It has been successfully used as both -a client and server. Below are the only issues that I -know of. - -1) Large packet ping causes RTEMS box to lock up - If you ping the RTEMS box over the ppp link with a packet - size greater than 1500, the RTEMS box locks up. I think - the problem is in the pppd ethernet driver. - -2) Upgrade the libnetworking/modem files - This upgrade did not modify the ppp ethernet driver files - in the libnetworking/modem directory. Would like to - upgrade these files. Hopefully, it will fix the large - packet ping problem. - -3) The files cbcp.c and cbcp.h provide a callback feature - that I have not tried to compile or use. The files in - this directory are identical to the 2.3.11 versions. - for completeness. - - -JOEL: Are the modifications to the original pppd such that the - real maintainers will accept them? - -No. The pppd 2.3.11 branch is an old branch. The current -version is 2.4.x and it contains alot of extra items that -just did not make sense to have in an embedded environment. -I could make the RTEMS changes compatible with the standard -2.3.11 release by using compilation flags. I have not -contacted the maintainers to see if they are interested. - +The pppd application seems to very stable. It has been tested using +the example application with the i386/pc586 and m68k/sbc5206e BSPs. +The tests were executed using a null modem serial cable to connect +with a UNIX box running either the ppp or pppd application and with +an external modem to dial up a local ISP. + +If you have problems getting your target to make consistent connections +with an ISP, the problem is most likely with the ppp options. First +try using the "novj" and "noaccomp" options. If you have questions +about what other option values are available for the rtems_pppd_set_option +function, please look at the pppd.8 man page file or the the source code. +The majority of options that are documented in man page should work +with this function call. + +The pppd application requires the BSP termios driver support task +driven I/O. Below is a list of known issues that need to be resolved: + + - pppd locks up when it receives large packet pings (> 1500 bytes) + - pppd occasionaly locks up with mbuf allocation error + (problem is rare and may be BSP related) + +If you find any other problems or fix some problems, please post your +changes to the RTEMS mailing list. + +Good Luck |
