rlogin doesn't work

[Ionut Grigorescu_2]

Hi,

I cannot use rlogin on the NIS server. On the others machines it works fine, but on the server I receive an error from rlogind:
Host address mismatch, see the attachment with the print-out of /etc/hosts and ypcat hosts command.

Thanks in advance

Hi

On the NIS server and the machine where you wish to rlogin from do you get the same result for.

nslookup hostname(server)
nslookup ip(server)
nslookup hostname(sourcemachine)
nslookup ip(sourcemachine)

This is a name resolution problem and this should show it

I try to rlogin from nmsgprs1 to nmsmd (rlogin doesn't work from nmsgprs1 to any other station). These are the results on nmsgprs1:

I cannot see the problem (maybe because I'm a beginner...:-

Maybe name service problem. Try this:
If /etc/nsswitch.conf exists,please modify it directly:
...
hosts: nis files dns
...
-----------------------
If /etc/nsswitch.conf doesn't exist, please do:
#cp -p /usr/newconfig/etc/nsswitch.conf /etc/
and modify it as above.

Hi

For me it gets confused here

# nslookup 10.1.32.12
Default NIS Server: nmsgprs1.comlan.viag-interkom.de
Address: 10.1.32.12
Aliases: nms1, nmsgprs1

Trying NIS
Name: nmsgprs1.comlan.viag-interkom.de
Address: 10.1.32.12
Aliases: nms1, nmsgprs1

# nslookup 10.1.33.12
Default NIS Server: nmsgprs1.comlan.viag-interkom.de
Address: 10.1.32.12
Aliases: nms1, nmsgprs1

Trying NIS
Name: nmsgprs1
Address: 10.1.33.12
Aliases: nmsgprs1_of_lan1


33.12 has as name an alias of 32.12 and taht is against the logic of this

OK, I have seen now. Any suggestions to correct that - I'm not sure what is the impact of a change on other parts of the system. I use for example for backups a Omniback server which maybe use the aliases/names to contact the hosts..

Folks,

A common issue with `rlogin` is ESCAPE characters in the ~/.rhosts (or hosts.equiv) file(s). Even when you can reduce your issue to reviewing the simple case of only /etc/hosts and ~/.rhosts, with no resolv.conf (or nsswitch.conf) files and you still have rlogin issues---->
(a) mv ~/.rhosts ~/.rhosts.orig
(b) vi ~/.rhosts {be careful with typos and escape sequences)

Cheers,

Bryan
