Friends: The days 5 and 7 of this month, I sent them two mail requesting suggestions about problems that I had (I have) using ftp. Up to now nobody has answered me except for Marc Heuse in private mail. I appeal you since the answer of Marc again (to change the kernel, use at the moment the 2.4.4) he has still left me more doubts. It should have a 'pacific solution' for this problem, that is to say that doesn't commit the costs and working hours of the company. I trust them in that alone precise an orientation, for where to begin to solve the problem, I don't specify magic solutions, these don't exist. The scenario is this: a server Linux with one ADSL 128/256 kb lines in a router Cisco 777, in eth0 it is the net of the company with 45 users using Internet and electronic mail; in eth1 the router mentioned up. The server has the SuSEfirewall2-2.1 and SuSE 7.2, allowing the members of the net to consent to the mentioned services. The company has hired a server ftp (ftp.thecompany.com.ar) with the phone company of our area (Telecom). In the area of systems, two people specify to make ftp to that server and to send for the same way information to the branches that are in other towns; the software that they use in you scheme them client it is the Windows Commander and CuteFTPpro. Now then, either that they use the passive or active mode to make ftp, the server Linux freezes, totally frozen; and it is necessary to restart the server. It doesn't always happen, and it is not known which are the conditions of the server in the moment of the freezing. I cannot have solved the problem for 2 months, I have proven almost everything, from different configurations of the SuSEfirewall2-2.1 until the update of the iptables (1.2.1 at 1.2.2), but anything works. In the inetd.conf has active the Proftpd, although I am not very sure that it is relevant. Now, from D.O.S. in a machine client I use ftp and works well, very well; and Linux doesn't freeze. During the hours of more work, that is to say, all the clients using Internet and mail, it is when more 'hang'; up to four times during the morning. But in the afternoon it diminishes a lot the frequency of the freezing, until any 'hang' in hours of the night. But or less this is what happens, I wait to have explained the problem well. Some help or orientation?. Thanks folks (folks, no list) Ernesto
