz

Error reproduction:
install a sftp server, and use curl as such:

curl -y 10 -Y 1 --connect-timeout 10 -o /dest/file -m 1200 -u
user:password sftp://server//from//file.txt

unplug the network cable: no timeout.

note: when transfering the same file via http, timeout works.
