-@(#) README.IRIX 1.2 94/12/28 18:45:58
-
-In the past few months I received several messages with questions from
-people that tried to use my tcp wrapper on IRIX 5.x. Some mysteries
-could be solved via email, and then some remained.
-
-Today I finally had a chance to do some tests on someones IRIX 5.2
-system. Here is my first-hand experience with wrapper release 6.3.
-
-(1) Inetd is broken. Normally one edits inetd.conf, sends a HUP signal
- to inetd and that's it. With IRIX evil things happen: inetd is too
- stupid to remember that it is already listening on a port.
-
- In order to modify an entry in inetd.conf, first comment it out
- with a # at the beginning of the line, kill -HUP the inetd, then
- uncomment the inetd.conf entry and kill -HUP again.
-
- Even with this amount of care I have seen inetd messing up, like
- calling rusersd when I make a talk connection. Even killing and
- restarting inetd does not solve all problems.
-
- I find it hard to believe, it but the best thing to do with IRIX is
- to reboot after changing inetd.conf.
-
-(2) When tcpd is built according to the irix4 Makefile rules, it
- appears to work as expected with TCP-based services such as
- fingerd, and with UDP-based services such as ntalk and tftp.
-
-(3) It does NOT work with RPC over UDP services such as rusersd and
- rstatd: the wrapper hangs in the recvfrom() system call, and I
- have spent several hours looking for ways to work around it. No
- way. After finding that none of the applicable socket primitives
- can be made to work (recvfrom recvmsg) I give up. So, the IRIX RPC
- services cannot be wrapped until SGI fixes their system so that it
- works like everyone elses code (HP Sun Dec AIX and so on).
-
-(4) I didn't even bother to try the RPC over TCP services.
-
-(5) When an IRIX 5.2 system is a NIS client, it can have problems with
- hosts that have more than one address: the wrapper will see only
- one address, and may complain when PARANOID mode is on. The fix is
- to change the name service lookup order in /etc/resolv.conf so that
- your system tries DNS before NIS (hostresorder bind nis local).
-
-(6) IRIX 5.2 is not System V.4, and it shows. Do not link with the
- -lsocket and -lnsl libraries. They are completely broken, and the
- wrapper will be unable to figure out the client internet address.
- So, TLI services cannot be wrapped until SGI fixes their system so
- that it works the way it is supposed to.
-
-I am not impressed by the quality of the IRIX system software. There
-are many things that work on almost every other system except with IRIX.
