Summary: getaddrinfo delays
Product: Portable OpenSSH
Version: -current
Platform: Alpha
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: ssh
AssignedTo: openssh-unix-dev at mindrot.org
ReportedBy: dgp at nist.gov
This report is for version 3.4p1, which I don't find above.
(Is this still the place to report bugs in OpenSSH?)
Ever since I updated to 3.4p1, I've noticed very slow
connections using the ssh client. I finally got annoyed
enough to look into it and found that the getaddrinfo()
call in ssh_connect() is taking ~10 seconds to complete.
I read some notes that blamed this on poor IPv6 name
resolution in the GNU C library, version 2.1.2. I have
version 2.1.3, but I still followed the advice and
re-configured OpenSSH with --with-ipv4-default and
re-installed. No change. Then I went into config.h
and explicitly added
#define BROKEN_GETADDRINFO 1
No change. I hacked in some extra debug() calls to
verify that I am indeed passing hints.ai_family = AF_INET
into the getaddrinfo() call, but I still see 10 second
delays. Is this really a glibc problem? Or a system
mis-configuration? What can I do about it?
