Item 1. Security and Issuer

This statement relates to the common stock, par value $.001 per share ("Common Stock"), of Tut Systems, Inc., a Delaware corporation ("Company"), whose principal executive offices are located at 5964 W. Las Positas Blvd, Pleasanton, CA 94588. The approximate aggregate percentage of shares of Common Stock reported beneficially owned by each person herein is based on 16,482,428 shares outstanding, which is the total number of shares of Common Stock outstanding as of October 30, 2002, as reflected in the Company's Form 10-Q filed with the Securities and Exchange Commission ("Commission") on October 31, 2002. Unless otherwise indicated, the holdings reported herein are as of the close of business on October 31, 2002.

Item 2. Identity and Background

(a) This statement is filed by Kopp Investment Advisors, Inc. ("KIA"), with respect to shares of Common Stock beneficially owned directly by it and held in discretionary accounts managed by KIA; Kopp Holding Company ("KHC") solely as the parent corporation of KIA and indirect beneficial owner of the shares beneficially owned by KIA; Kopp Emerging Growth Fund ("KEGF") with respect to shares owned directly by KEGF; and LeRoy C. Kopp individually with respect to shares of Common Stock beneficially owned directly by him and indirectly by him by virtue of his ownership of all of the stock of KHC and otherwise. The foregoing persons are sometimes referred to as "Reporting Persons". Certain information concerning the directors and executive officers of the corporate Reporting Persons is set forth on Schedule A attached hereto and incorporated herein by reference. Any disclosures with respect to persons other than the Reporting Persons are made on information and belief after making inquiry to the appropriate party.

(b) The business address of each of the Reporting Persons and directors and executive officers is 7701 France Avenue South, Suite 500, Edina, MN 55435.

(c) The principal business of KIA is that of an investment advisor managing discretionary accounts owned by numerous third-party clients, including KEGF, a registered investment company incorporated under Minnesota law. KHC is a holding company engaged, through subsidiaries, in the investment industry. The principal occupation of Mr. Kopp is serving as the president of KHC and KIA.

(d) None of the persons referred to in paragraph (a) above has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations and/or similar misdemeanors).

(e) None of the persons referred to in paragraph (a) above has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) KIA and KHC are Minnesota corporations. KEGF is a series of Kopp Funds, Inc., a Minnesota corporation. Mr. Kopp and all other directors and executive officers of the Reporting Persons are citizens of the United States.

Item 3. Source and Amount of Funds or Other Consideration

The net investment cost (including commissions, if any) of the shares of Common Stock directly or indirectly beneficially owned by Mr. Kopp, which includes shares beneficially owned by the other Reporting Persons, at October 31, 2002, was $21,398,484.85. The shares beneficially owned by KIA were purchased with the investment capital of KIA or the investment capital of the owners of the discretionary accounts. The shares beneficially owned by KEGF were purchased with the working capital of the mutual fund. The shares beneficially owned by Mr. Kopp were purchased with his investment capital or the funds of a 501(c)(3) corporation. See Item 5 below.

Item 4. Purpose of Transaction

The Reporting Persons acquired the shares of Common Stock for investment purposes, and the Reporting Persons intend to evaluate the performance of such securities as an investment in the ordinary course of business. The vast majority of the shares covered hereby are separately owned by hundreds of discrete, independent persons, including a single registered investment company. These persons do not act in concert in any way. The Reporting Persons pursue an investment objective of long term capital appreciation. In pursuing this investment objective, the Reporting Persons analyze the management, operations and markets of companies in which they invest, including the Company, on a continual basis through analysis of research and discussions with industry and market observers and with representatives of such companies.

Each Reporting Person that owns shares of Common Stock assesses the Company's business, financial condition, and results of operations as well as economic conditions and securities markets in general and those for the Company's shares in particular. Depending on such assessments, one or more of such Reporting Persons may acquire additional shares or may sell or otherwise dispose of all or some of the shares of Common Stock. Such actions will depend on a variety of factors, including current and anticipated trading prices for the Common Stock, alternative investment opportunities, and general economic, financial market, and industry conditions.

Except as described in this Item 4, none of the Reporting Persons nor any other person named in Schedule A has any plans or proposals that relate to, or would result in, any matter required to be disclosed in response to paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. The shares of Common Stock were not acquired for the purpose, nor with the effect, of changing or influencing the control of the Company. Neither any of the Reporting Persons nor any client or shareholder thereof is a member of a "group" for any purpose.

Item 5. Interest in Securities of the Issuer

Generally by virtue of limited powers of attorney and/or investment advisory agreements, KIA is the beneficial owner of 4,317,250 shares, or 26.2%, of the Common Stock. KIA has sole voting power over a minority percentage of the aggregate shares managed for clients. Under its standard investment agreement, KIA does not vote its clients' shares. KIA manages and votes shares owned by KEGF. By virtue of the relationships described in Item 2 of this statement, KHC and Mr. Kopp have indirect beneficial ownership of the shares beneficially owned by KIA.

Mr. Kopp's direct beneficial ownership may comprise Common Stock held by the Kopp Family Foundation ("KFF"), for which he serves as a director; held by the LeRoy C. Kopp Individual Retirement Account ("IRA"); held directly by him or by his wife's IRA. The KFF is the direct owner of 150,000 shares, or less than 1% of the Common Stock. The IRAs own 710,000 shares, or over 4%, of the Common Stock. Mr. Kopp owns directly 162,500 shares. In the aggregate, including the shares beneficially owned by KIA, under Section 13 of the Securities Act of 1934, Mr. Kopp may be deemed beneficially to own a total of 5,339,750 shares, or 32.4%, of the Common Stock.

(b) KIA has sole power to vote 2,553,500 shares of the Common Stock. Pursuant to the limited powers of attorney granted to KIA by its clients, which generally are terminable immediately upon notice, KIA in effect shares with the majority of its thousands of clients the power to dispose of the Common Stock owned individually and of record by them. KIA has sole power to dispose of 1,765,000 shares. In effect Mr. Kopp has sole power to dispose of and to vote the Common Stock beneficially owned directly by him.

(c) The identity of the Reporting Person, type of transaction, date, number of shares, and price per share (excluding commission) for all transactions in the Common Stock by the Reporting Persons within the past 60 days are set forth on Schedule B attached hereto and incorporated by reference herein. Substantially all trades by the Reporting Persons are done in the over-the-counter market.

(d) With the exception of the thousands of clients of KIA and the employees of KHC, no person other than each respective record owner of shares of Common Stock is known to have the right to receive or the power to direct the receipt of dividends from or the proceeds of the sale of such shares of Common Stock.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Except as otherwise expressly disclosed herein, there are no contracts, arrangements, understandings, or relationships (legal or otherwise) among the persons named in Item 2 hereof or between such persons and any other person with respect to the Common Stock. The filing of this Schedule shall NOT be construed as an admission that a Reporting Person or any other person is a beneficial owner of any shares of Common Stock for any purpose, including for purposes of Sections 13, 14 or 16 of the Securities Exchange Act of 1934, as amended from time to time. KIA does not act as an agent of any client to enter into any agreement to act as a group with others for the purpose of acquiring, holding, or disposing of the securities of an issuer or to gain corporate control or to influence coporate affairs of an issuer. KIA and affiliates and associates are not affiliated with the issuer.
