CentOS - Mar 2010 - Network tuning for working with very old Solaris

G'day.

I am trying to get a very old Solaris 5.7 server to ftp data to my
updated CentOS 5.4 server but the Solaris box keeps losing
networking after sending some data.  I can't ping the Solaris box
from any of the servers on my network.

Could this be related to a much newer (modern) TCP/IP stack in
Linux and TCP options?  If so, does anyone have any suggestions
for how I can tune the Linux server?   I am not as concerned
about performance, but just to keep the Solaris box from
crashing (and no, I can't upgrade the legacy Solaris server).

Thanks,

 That in it self should tell you to look at the cabling and nic card. I
suspect its a very old nic card like ISA or begining PCI.  Just because
it is Sol 5 does not mean TCP/IP will not work.

I'd think it much more likely there's something wrong on the Solaris
box -- you don't say what the hardware is, but I remember having to
make sure the NICs did _not_ autonegotiate -- there's a way to set
that with ndd that I don't recall offhand, but no doubt Google does
:-)
