William, I can tell you that the Red Hat 2.4.9-ac10 kernel that I'm running on one of my systems does indeed have those directories and files under /proc. I haven't had a chance to load the SuSE 2.4 stuff yet, perhaps I'll get to that after SHARE. (I have to finish up my presentations or Neale will get after me!)

I am, however, running the 2.2.16 SuSE 7.0 GA materials. Ross Patterson, who works down the aisle from me did a quick search and he didn't think there was an update to the CTC driver related to this. Perhaps someone else has seen something more specific? I have not yet worked with the SuSE 2.4 level code. Has someone seen evidence that the file noted in the doc -does- exist at the 2.4 level? I confess I'm still confused by all this... . -----Original Message----- From: Post, Mark K [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 14, 2002 3:22 PM To: [EMAIL PROTECTED] Subject: Re: Buffersize on Linux CTC Driver William, I believe that is only applicable to a system running the 2.4 kernel. Are you running that, or a 2.2 kernel? Mark Post -----Original Message----- From: Scully, William [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 14, 2002 2:27 PM To: [EMAIL PROTECTED] Subject: Buffersize on Linux CTC Driver The IBM "Linux for S/390 Device Drivers and Installation Commands" document, dated 18 July 2001, in Chapter Seven, "Linux for S/390 CTC/ESCON Device Driver", has Usage Note 2 under "Preparing the Connection" which reads: Definitions on the remote side Set up the TCP/IP on the remote side, as described in the reference manuals. This will vary depending on which operating system is used on the remote side. Note: It is important that you have IOBUFFERSIZE 32678 defined because the LINUX for S/390 CTC driver works with 32k internally. This is configurable for each device by writing the value to the buffersize file for that device (proc/net/ctc/<devicename>/buffersize ), for example echo 32768 >/proc/net/ctc/ctc0/buffersize I'm not sure how this is accomplished. Logging on as root and issuing the command doesn't work. Here's what I get: LINUXWPS:/proc # echo 32768 >/proc/net/ctc/ctc0/buffersize bash: /proc/net/ctc/ctc0/buffersize: No such file or directory What is the correct technique for creating the appropriate directories and file?
