 |
|
My vpn connection stopped working "suddenly". I did some testing and discovered that the
| Code: | | ioctl(ppp_dev_fd, PPPIOCSCOMPRESS, (caddr_t) &data) |
call in ccp_test() in sys-linux.c is returning EINVAL for the MPPE bits.
My kernel, 2.6.10-gentoo-r6, has MPPE compiled in, not a module.
This has been working fine for months. It is possible that a recent "emerge -uD world" broke something. My VPN requires MPPE.
Any ideas why that ioctl should fail? |

The deflate compressor or gzip compressor module is not loaded
Can you check your /proc/config.gz (or /proc/config or /usr/src/linux/.config) for inclusion of ZLIB and PPP_DEFLATE?

I tinkered around some more and discovered that the MPPE driver was not registering at boot time. The following line should be in my boot log, but it was missing:
PPP MPPE Compression module registered
I finally gave up and rebuilt my kernel with MPPE as a module:
Compiled in Kernel: PPP
Kernel Module: PPP-MPPE, SHA1, SHA256, SHA512, ARC4
Set "mpppe stateless" in options.pptp
It really worked for six months with PPP-MPPE compiled into the kernel.
Thanks, |
