nslookup works, but ping, finger, telnet, et al don't : HELP!

Post by Allan Bail » Fri, 05 Apr 1991 00:51:56



 Over the weekend I brought up and installed a Sun 4/490, SunOS 4.1.1 .

 The problem is that our named seems to not be working properly, and I can't
figure it at all.

 Symptoms:

  sendmail to off-campus sites returns complaining about "mailer world unknown"

  ping and finger say "unknown host"

  nslookup works fine.

 Question:

  Does anyone have any ideas what could be the problem?

  any help would be appreciated.

If you use NIS, you have to call "makedbm" with "b"-option in your NIS-
makefile while making "hosts.time":

hosts.time: $(DIR)/hosts

                sed -e "/^#/d" -e s/#.*$$// $(DIR)/hosts | $(STDHOSTS) \
                | awk '{for (i = 2; i <= NF; i++) print $$i, $$0}' \
                | $(MAKEDBM) -b - $(YPDBDIR)/$(DOM)/hosts.byname; \
                ...          /|\
                ...           |
                ...           |

At the top of the Makefile in /var/yp set the parameter B to be -b, ie.
B=-b

Now delete all *.time files in /var/yp and remake all your maps(remember
to delete all unwanted host names from the hosts file.  Usually a good
idea to leave local names but delete others).  Restart ypserv and also
ypbind on any clients.

Steve.

We have the same problem.  Is there any way we can resolve names without
running NIS?

1. Telnet et.al. from the same subnet won't work

Hi all,

This is very likely a FAQ, but I (we) are still making our way through the
docs and faqs.  Our lan is subnetted into three subnets.  Machines on the
same subnet as the new Linux box can not access it via Telnet, POP3, etc.,
but machines on the other subnets have no difficulity.  Any pointers to
the (likely) misconfiguration or appropriate faq will be greatly appreciated.

Thanks,
Dana
