Hi, it maybe could be an issue with the dns resolver.
If the dns entries are not resolvable, it could take longer to connect with ssh to your server.

Could you elaborate on the term "slow connections".
Is the etablishion of a connection slow, or did you get slow transfer rates from ... to ssh.

cheers ...

check /etc/resolv.conf
Did you have a system without such this problem, then compare
Is the IP your are trying to connect available in /etc/hosts
Check your etc/nsswitch.conf file
hosts: files dns
ipnodes: files dns
Should have entries in above orders.
Are there problems with your main dns server in case that the second dns server answers your dns queries?
What says the /var/adm/syslog/syslog.log about your problem . Check it!

desproxy-dns

desproxy-dns(1) 						   User Commands						   desproxy-dns(1)

NAME

       desproxy-dns - DNS for dynamic connections

SYNOPSIS

	  desproxy-dns dns_server proxy_host proxy_port

OPTIONS

       None

DESCRIPTION

       If you have direct DNS access then you don't need to do anything else.  You know you have direct DNS access if you can resolve host names
       to IP addresses.

       NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if
       you are running UN*X, you actually have to run desproxy-dns as root).

       OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network
       accordingly (again, need to be root in UN*X).

       Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works.

ENVIRONMENT

       None.

FILES

       None.

SEE ALSO

       dnsproxy(1), ping(1)
