Re: [44net] JNOS 2.0j.7 autoexec.nos ?

Greetings Peter (et al), Here is the 'autoexec.nos' I run here on Hamgate.Washtenaw.AMPR.org. At the bottom, I have included the 'access.rc' TCP and IP access firewall rules. This 'autoexec.nos' is used on a DOS machine. It will require a few tweeks to have it run on a Linux box. Enjoy! --- Jay WB8TKL # autoexec.nos # # 040821 tkl - first cut # 040822 tkl - Adding ETH0 # 040825 tkl - Added AX1 # tkl - Configured to work with NOS110 version as well as 111 # 041206 tkl - Also works with JNOS2.0a (for DOS) # 051104 tkl - Including a better access.rc firewall # 060305 tkl - Configured as new YPSI Hamgate (access3.rc local.rte) # 080604 tkl - HG.LIV now CONV links to us (rather than us to him) # Also changed 'smtp timer 900' (was 300) # 'smtp maxclients 4' (was default of 10) # And changed 145.76 interface to 144.93 # 080911 tkl - Changed TCP SYNDATA to off (cheap routes won't pass SYNDATA) # Moved ann SMTP and BBS Mail settings into /nos/etc/mail.cfg # 090320 tkl - Removed conv link to Monroe (they link to us now) # 100309 tkl - Added link to MICONV # 100315 tkl - Using experimental nos2a-nr.exe # Modified autoexec.nos to support NetROM (MIYPSI WB8TKL-7) # 120418 tkl - Changed eth0 from 216.144.208.44 to 216.86.85.144 # = Chamged nameserver from 216.144.208.67 to 216.86.85.167 # # ######################################## ### Memory and System Configs ### ######################################## isat yes watchdog yes mem minalloc 32 mem ibufsize 2048 mem nibufs 7 mem debug on echo "***** Memory configured *****" pause 2 ######################################## ### Station Indentity ### ######################################## ax25 mycall wb8tkl-4 ax25 ttycall wb8tkl-5 ax25 bbscall wb8tkl-3 ax25 alias YPSI hostname HamGate.Washtenaw.AMPR.org ip address 44.102.1.1 ax25 bctext "WB8TKL-3 (YPSI) Washtenaw County AX25 & TCP/IP HamGate [www.MI-DRG.org]" # ######################################## ### Global AX.25 Parameters ### ######################################## ax25 version 2 ax25 maxframe 1 ax25 retries 10 ax25 pacl 200 ax25 window 1024 ax25 irtt 4000 ax25 timer linear ax25 t3 0 ax25 t4 1200 ax25 maxwait 9000 # ######################################## ### Global TCP/IP Parameters ### ######################################## tcp timertype linear tcp maxwait 9000 tcp retries 32 tcp window 864 tcp blimit 20 tcp irtt 4000 tcp mss 512 tcp syndata off # ip ttl 225 ip rt 4 # ######################################## ### Port Attaches ### ######################################## attach packet 60 eth0 11 1500 attach asy 0x3f8 4 ax25 144.93 576 256 9600 f1 ##attach asy 0x2f8 3 ax25 223.40 576 256 4800 f1 # attach netrom # echo "***** Attaches completed *****" pause 2 # ######################################## ### Configure the Interfaces ### ######################################## # # ETHERNET ifconfig eth0 ipaddress 216.86.85.144 ifconfig eth0 netmask 255.255.255.0 ifconfig eth0 broadcast 216.86.85.255 ifconfig eth0 descript "Ethernet to the Internet" # ifconfig eth0 tcp win 1024 ifconfig eth0 tcp irtt 50 ifconfig eth0 tcp maxw 150 ifconfig eth0 tcp mss 512 echo "***** Ethernet configured *****" pause 2 # # ENCAP ifconfig encap ipaddress 44.102.1.1 ifconfig encap netmask 255.255.255.255 ifconfig encap broadcast 255.255.255.255 ifconfig encap description "IPIP Encapsulation interface" echo "***** ENCAP configured *****" pause 2 # # COM1 [144.93] ifconfig 144.93 descript "144.93 MHz AX.25/IP Local Access port" ifconfig 144.93 netmask 0xffffff00 param 144.93 up #130 (129 = down) param 144.93 1 100 #1 Transmit delay param 144.93 2 128 #2 Persistance param 144.93 3 10 #3 Slot time param 144.93 4 10 #4 param 144.93 5 0 #5 0=half 1=full duplex param 144.93 8 1 #8 dtr param 144.93 9 1 #9 rts # # COM2 [223.40] ##ifconfig 223.40 descript "223.40 MHz 1200 baud District-2south Backbone Network" ##ifconfig 223.40 netmask 0xffffff00 ##param 223.40 up ##param 223.40 1 30 ##param 223.40 2 128 ##param 223.40 3 10 ##param 223.40 4 10 ##param 223.40 5 0 ##param 223.40 8 1 ##param 223.40 9 1 # # COM3 [phone] ##attach asy 0x3e8 5 slip phone 2048 576 19200 v ##param phone up # echo "***** IFconfig & Param completed *****" pause 2 # ################### ### NetROM ##

Unlike the TCP ACCESS command, IP ACCESS does not # restrict access to servers at the machine that is running this code. It # does however restrict the gatewaying of IP packets accross interface # ports. # # Valid PROTOCOLS are ICMP, UDP, TCP, and ANY (every thing else).
