I'm using the very initial release of perl5 for some HTML processing but didn't bother to build socket support since I didn't have immediate need for it. I just looked at the latest version (5.001m) and it still support only NETLIB so I guess you did the porting yourself. In that case it won't be easy for me to reproduce your situation. Bad file number error (I assume perl is printing that out in response to receiving EBADF error from socket calls) means that you are passing down bad socket to any of the socket calls. You might want to check what kind of value you received from socket() call and see if you are properly handing them down to other socket calls. Also if you could obtain NETLIB, it might make your life easier. -- Hiroto Shibuya Process Software Corporation ================================================================================ Archive-Date: Tue, 15 Aug 1995 05:24:41 GMT Subject: Why does DECwindows need hosts?

But this might be more becuase of issues with the MAIL$ RTL routines (haven't traced it down).

Just add fake entries to the hosts database for your PCs. You can use something like PC1, PC2, ... where the number doesn't mean anything or is the local host number from the Internet Address for the PC. The name doesn't have to match what the PC is using. DECwindows may do this for security reasons - figuring that a host that is registered in the name database is probably more legit than one that is not. - Bernie Volz Process Software Corporation ================================================================================ Archive-Date: Wed, 30 Aug 1995 13:49:39 GMT Subject: Amount of Telnet users on a VMS host Message-ID: <809794181.5221@b-fawlty.demon.co.uk> From: harvey@b-fawlty.demon.co.uk (Harvey Lang) Date: Wed, 30 Aug 1995 13:49:39 GMT Hi, I wonder if anyone can provide information regarding loading on a VAX host for Telnet connections via TCPware.

However, you'll of course be limited by the VMS user license you have and process limits. I'd suggest using AUTOGEN w/FEEDBACK after running for a while - that is generally a good tuning approach. You'll probably need more non-paged dynamic memory (and on older VMS systems, more LRP and IRP buffers). As far as performance goes, LAT is more efficient (assuming you're using terminal servers) because it can handle multiple connections in each packet - TELNET (TCP/IP) uses a separate packet for each connection. TELNET & TCP/IP are general networking protocols. LAT was specifically designed for terminal/printer access in a LOCAL area network. On the other hand, we've worked hard to make the TCPware TELNET server code work as efficiently as possible. I always recommend to folks ... use LAT where appropriate, use TELNET where appropriate. For example, for WAN access you can only use TELNET. If you have systems that don't run LAT, use TELNET. If you have terminal servers that can do either, chose LAT if you can but using TELNET is fine too. Hope that helps. - Bernie Volz Process Software Corporation ================================================================================ Archive-Date: XXX, 30 Aug 1995 23:05:44 -0400 Subject: TCP/IP for VMS 4.7 Message-ID: <4238u8$832@newsbf02.news.aol.com> From: bfravel@aol.com (BFravel) Date: 30 Aug 1995 23:05:44 -0400 Reply-To: bfravel@aol.com (BFravel) Sender: root@newsbf02.news.aol.com We have an old system that must stay at 4.7.
