Can't telnet at my client machine using NIS(YP)

Hello Everybody...

I'm trying to set up nis(yp) on ALzza Linux release 5.0-kr(Patch Man II)

and success it...

                        ----    nis(yp) layout     ----
                        root server    ----- node08
                        client ---- node09,node10,node11

but I cannot access client Machine using Telnet...
on the other hand, I can access client Machine using other utilities,
example ftp, X-manager..

If I'm try to access on client Machine, I get the following messages

ALzzA Linux release 5.0-kr(Patch Man II)
Kernel 2.0.32 on an i686
login: jwchoi

Cannot  make/remove an entry for the specified session
                                  ------- what's mean and how to solve

Anyone seen this behavior before?  Any info would be much appreciated.

and... What is YP homepage Url ???

although following instructions in NIS-HOWTO and reading all FAQ's i could
find, i'm still not able to login to my linux machines using


the funny thing is, i can do 'ypcat passwd' and even change users passwords
with yppasswd ... but a normal user isn't able to login! might there be a
problem with these packages in conjunction with the shadow password system?
i only found hints, that it isn't that easy ...

i got 4 linux machines, one is running as the master, the 3 others as
slaves. this part works. the 4 communicate and exchange datas ...

the master is running ypserv and yppasswdd, the three others ypserv and

what could be wrong? why can i change my password as a user (when su'ing
from root) but not login ?

thanx in advance for any hints,
