SSH v1 on IGLU disabled

[Ilya Konstantinov]

Hi,

I disabled support for SSH v1 on IGLU, following the suggestion of
BeyondSecurity's automated scan (BTW, thanks Aviram!). If you don't
have an SSH v2 client yet, you can get OpenSSH for Unices and PuTTY
for Win32, both free and both support SSH v2.
