Hi Hinko,
I have recompiled the kernel and enabled the PTY :
Device Drivers ->
character devices ->
Legacy (BSD) PTY support [*]
Max. number of legacy PTY in use (256)
I have reloaded the linux kernel and started the telned
but I have the same messages printed on the screen:
Connected to ml403-mirek.pss.ch (129.128.107.50).
Escape character is '^]'.
Connection closed by foreign host.
I do not know if it is somehow related to the password configuration files:
It seems to be something not set correctly:
I have tried to change the password for user root:
passwd
passwd: uknown uid 0
passwd mirek
passwd: uknown uid 0
when I inoked
/bin/login
ml403-mirek login: mirek
login: no valid shadow pasword
Maybe the password issue is the source of the problem that telnet does not
start.
The config files in the /etc directory look like that:
ls /etc
fstab group gshadow inetd.conf init.d passwd services
cat fstab
devpts /dev/pts devpts defaults 0 0
cat group
root:x:0:root
sls:x:1:mirek
cat gshadow
root:::root
sls:!::
cat inetd.conf
23 stream tcp nowait root /usr/sbin/telnetd telnetd -l /bin/login
cat passwd
mirek:x:500:500:Linux User,,,:/home/mirek:/bin/sh
cat services
.
.
.
# 21 is registered to ftp, but also used by fsp
ftp 21/tcp
ftp 21/udp fsp fspd
ssh 22/tcp # SSH Remote Login Protocol
ssh 22/udp # SSH Remote Login Protocol
telnet 23/tcp
telnet 23/udp
.
.
.
I have also tried to execute telnet daemon like that:
telned -l /bin/sh
but the result is the same as previously
Best Regards
Mirek
