开云体育I have made a bunch of progress which might be helpful: 1. Created a standalone X.25 module for Raspbian based off Kernel??5.15.32-v7+ (this was on a Raspberry Pi 2) a. The recipe for this is pretty easy, and really just a case of downloading the kernel source, and doing: cd /usr/src/linux/net/x25 CONFIG_X25=m make -C /lib/modules/$(uname -r)/build/ M=$(pwd) 2. Compiled jh-xotd () a. There is something wrong with the getopt in line 232. ?However if you change -1 to 255 it works b. You need a script file as: #!/bin/sh -e echo "Setting up $1" > /dev/console ip link set $1 up route --x25 add 0/0 $1 c. And a config as: tun0?10.0.0.2 /home/dave/jh-xotd/xotd-setup 256 This is somewhat difficult as it needs you to specify the remote destination, so that needs some work, as honestly we want this “Dynamic”. ?However it will work for testing. ?Here 10.0.0.2 is my Cisco. ?The tun0 is important for the moment, for Pad_srv. ?However it kinda makes sense when you think that probably most links where Point to Point. ? Worst case I think you can use the Cisco as a border XOT router to this. 3. Compiled pad_svr () a. Modify Makefile to put -lrt at the end pad_svr gcc line not at the start. ?Else you will get complaints about timer_X (e.g. timer_create) b. Modify "open_x25.c” look for a line as 'strcpy(subscription.device, “X”)’. ?Change the X to be the device you configured in the jh-xotd config c. Create a pad_svr config as: #This is config file for pad_svr program. # local_x121_address 1111 log_level 5 log_path /var/log/pad_svr.log ? Watchdog_timeout 10 Winsize_in 2 Pacsize_in 128 Forward_idle_timeout 1 x29_profile 1:0,2:0,3:0,4:1,13:4,15:0
Buffer_size 32000 Change the x121 address to be the address of this instance (i.e. whatever your put in the x29 route on the Cisco) 4. From a Cisco configure XOT route to point at IP of Linux box, with the address pad X <- Address from pad_svr If it all works you should be prompted to login. ?Ok you now having comms... If you tcpdump of tun0 you will be able to see the raw X.25 frames. ?Now that I can do all that I think it might be possible to make this work with RSX11M, if I can make a DEC synchronous interface join “tunX”. ?
