Hi, Recently upgraded Alpha 2100 with DE300 interface and token ring from DECUNIX 3.2C to DECUNIX 4.0A , access from IBM terminaux connected to terminal server IBM3174 ,can't connect to DIGITAL via telnet. Telnet from IBM system and DEC are ok and from PC to DEC are also ok via telnet and ftp.Ping is ok from 3174 to DEC system. Port use by 3174 is 1026 and port use by Alpha is 1023. RFC 1571 and RFC 1572 are implemented on unix 4.0. We change the MTU value from 4092 to 1500 , 1492 , 1456, 576 without sucess Thanks for your help, JEAN CLAUDE [Posted by WWW Notes gateway]

Hello Jean Claude, Take a look at your connection with tcpdump. Look for the rejected connection, then back up to the TOS field of the previous packet. example: 12:26:20.366000 irvingirving.cxo.dec.com.2296 > mvssac1.rac.mci.com.ftp: . ack 60 win 33580 (DF) [tos 0xa6] <------Look at this!! 12:26:20.461648 mvssac1.rac.mci.com.ftp > irvingirving.cxo.dec.com.2296: R 447244960:447244960(0) win 0 Notice the field tos 0xa6, immediately followed by mvssac1 passing back R (reject). TOS is type of service, it is controlled by /etc/iptos file. The TOS field in the Internet datagram is to specify how the datagram should be handled. FTP and Telnet both use /etc/iptos if it is available, otherwise the application is supposed to default to values recommended by RFC1060. Create your /etc/iptos owned by bin, bin 755 permissions and have it contain the following: ftp-control tcp 0x10 ftp-data tcp 0x08 telnet tcp 0x10 That should fix you up!
