We're very sorry!
Probabry it's 10th or 11th Apr, isn't it?
I was attacked too, but from outside.
I asked my network administrator about that on 13th Apr, and catched reason.
They said that their network equipments had some probrems, and fixed it.

# mt datcompression 1

# mt datcompression 1
... read
No.2
# mt datcompression 0
... write
# mt datcompression 1
... read
No.3
# mt datcompression 1
... write
# mt datcompression 0
... read
No.4
# mt datcompression 0
... write
# mt datcompression 0
... read
