From 97fd59b025edf7d0029806e5015f9a3ef8c1b32b Mon Sep 17 00:00:00 2001 From: Jesse Rosenstock Date: Sun, 7 May 2023 17:21:23 +0200 Subject: tcpdump.1.in: Delete Linux 2.0 references Delete Linux 2.0 bugs from bug list. Linux 2.0.x releases are from 1996-2004. The man page recommended upgrading to Linux 2.2, released in 1999. https://en.wikipedia.org/wiki/Linux_kernel_version_history#Releases_up_to_2.6.0 I'm assuming these >20 year old bug references aren't that useful now. --- tcpdump.1.in | 18 ------------------ 1 file changed, 18 deletions(-) (limited to 'tcpdump.1.in') diff --git a/tcpdump.1.in b/tcpdump.1.in index 2fa50b5b..b51c4eb6 100644 --- a/tcpdump.1.in +++ b/tcpdump.1.in @@ -2052,24 +2052,6 @@ in the tcpdump source tree root.
