The connection is Dial-on-demand, so the connection will be setup when needed. We have a problem when there is something to print and the connection is not active. The router is setting up the connection but nothing is printed. If we look at the netstat command on the AS/400 it is saying LPD port 515 syn-sent. The output in the Queue has the SND status but nothing happens anymore. At the end of the day it is still in SND status. No calls are initiated again. No errors are reported. If i do a ping to setup a call and print something from the queue when the communication is active it works fine..... So when the call is initiated by LPR it fails. According to RFC1179 the LPR has to use port 721-731 but the AS/400 is always using a different port. CAN SOMEBODY HELP ME OR IS IT A BUG?? Thanx Henk van Gruijthuijsen codit@codit.nl There very well may be a bug somewhere. When problems like this occur, it can take considerable time. You plan something expecting it to work and you must spend weeks getting it to work. We had a problem last year with IPDS printers on our TCP/IP network disconnecting at some remote sites. This only occured at 2 or our 17 sites. We had to have IBM install a lan sniffer and monitor the line. Once they captured the condition, they could send the capture files to their experts. They were able to determine that it only occured on certain version of firmware in the IPDS printers. It turned out that we could solve the problem by making sure the TCP/IP keep alive setting on the routers at the remote site was greater than the value in the printers. I never would have determined that on my own. JHicks@SUZ.com
