(This only applies where the peer is authenticating itself to you, of course.) -What's new in ppp-2.3.7. -************************ +What's new in ppp-2.3.10. +************************* + +* Pppd now supports `plugins', which are pieces of code (packaged as + shared libraries) which can be loaded into pppd at runtime and which + can affect its behaviour. The intention is that plugins provide a + way for people to customize the behaviour of pppd for their own + needs without needing to change the base pppd source. I have added + some hooks into pppd (places where pppd will call a function + pointer, if non-zero, to replace some of pppd's code) and I will be + receptive to suggestions about places to add more hooks. Plugins + are supported under Linux and Solaris at present. + +* We have a new maintainer for the Solaris port, Adi Masputra of Sun + Microsystems, and he has updated the Solaris port so that it should + work on 64-bit machines under Solaris 7 and later. + +* Pppd now has an `allow-ip' option, which takes an argument which is + an IP address (or subnet) which peers are permitted to use without + authenticating themselves. The argument takes the same form as each + element of the allowed IP address list in the secrets files. The + allow-ip option is privileged and may be specified multiple times. + Using the allow-ip option should be cleaner than putting a line like + `"" * "" address' in /etc/ppp/pap-secrets. + +* Chat can now substitute environment variables into the script. This + is enabled by the -E flag. (Thanks to Andreas Arens for the patch.) + +* If the PAP username and password from the peer contains unprintable + characters, they will be translated to a printable form before + looking in the pap-secrets file. Characters >= 0x80 are translated + to a M- form, and characters from 0 to 0x1f (and 0x7f as well) are + translated to a ^X form. If this change causes you grief, let me + know what would be a better translation. It appears that some peers + send nulls or other control characters in their usernames and + passwords. + +* Pppd has new `ktune' and `noktune' options, which enable/disable + it to change kernel settings as appropriate. This is only + implemented under Linux, and requires the /proc filesystem to be + mounted. Under Linux, with the ktune option, pppd will enable IP + forwarding in the kernel if the proxyarp option is used, and will + enable the dynamic IP address kernel option in demand mode if the + local IP address changes. + +* Pppd no longer requires a remote address to be specified for demand + dialling. If none is specified, it will use a default value of + 10.112.112.112+unit_number. (It will not propose this default to + the peer.) + +* The default holdoff is now 0 if no connect script is given. + +* The IPV6 code from Tommi Komulainen, which I unfortunately only + partially merged in to ppp-2.3.9, has been fixed and updated. + +* The linux compilation glitches should be fixed now. + + +What was new in ppp-2.3.9. +************************** + +* Support for the new generic PPP layer under development for the + Linux kernel. + +* You can now place extra options to apply to specific users at the + end of the line with their password in the pap-secrets or + chap-secrets file, separated from the IP address(es) with a "--" + separator. These options are parsed after the peer is authenticated + but before network protocol (IPCP, IPXCP) or CCP negotiation + commences. + +* Pppd will apply the holdoff period if the link was terminated by the + peer. It doesn't apply it if the link was terminated because the + local pppd thought it was idle. + +* Synchronous support for Solaris has been added, thanks to John + Morrison, and for FreeBSD, thanks to Paul Fulghum. + +* IPV6 support has been merged in, from Tommi Komulainen. At the + moment it only supports Linux and it is not tested by me. + +* The `nodefaultip' option can be used in demand mode to say that pppd + should not suggest its local IP address to the peer. + +* The `init' option has been added; this causes pppd to run a script + to initialize the serial device (e.g. by sending an init string to + the modem). Unlike the connect option, this can be used in a + dial-in situation. (Thanks to Tobias Ringstrom.) + +* There is a new `logfile' option to send log messages to a file as + well as syslog. + +* There is a new, privileged `linkname' option which sets a logical + name for the link. Pppd will create a /var/run/ppp-.pid + file containing its process ID. + +* There is a new `maxfail' option which specifies how many consecutive + failed connection attempts are permitted before pppd will exit. The + default value is 10, and 0 means infinity. :-) + +* Sundry bugs fixed. + + +What was new in ppp-2.3.8. +************************** + +* The exit status of pppd will now indicate whether the link was + successfully established, or if not, what error was encountered. + +* Pppd has two new options: fdlog will send log messages to file + descriptor instead of standard output, and nofdlog will stop log + messages from being sent to any file descriptor (they will still be + sent to syslog). Pppd now will not send log messages to a file + descriptor if the serial port is open on that file descriptor. + +* Pppd sets an environment variable called PPPLOGNAME for scripts that + it runs, indicating the login name of the user who invoked pppd. + +* Pppd sets environment variables CONNECT_TIME, BYTES_SENT and + BYTES_RCVD for the ip-down and auth-down scripts indicating the + statistics for the connection just terminated. (CONNECT_TIME is in + seconds.) + +* If the user has the serial device open on standard input and + specifies a symbolic link to the serial device on the command line, + pppd will detect this and behave correctly (i.e. not detach from its + controlling terminal). Furthermore, if the serial port is open for + reading and writing on standard input, pppd will assume that it is + locked by its invoker and not lock it itself. + +* Chat now has a feature where if a string to be sent begins with an + at sign (@), the rest of the string is taken as the name of a file + (regular file or named pipe), and the actual string to send is taken + from that file. + +* Support for FreeBSD-2.2.8 and 3.0 has been added, thanks to Paul + Fulghum. + +* The Tru64 (aka Digital Unix aka OSF/1) port has been updated. + +* The system panics on Solaris SMP systems related to PPP connections + being established and terminated should no longer occur. + +* Fixed quite a few bugs. + + +What was new in ppp-2.3.7. +************************** * Pppd can now automatically allocate itself a pseudo-tty to use as the serial device.
