Hi !

The Internet Manager interface is well known to screw the

        /etc/resolv.conf

file up; in fact, if you look at it, you should see something
similar to

        hostresorder local bind
        nameserver 0.0.0.0

Of course, the IP is not that good and so the "resolver" routines
time out while contacting the "fake" name server machine.

If you're NOT using a DNS box, either remove or rename the above
file.

The reasons behind the telnet which slows down during the login phase
is due to the fact that the telnetd server tries a reverse-lookup
of the incoming machine IP address; if you have a badly configured
DNS configuration, this procedure fails after a timeout.

Hope this helps !

Best,
Roberto

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
