Hi all,
1. I'm getting the following error when trying to access ftp server (bftpd) from ftp client (lftp)

2. Is lftp the only ftp client available on core?

I'm not sure what the question is, how to enable anonymous logins, or how to log in with lftp?
The standard "ftp" client is part of inetutils.

Thanks curaga for your response. Both. The goal is to able to access ftp server, with anonymous logins
The standard "ftp" client is part of inetutils.
But standard ftp is not there. That's the reason why I installed lftp
tc@box:~$ ftp
-sh: ftp: not found
tc@box:~$

Hi
tce-load -wi inetutils

Remove the "deny_login" line.

Hi
tce-load -wi inetutils
I didn't know it has to be installed. Thanks Misalf. "Normal" ftp client is working now. I guess I can remove lftp.
tc@box:~$ tce-load -wi inetutils

It works! Thanks curaga :)

I've the following config set on /opt/bootlocal.sh
ifconfig eth0 10.1.0.1
ifconfig eth1 10.1.1.1
ifconfig eth2 10.1.2.1
Unfortunately, after installing Inetutils, my host can't get the proper IP Address. This config won't work anymore after Inetutils has been installed. Please advise.

What is your netmask?

What is your netmask?
By default, any linux OS will assign /24 if we don't put netmask in ifconfig command.
Before inetutils
tc@box:~$ ifconfig | grep add
eth0 Link encap:Ethernet HWaddr AA:AA:AA:AA:AA:00
inet addr:10.1.0.1 Bcast:10.1.0.255 Mask:255.255.255.0
eth1 Link encap:Ethernet HWaddr AA:AA:AA:AA:AA:01
inet addr:10.1.1.1 Bcast:10.1.1.255 Mask:255.255.255.0
eth2 Link encap:Ethernet HWaddr AA:AA:AA:AA:AA:02
inet addr:10.1.2.1 Bcast:10.1.2.255 Mask:255.255.255.0
inet addr:127.0.0.1 Mask:255.0.0.0
tc@box:~$
After inetutils & reboot
tc@box:~$ ifconfig | grep add
inet addr:127.0.0.1 Mask:255.0.0.0
tc@box:~$

Try running the commands manually? Busybox versions may work slightly differently vs upstream ones. You can also change your script to call "busybox ifconfig" to always use that version.

No, doesn't work. The config is actually still there when I run ifconfig eth0, but I can't see any IP when I just run ifconfig. That's mean the IP is somehow not active right.
before inetutils
tc@normal:~$ ifconfig eth0

Also, I noticed that all the routing is gone once I installed inetutils and reboot it.
tc@box:~$ netstat -nr

Yeah, this is working. Thanks curaga I appreciate it. Now I can change my script to add busybox prefix.
May I know what is the explanation behind this?

Why not just add netmask in command.
Like the command is used for.
ifconfig eth0 10.1.0.1 netmask 255.255.255.0

Actually, the default netmask should be the default for the IP address class.
The default for 10.1.0.1 should be 255.0.0.0

Ah, that's right. I wanted to edit the original post but the modify button is no longer there.
Class A should be /8, B is /16, and C is /24
