do it again and compare your "env", "aliases", and login "profiles" and you will find them different.

Hi Jack,

Can you do ls ? if yes -> check your alias.

sir,

ls is okay. But ll be hanged.
and I got information by alias....

autoload='typeset -fu'
command='command '
functions='typeset -f'
history='fc -l'
integer='typeset -i'
local=typeset
nohup='nohup '
r='fc -e -'
stop='kill -STOP'
suspend='kill -STOP $$'
type='whence -v'

How to verify these information is correct?

Hi,

Check th permission of ll
-r-xr-xr-x 7 bin bin 32768 Sep 29 1999 /usr/bin/ll

Try the following

# command /usr/bin/ll

It could possibly be a NIS problem. Does you server use NIS? ls does not need any file attributes, yet ls -l needs to show user and group info. If the NIS server is not responding ls -l could hang.

Hi Jack,

This is indeed most interesting!!!

Why should ls -lrt work in a telnet session but not in a rlogin session while ls works in both telnet and rlogin sessions?

The more far-fetched reason I can think of is that either your rlogin binary or your login shell on the remote server has been hijacked (i.e. rootkit'ed) to "hang" upon recognising ll from a rlogin session. However, this doesn't make much sense as to why on earth would someone do that i.e. why not "rootkit" all sessions including telnet sessions as well instead of just rlogin sessions?

Please post up the cause when you do find out the reason. Thanks in advance. Regards.

Do you login to a nfs-mounted home-directory?

We had various problems with these (login did not show prompt, ll hang, ...) until we patched NFS on server and client side.
Problems were related to NFS file-locking mechanism.

All,
we already solved this problem. I disable NFS server and client starup on file /etc/rc.config.d/nfsconf

NFS_CLIENT=0
NFS_SERVER=0

AUTOMOUNT=0

Hi Jack,

Did you find out why ls -lrt should work in a telnet session but not in a rlogin session while ls works in both telnet and rlogin sessions?

Thanks in advance. Regards.

When I change back the paramaters, this problem still there. Here, I gather some information....

1. ls -lrt failed either telnet or rlogin...
2. only ls -lrt failed when I issue this command on / directory.
3. on /etc/mnttab include one entry "galaxy:(pid880) /net ignore ro,intr,port=631,map=-hosts,indirect,dev=0000 0 0 10
27319472"

Hi Steven,
Here, have some test phase as following,

1. /tmp> ls -lrt (okay)
/> ls -lrt (hang up)

2. diable automount on /etc/rc.config.d/nfsconf --- ls -lrt (okay)

3. check /etc/nsswitch.conf not existing. Correct this file.

4. /tmp> ls -lrt (okay)
/> ls -lrt (okay)

Bingo!!!! ls -lrt okay on anywhere....

Jack Fan
