In clearing out my older archives, deduplicating the redundant, etc. I still found many Debian files missing from or not present in official Debian locations. Some of these may also be older than what Debian may wish to preserve. I believe they all date from slink (2.1) through woody (3.0). I believe I much earlier well verified them (e.g. via signature on Package files of hashes of files themselves), and also preserved the modification times (HTTP Last-Modified, FTP MDTM) from the earlier official Debian locations. I believe all these files came from the ftp.debian.org (or possibly official mirror thereof, but in all cases still verified, etc.) and/or security.debian.org site, and are under those corresponding (ftp.debian.org security.debian.org) directory names.
For convenience, here's listing of these 92 files: adjtimex_1.6-2.deb apt_0.1.10_i386-libc5.deb apt_0.1.9.deb bind-doc_8.2.2p5-1.deb bind-doc_8.2.2p5-11.deb bind-doc_8.2.3-0.potato.3_all.deb bind_8.1.2-5.deb binutils_2.9.1.0.19a-2.deb cfingerd_1.3.2-18.deb courtney_1.3-4.deb cron_3.0pl1-50.deb debconf_0.2.69.deb dnsutils_8.1.2-5.deb dosemu_0.98.7-1.deb dpkg-dev_1.4.0.34.deb dpkg_1.4.0.34.deb dump_0.4b4-13.deb enscript_1.6.1-1.deb filters_1.7.deb fsresize_0.07-1.deb gdb_4.17-4.m68k.objc.threads.hwwp.fpu.gnat.3.deb gif2png_0.99-2.deb gimp_1.0.4-2.0.1.deb groff_1.11a-7.deb groff_1.15-3.deb gs_5.10-1.deb ldso_1.9.11-5.deb libc6-dev_2.1.1-2.deb libc6-dev_2.1.2-11.deb libc6-pic_2.1.1-2.deb libc6-pic_2.1.2-11.deb libc6_2.1.1-0.2.deb libc6_2.1.1-2.deb libc6_2.1.2-0pre12.deb libc6_2.1.2-11.deb libhdf4g_4.1r2-5.1.deb libjpeg62_6b-1.1.deb libncurses4_4.2-3.2.deb libncurses5_5.0-2.deb libpam-modules_0.72-1.deb libstdc++2.10_2.95.2-5.deb libstdc++2.9-glibc2.1_2.91.66-1.deb libstdc++2.9_2.91.60-5.deb libungif3g_3.0-2.deb libwww-perl_5.36-1.deb lpr_0.33-3.deb lynx_2.8.2-4.deb makedev_2.3.1-19.deb man-db_2.3.10-68.deb man-db_2.3.10-70.deb mgetty-docs_1.1.21-2.1.deb ncftp_3.0beta16-1.deb netscape-base-4_4.61-22.deb newscache_0.99.14-1.deb nfs-server_2.2beta37-1.deb nis_3.3.1-1.deb nvi-m17n-canna_1.79+19991117-1.deb nvi-m17n-common_1.79+19991117-1.deb nvi-m17n_1.79+19991117-1.deb nvi_1.79-13.deb nvi_1.79-9.deb perl-base_5.004.04-7.deb perl_5.004.04-7.deb ppp-pam_2.3.10-2.deb ppp-pam_2.3.8-1.deb ppp_2.3.10-2.deb ppp_2.3.8-1.deb procmail_3.10.7-7.deb procps_2.0.6-4.deb samba-doc_1.9.18p10-7.deb samba-doc_2.0.7-3.deb samba_1.9.18p10-7.deb sendmail_8.9.3-1.deb sendmail_8.9.3-3.deb setiathome_1.3-3.deb sharutils-doc_4.2-8.deb sharutils_4.2-8.deb slrn_0.9.5.3-4.deb slrnpull_0.9.5.3-4.deb sysutils_1.3.4.deb telnet_0.12-4.deb telnetd_0.12-4.deb tetex-base_0.9.981113-1.deb tetex-bin_0.9.981113-2.deb tetex-extra_0.9.981113-1.deb util-linux_2.10d-4.deb util-linux_2.9w-1.deb xinetd_2.2.1-8.deb xlib6_3.3.5-2.deb xlib6g_3.3.5-2.deb xpdf_0.90-7_i386.deb xv-doc_3.10a-25.deb Files may be obtained under: https://old-debian.balug.org/ For more details on the pathnames to those files, see: https://old-debian.balug.org/README.txt References / See Also: https://old-debian.balug.org/README.txt does what the program name implies: https://www.mpaoli.net/~michael/bin/find_deb_in_snapshot.debian.org.txt (same file, above is workaround for web server's handling of below) https://www.mpaoli.net/~michael/bin/find_deb_in_snapshot.debian.org https://bugs.debian.org/933728 (files needed to complete the debian-30r0-i386-binary ISO files and where to obtain them, etc.)
