Poor performances when scanning hosts.equiv

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I saw 30s delay when doing remote commands (don't
blame me, I haven't the choice now) between ~ 200
servers with slow links (75kb/s), and 4 DNS.

When a server do a remote command on an other, if its
position in the hosts.equiv is deep, and the DNS is
not on the target LAN, it is slow.

Having done a tcpdump on the target, I saw numerous
DNS requests.

In fact, the problem is that the names in hosts.equiv
are resolved to IPs.
In the function __checkhost() (file pam_rhosts.c)

But Why ?
We have both names, and we could compare them...
Is there a good reason to compare IPs ?

It looks like it's done like this on SCO OpenServer
and HP-UX.
