Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

A little difficult: investigate Xenix and slattach problem

I know Xenix is a little outdated, and is dangerous to use on network.
But this is a virtual machine, and I like to play retrocomputing sometime.
The question is..why ftp over slip doesn't work?


I've set this Xenix vm on libvirt


Code:

Xenix works only with 3com network cards unavaliable on qemu
So I use the old slip protocol
On linux I make this


Code:
a)Ip forwading
echo 1 1>/proc/sys/net/ipv4/ip_forward

b)slattach
slattach -s 19200 -d -p slip /dev/pts/1

c)ifconfig on host
ifconfig sl0 192.168.7.1 dstaddr 192.168.7.2 netmask 255.255.255.252 mtu 576 up

d)Nat
iptables -A FORWARD -i sl0 -o bridge0 -j ACCEPT
iptables -A FORWARD -i bridge0 -o sl0 -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT


On xenix side
Code:
a)Create slip
mkdev slip


b)Reboot

shutdown 0


c)Create tcp

mkdev tcp 
/etc/tcp stop
/etc/tcp start
route add default 192.168.7.2  0

Now the problem coming!


Rlogin work?
Yes


And ping?
Yes from internal to external


And ftp?
If I transfer a text file empty work perfect.
But when I try binary...


Code:
ftp> put "La bionda-I wanna be your lover.mp3"
local: La bionda-I wanna be your lover.mp3 remote: La bionda-I wanna be your lover.mp3
227 Entering Passive Mode (192,168,7,2,4,30)
150 Opening BINARY mode data connection for La bionda-I wanna be your lover.mp3.


And..stuck.

What can it be?
# 2  
Xenix only supports 11.3 file names. Maybe try renaming the file to iwannabe.mp3 before transferring.
