- Gaige:
-
- 1) I switched to System 4.1 on the Plus and the problem with Telnet
- not recognizing "option" as "control" disappeared. Perhaps you could
- mention that System 4.1 is required in the Preface under "System
- Requirements".
-
- Thanks for the info.
-
- 2) However, the old, separate numeric keypad still does not work correctly.
- You did not indicate whether I should expect it to. Will you be able
- to support this device?
-
- There must be a mechanism to specify the "arrow keys" versus "+", "*"
- "/" ",". VersaTerm uses "command-arrowkey" to do this.
-
- Thanks, Herb.

- I vote to remove the blinking screen when bell characters are received,
- (or make it an option, as suggested.)

- I have a copy of this now and it looks great but I can't get

- Any ideas?? Any undocumented configuration parameters??

- Can someone tel me the locations to patch??

- Does anyone know how to get NCSA Telnet to access a subnet of
- a class B net (i.e. subnet mask 255.255.255.0)? I have tried
- all kinds of values in the "Use Subnetting Mask" box of NCSA
- Telnet version 2.0 (a great piece of software at the perfect
- price!), including "ffffff00", "ff.ff.ff.0", "0xff.0xff.0xff.0",
- all of the previous with "F"s, and 255.255.255.0. All cases
- seem to have no effect; from what I can see (with tcpdump on
- a Sun) it looks like the Kbox catches the packet, makes its own
- decision as to whether it is going to a different network (which
- doesn't detect subnets) and arps for the host on the attached
- Ethernet (which the host isn't attached to).
-
- The Kbox is running release # 5 of the KIP code (I assume...
- the srec file I load to it is "at-gw.srec.5").
-
- Any help will be greatly appreciated,

- Brad,
- NCSA Telnet attempts to route packets to the best of its ability, but as
- far as the K-Box is concerned it has no say in the matter (although this
- feature does work with the EtherSC, EtherPortSE, and EtherTalk cards).
- Since I have a very similar networking problem, I know what you are going
- though, I was unable to find an "off the shelf" gateway that would handle
- class B with 8 bit subnets and no promiscuous gateways. To the rescue comes
- the KIP code. Although it doesn't handle the subnetting correctly by default,
- source code is available, so a small tweaking of the code makes routing
- more effective.
-
- Good luck!

- The current format for NCSA Telnet subnet masks is eight hexidecimal digits
- indicating an actual bit mask for the IP number. The most common example,
- for a class B net with eight bits of subnetting is "ffffff00", which happens
- to be the same as class A, sixteen bits of subnet. Similarly, class A with
- eight bits is "ffff0000."
-
- It is important to note that if the kinetics box stradles subnets (has one
- IP net number on the ethernet side and a different one on the AppleTalk side),
- the AppleTalk side of the Kinetics box must be specified as a gateway in the
- config.tel file. An example of this is a KBox running the combined gateway from
- kinetics with 128.174.20.1 Ethernet and 128.174.22.1 AppleTalk. Assuming a
- class B, eight bit subnet, the subnet mask would be "ffffff00" and the following
- entry should be in the config.tel:
-
- name=Kbox hostip=128.174.22.1 gateway=1
-
- I hope this helps,
