I am having a problem where I have a server running an old version of Solaris (5.6), and I need to send a file via FTP to a server that is running vsftpd. The server is not owned by my company, therefore I do not have access to this server (it also is in China). When I try to connect from the Solaris box, the connection times out, if I try from a Windows machine using any FTP client, I can connect. The Solaris box used to be able to connect to this server up until June 6th. On June 6th, the company who owns the server moved it (the virtual server IP address) from San Francisco to Beijing. Nothing changed on the Solaris box. The company says they think the problem is on our end, but it was working fine until they moved the server to China. I just need to get some info about what they need to look at on their server. I am able to connect to other FTP servers from the Solaris box, and upgrading the OS on the Solaris box is out of the question since this has a production database on it that would require $100,000+ is software upgrades on client computers. Any help will be greatly appreciated.
Thanks.

are you connecting by 'name' or 'number'?

when you ping it {the chinese server} from the windows box, is it the same IP that comes up on the Solaris box?

you might have an old entry in the /etc/hosts file that specifically put that machine at a certain address, and now that its moved, it might be different.
