Re: Fedora & Solaris 7
Thanks for the help. I'll try the tcp_windows_size tomorrow when I get back to the server. I hope that it's not a hardware problem.

Re: Fedora & Solaris 7
I think it's something much more basic. I have a lot more experience on Solaris, so if you like, email me your /var/adm/messages file and I'll have a look. Some things you can check from the solaris box... ping -s default_gateway_ip see if you're getting any packet loss. netstat -nr see if you're noticing any network errors.

I hope it's not hardware as I can't get service on the Solaris box I am trying to use ndd but the /dev/elx driver does not work with NDD AFIK.

I've talked to even older equipment than that with no problems. Hardware problems seem more likely (or something annoying like another machine on the same LAN with the same hard wired IP address). -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
Fedora & Solaris 7
G'day. I am trying to get a very old Solaris 5.7 server to ftp data to a Linux 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).
