   I am working with UW2.0.1 . I am facing one strange problem in my server. Whenever we  tries to ftp big files to this server or from this server, the system is disconnecting from the network. after this i am not able to telnet this machine from my other machines. ie. tottally disconnecting from the network.. This is happening only if u tries to ftp big file (more than 1MB) from this server or to this server.

I have seen this before. It seems like your NIC card is having problems.  Either a.) with the bus, or b.) with the OS.  I had the same exact symptons as your having, I swapped out the card and they all went away.

UnixWare 2.0.1 is extremely old and suffers from many, many networking bugs. you may be able to fix this problem, but I recommend STRONGLY that you upgrade to UnixWare 2.1.3.

ptf2006 may help in this situation.  It's the only UW20x networking ptf which seemed relevant.  Get it at

Again, the answer here is you must upgrade to UnixWare 2.1.3.  UW201 has many problems.  It's not y2k compliant, for instance.
