Two FreeBSD machines; running a null-modem cable - one 2.2.1+ and
one 2.2.2-RELEASE.
>Description:
I've got a strange problem; two FreeBSD machines (one 2.2.1+ and one 2.2.2)
with a hardwired null-modem cable. Doing slattach's at 38400. Here's
the config's from the 2.2.1+ system:
# ifconfig sl0
sl0: flags=8011<UP,POINTOPOINT,MULTICAST> mtu 552
inet 10.0.0.8 --> 10.0.0.9 netmask 0xffffff00
# slattach -s 38400 -h -l /dev/cuaa1
/var/run/slattach.cuaa1.pid
and, here's the same information from the freshly-installed 2.2.2
system:
# ifconfig sl0
sl0: flags=8011<UP,POINTOPOINT,MULTICAST> mtu 552
inet 10.0.0.9 --> 10.0.0.8 netmask 0xffffff00
# slattach -s 38400 -h -l /dev/cuaa0
/var/run/slattach.cuaa0.pid
Now, from either system, I can ping the other (with a response time
of ~47.6ms). However, I can't ftp or telnet from one to another,
in either direction. In the past, this was caused by a VJ compression
mis-match (one had VJ and the other didn't) which is why I disabled
VJ compression on the slattach.
Now - here's the _really_ interesting part - I can nfs_mount
a file system on 10.0.0.9 exported by 10.0.0.8. ls, etc.. seem to
work fine. Telnet and FTP are the ones that hang...
>How-To-Repeat:
Set up a hardwired SL/IP connection between a 2.2.2 and 2.2.1 and
try to ftp/telnet.
>Fix:
Not clear...
