- Hello,
-
- I have two remarks:
-
- 1. You might try pppd-1.01-beta from for the sparcs to get the most
- ripe non-dialup version. Despite it's 'beta' status, it has the
- most kernel memory allocation/deallocation bugs removed. It's more
- advanced than the pl6 version you mentioned, as far as I know.
-
- ftp to merit.edu, directory /pub/ppp, file pppd-1.01-beta.tar.Z
-
- 2. You might want to try dp-2.2-beta.tar.Z (or -gamma, it that exists
- by now..) to get the dialup ppp package [and tell Kirk Smith
- (ks@acn.purdue.edu) to add yo to the mailing list]. It simulates
- keeping the network connection up, but has time-outs on the phone
- line, so that if (all configurable) the last tcp connection was
- closed, the phone line hangs up after 6 seconds, if the last tcp
- transmission actually occured 10 minutes ago, the phone hangs up,
- or 30 seconds after the last UDP packet... you get the idea. It
- then does an automatic redial, if traffic occurs again.
-
- The 2.2-beta version has some minor Makefile/include file problems
- (Kirk has my diffs for it), and tends to crash when you have an
- error in the configuration script (deref'ing zero pointers), but
- works like a charm otherwise, AND IT SUPPORTS LOADABLE KERNEL
- MODULES... at least half (i.e., you can load them, but if you do
- the unloading, the system crashes when it tries to do networking
- again). But I think it's better to only reboot the machine to
- remove or update the ppp if you want it, than to built a new kernel
- and reboot the machine :-) Maybe SUN never tested this part of
- their Kernel code? I think they don't have any loadable network
- modules of their own.
-
- ftp to phoenix.acn.purdue.edu, directory pub, and get PPP.readme
- (1k) with further advice.
-
- You might want to configure the sendmails at both ends to only
- actually send the mail, say, two times a day, to minimize costs
- [mark the connection expensive].
-
- I used both packages. I like the latter better, because it's less work
- and less to backup if you want to install it, and because I won't get
- 'how is the ppp startup command' phone calls all the time.
-
- BTW: nfs? You might want to completely avoid it. Try mounting a remote
- filesystem to get the feeling. Basically, you have to avoid
- anything which does stats because they cause lots of traffic, and
- anything which does writes because nfs writes always wait for the
- 'written to disk' confirmation from the other side.
